1.0 Introduction and Background

Task Order (TO) M16PD00025 was issued to HDR on 16 May 2016. Under this Timeand-Material (T&M) TO, HDR will conduct field monitoring during wind turbine generator 

(WTG) installation and operations at the Block Island Wind Farm (BIWF), Rhode Island. 

The work to be performed under this TO falls within the objectives identified in the basic 

IDIQ Contract number M15PC00002 and specifically Tasks C.5.2.1, C.5.2.2, C.5.2.4 and 

C.5.3.

This revised Work Execution Plan (WEP)/Field Sampling Plan (FSP) supplements the 

information provided in the Field Data Collection Plan prepared under TO M16PD00006

and it incorporates response to clarifications sought by BOEM on the draft version of the 

plan dated June 8, 2016. All revisions are shown in RED font for easy reference. It 

provides additional details on the HDR Team’s approach for conducting field surveys to 

gather data for establishing a record of impact producing activities during the WTG 

installation and operations at the BIWF. 

The BIWF is America’s first offshore wind farm, and it is being constructed by Deepwater 

Wind (DWW) Block Island, LLC approximately 3 miles off the coast of Block Island, 

which is located approximately 16 miles south of the Rhode Island mainland (Figure 1). 

BIWF consists of five, 6-MW Alstom Haliade 150 wind turbine generators (WTGs), a 

submarine cable interconnecting the WTGs (hereafter referred to as Inter-Array Cable), 

and a 34.5-kilovolt (kV) transmission cable from the northernmost WTG to an 

interconnection point on Block Island (hereafter referred to as Export Cable). Once 

completed, the five turbines will produce 30-megawatts for Block Island residents, and 

the mainland will receive the additional power.

The construction of the facility began in July 2015, is occurring in a phased manner, and 

is anticipated to be completed towards the end of 2016. During the recently completed 

Phase I, 5 steel jacket foundations were installed over 18 weeks (from July 26 to October 

26, 2015). Phase II is scheduled to begin in June 2016 and will include installing power 

transmission cables and the WTGs on the foundations that were installed during Phase I. 

Following the completion of Phase II construction, operational testing is scheduled to 

occur towards the end of 2016.

Phase II will include the following major construction activities:

1. Sea2shore Cable Installation – which is scheduled to start in June 2016, by 

National Grid, and will include construction/installation of the following components 

2. Inter-array Cable: Submarine cable connecting the WTGs.

3. Export Cable: Cable connecting northern most WTG to Block Island.

4. Block Island Substation: This will be located in New Shoreham on Block Island, 

and it will include approximately 0.8 mile of underground cable from the beach to the 

new substation.

5. Block Island Transmission System (BITS): This includes a bi-directional 

approximately 20-mile submarine cable from Block Island to Scarborough State 
Real-Time Opportunity for Development of Environmental Observations (RODEO)

Work Execution Plan for Field Observations During Wind Turbine Foundation Installation

2 | June 25, 2016

Beach in Narragansett and 3.5 miles of underground cable from Scarborough State 

Beach to the Dillon’s Corner substation. The BITS will deliver power both to and from 

the Rhode Island mainland to Block Island.

6. Turbine Installation – This includes installation of turbine towers, blades, nacelles 

on the foundations that were constructed during Phase I, and it is scheduled to occur 

over 4 weeks in the summer of 2016. Each WTG consists of three sections. GE is 

currently manufacturing the lower sections at the Port of Providence facility. Final 

assembly of the turbine units will be completed at Quonset Point.

7. Turbine Operational Testing – WTG operational testing will be conducted during 

the fourth quarter of 2016. 

Per guidance from BOEM, monitoring and field observations proposed in the Field Plan 

and detailed in this WEP:

1. Do not duplicate or substitute for compliance monitoring that is required to be 

performed by the construction contractors,

2. Are compatible with scheduled construction 

3. Are designed for providing additional information necessary for BOEM analysts to 

fully analyze the scope and extent of environmental impacts that may result from the 

construction activities and provide data to improve the accuracy of models and 

analysis criteria used to establish current monitoring controls and mitigations.

Also, per guidance from BOEM, the approach presented in this WEP includes 

mechanisms for the following: 

 Ensuring that a process is in place for coordinating with other ongoing activities 

 Providing a process for coordination of the team’s efforts with the industry

 Providing sufficient safety procedures to protect personnel during monitoring 

activities.

1.1 Deliverables Schedule

The period of performance for this TO is 18 months from the date of award. The 

recording of the events during the installation of the wind turbine generators and acoustic 

recordings is expected to take place between August and December of 2016. Monitoring 

of initial operation will begin between August and December of 2016 following installation 

and monitoring for underwater sound, seabed vibration, and particle velocity will continue 

from initial operations for a period of 12 months. The benthic monitoring and sediment 

recovery activities will begin as soon as practicable after installation and be repeated 

during a period up to 12 months. Work products will be delivered per schedule shown in

2.0 Scope of Work

2.1 Monitoring Objectives 

The objective of this TO is to provide a record of impact producing activities and, where 

possible, quantify such activities during the construction of the facility, and to evaluate 

monitoring techniques. Specific technical objectives are as follows:

 Record the type and duration of visual activities that occur during the installation 

and operation of five wind turbine generators for BIWF including the size, type 

and number of vessels, the duration of activities, and other impact producing 

factors.

 Measure underwater sound generated by the operation of up to five wind turbine 

generators for BIWF.

 Measure the in air acoustic sound from operation of BIWF.

 Evaluate sediment disturbance and recovery from spud and anchor chain 

locations post-construction activities. 

 Conduct benthic monitoring around the turbine foundations.

 Evaluate acoustic data for all construction activities.

 Develop improvements for monitoring of marine mammals in vicinity of BIWF.

2.2 Industry Coordination 

As required by BOEM, this WEP includes mechanisms for ensuring industry coordination 

on an as needed basis. During the implementation of the TO, close coordination will be 

required with National Grid, DWW and TetraTech. The HDR Project Manager (PjM) will 

be primarily responsible for ensuring this coordination. As necessary, the PjM may 

assign a designee to support the coordination efforts.

Prior to commencing any fieldwork, efforts will be coordinated with the BOEM 

Contracting Officer Representative COR, DWW and/or National Grid. The HDR PjM (or 

his designee) will check in every morning with either DWW or the National Grid Manager 

to get an update on the activities planned for the day and their nature and duration. The 

PjM will share this information with all HDR Team members and monitoring personnel to 

ensure that data collection is conducted in real-time when the construction activities are 

actually in progress.

5 | June 25, 2016

2.3 Government-Furnished Information 

The following government-furnished information will facilitate finalization of the Draft Plan 

and subsequent implementation:

 Full details of construction methodology, especially:

- installation methodology (equipment, procedures and predicted duration)

- other activities (e.g., horizontal drilling)

 Timescales and program for each site

 Any planned mitigation or abatement

 Any specific requirements from BOEM acoustic modelers for data they wish to 

have for model verification

 Details of compliance monitoring required and proposed to be conducted by the 

construction contractors

 National Grid boring data along cable transect.

 Hydroacoustic data collected by Jasco as part of DWW’s mitigation plan.

2.4 Tasks

2.4.1 Wind Turbine Generator Installation 

Observations

Visual observations of construction activities associated with two turbine generators from 

the shoreline will be logged by the HDR Team during the turbine assembly. This phase is 

expected to last for approximately 5 weeks. The real-time data collected through visual 

monitoring will provide additional information necessary for BOEM’s evaluation of 

environmental effects of future facilities and generate data to improve the accuracy of 

models and analysis criteria employed to establish monitoring controls and mitigations.

Subtask 2.4.1.1 Onshore Visual Observations

The HDR team will provide visual monitoring during the installation, by placing a 

dedicated onshore observer to record the following from the Southeast Lighthouse: 

 Visibility of construction activities from shoreline

 The types of lighting used at the construction site and what can be seen from the 

shoreline

 Meteorological conditions that affect visibility from shore including humidity.
Real-Time Opportunity for Development of Environmental Observations (RODEO)

Work Execution Plan for Field Observations During Wind Turbine Foundation Installation

6 | June 25, 2016

Data will be recorded daily at early morning, mid-day, sunset, and during significant 

changes in meteorological conditions (rain, fog, etc.) during each day that construction 

takes place. The day’s first observation will be based on ferry schedule but should occur 

around 8:30 AM. Observations will include a set of photos taken from a fixed point, at the 

same angle, and using a constant zoom setting on the camera. Video recordings will be 

made as necessary to document unusual sightings or infrequent occurrences.

After observations are documented from the SE Lighthouse, the observer will transition 

to a to be determined location, and record activities occurring in Stand-by Area A. This 

area is located approximately 2 nautical miles to the west of Block Island and it will serve 

as a staging area for vessels or used during work stoppage due to weather or sea states. 

The exact location will be finalized during site reconnaissance immediately before 

installation activities begin, during mobilization of the team.

This dedicated onshore observer will be also be responsible for monitoring airborne 

sound pressure levels as described below in Section 2.4.1.3. In conjunction with sound 

pressure monitoring, the observer may also collect visual data from Mohegan Bluffs, 

Balls Point, or Pt. Judith on the mainland.

Task-Specific Assumptions

1. HDR costs are based on one staff staying 5 weeks (35 days at full per diem × 1 staff) 

+ (2 days of travel per diem × 1 staff) + (37 nights lodging × 1 staff).

2. Costs include purchase of Point Judith Ferry “books.” Each book contains 20 tickets 

at a discounted rate due to bulk purchase. The high speed ferry was selected (versus 

traditional) due to earlier morning departures in June.

3. Sea states along with weather (wind and rain) can change unexpectedly and may cut 

survey days and potential data collection short as a result. If data collection is 

hampered by sea state, HDR will immediately notify the COR and propose 

alternative approaches. 

Subtask 2.4.1.2 Offshore Visual Observations

A second dedicated observer will be located offshore on a boat adjacent to the WTG 

jackets during the turbine assembly and will record:

 Number, size, and type of construction vessels

 Size and location of deployed anchors 

 Number and nature of lighting used at the site 

 Type of construction activities being conducted and duration of each activity. 

Where possible, the observer will also record relevant information including incidental 

observations on the occurrence of marine species and other activities (fishing vessels, 

recreational vessels, etc.). The offshore observation location will be selected such that 

the monitoring vessel will not interfere with the construction activities or with transit of the 

construction vessels. Observations will also be made at least once per survey day of the 
Real-Time Opportunity for Development of Environmental Observations (RODEO)

Work Execution Plan for Field Observations During Wind Turbine Foundation Installation

7 | June 25, 2016

Stand by Area A. Construction activity observations will be recorded using an iPad with 

pre-formatted field logs.

HDR will utilize the charter vessel Hula Dog. A 27-foot-long center console outfitted with 

radar, GPS, and communications. The Hula Dog and its Captain, Matt King, provided a 

successful platform during Phase I monitoring. HDR team members will take the ferry 

over each day and board the Hula Dog on Block Island for monitoring. 

Task-Specific Assumptions

1. HDR costs are based on one staff staying 5 weeks (35 days at full per diem × 1 staff) 

+ (2 days of travel per diem × 1 staff) + (37 nights lodging × 1 staff).

2. The charter boat costs assume 35 days of monitoring. Should the schedule change, 

additional costs may be incurred if a different charter boat is required on short notice

or the number of monitoring days exceeds 35. 

3. Costs include purchase of Point Judith Ferry “books.” Each book contains 20 tickets 

at a discounted rate due to bulk purchase. The high speed ferry was selected (versus 

traditional) due to earlier morning departures in June.

4. Sea states along with weather (wind and rain) can change unexpectedly and may cut 

survey days and potential data collection short as a result. HDR will not be 

responsible for additional costs resulting from loss of effort caused by weather, 

and/or vessel mechanical failures.

Subtask 2.4.1.3 Airborne Sound Monitoring

Onshore Airborne Sound Monitoring

Prior to commencement of construction activities, The HDR monitoring team will mobilize 

to the site and undertake baseline noise monitoring on Block Island and the mainland, 

focusing on the Southeast Light (as used in August 2015) and Point Judith (mainland). 

An alternative monitoring location at Point Judith to the one used in 2015 will be 

identified during site recognizance due to the high background noise levels. Larson Davis 

LD831 sound level meters will be calibrated with field calibration devices and clocks will 

be synchronized. Baseline data will be captured on the day before construction begins

and outside of periods of construction noise.

The ability to capture airborne noise signal from the construction will be highly dependent 

on meteorological conditions, especially wind direction, and so under adverse sound 

propagation conditions, there is a chance that little to no signal from the works will be 

detected on land. Due to distances involved, it is likely that no sound is detected at Point 

Judith even in the event of ideal weather conditions. Where such a situation occurs, this 

will be logged and the measurements will not be repeated.

Monitoring is proposed for one turbine tower (approximately 5 days) unless they are 

curtailed due to persistent adverse weather conditions, or additional measurements 

taken in the event that additional measurements are clearly beneficial. It is expected that 

the towers and blades will arrive onsite on August 1st 2016 and the construction will

Work Execution Plan for Field Observations During Wind Turbine Foundation Installation

8 | June 25, 2016

commence two days later. Therefore the following airborne monitoring timeline is 

proposed:

 July 31. Mobilization and finalization of monitoring sites.

 August 1st to 2nd. Baseline monitoring, Southeast Light and Pt. Judith.

 August 3rd to 7

th. Construction monitoring.

 August 8

th

. Demobilize. 

Note the following:

No modelling has been incorporated into this task. Existing airborne noise models are 

typically designed for urban areas and generally over land. And in this particular 

situation, modelling would not influence our choice of monitoring locations due to the 

limited number of available sites to monitor from. However, if BOEM desires modelling 

of airborne noise over water from operation of the turbines, this can be researched

further and an implementation plan could be developed.

That the noise levels and propagation will be higher under downwind conditions and 

lower under upwind conditions is not in question, but it is the purpose of the 

measurements to quantify the real-life effect of these changing conditions. Irrespective of 

the results of monitoring, the number of available onshore monitoring locations on Block 

Island or the mainland with line of sight to the turbines, appropriate orientation to site, low 

background noise and accessibility are very limited and this is what will guide the siting 

of monitoring station(s). Offshore vessel-based monitoring will enable noise levels in 

multiple directions relative to the wind direction to be captured.

Task-Specific Assumptions

1. Monitoring is proposed for one turbine tower (approximately 5 days)

2. Three standby days have been factored into the budget to accommodate 

construction and weather delays.

3. HDR has budgeted 1 staff for 13 days to conduct onshore noise monitoring. 

Offshore Airborne Sound Monitoring

Airborne sound monitoring equipment will be set up on the survey vessel. The vessel 

proposed is URI’s R/V McMaster or R/V Shanna Rose. A Larson Davis LD831 sound 

level meter will be connected to a microphone on a 5/10m extension lead and a high 

performance windshield. The microphone will be fixed to the top of the wheelhouse on 

the vessel used for the underwater noise measurements, prior to departure from the 

harbor. Samples will be taken while construction is ongoing.

Offshore measurements will commence at the start of construction of the first tower 

installation, and end on completion of its final blade. Multiple airborne noise transects 

with varying wind conditions will be undertaken to ensure robust data is obtained.

The timeline for personnel presence on site will be as per the onshore program above

with the same assumption of standby days.

Subtask 2.4.1.4 B-roll and final vignette (construction & initial 

operation)

To help present the Block Island wind farm to the public, media and other constituents, 

Blue Land Media (BLM) will continue the work of capturing b-roll footage and interviews 

during the final construction and testing phases of the project. 

Filming will take place during 2, 4-day, trips. The first trip will coincide with the final 

stages of construction of the wind turbines to complete the visual story begun with the 

capture of the footage showing the installation of the transmission lines. The combined 

footage from the transmission line installation and final construction of the wind turbines 

will show the scope and general environment of the construction phases of the project. 

The second trip will coincide with HDR’s testing and monitoring work. When combined 

with the footage of the sediment monitoring completed during the transmission line 

installation, this footage will complete the monitoring story of the project. The footage will 

show not just how environmental impacts were studied to assess the impact of the 

construction phase, but how the ongoing environmental impacts of operation are being 

measured and monitored, including the future plans for marine mammal monitoring and 

ongoing study. 

In addition to the b-roll footage captured during these trips, interviews will be completed 

with key participants involved in the construction, monitoring and ongoing operation of 

the wind farm. At the conclusion of the filming trips, BLM will pull selected footage and 

interview comments and create libraries of the footage to be delivered to BOEM on hard 

drives (one master and one backup). This footage may be used for media outreach, 

educational projects, social media and other future uses.

Once all filming is completed, BLM will complete a short video vignette, approximately 5 

minutes in length, that will provide a thorough overview of the project, the outcomes and 

the careful monitoring and environmental impact assessments completed before, during 

and after construction. Since this is America’s first offshore wind farm, telling this story in 

a concise, accessible manner is particularly important to help media, the general public 

and other key constituencies understand both the process and assessment that has 

been a part of this historic project. The final video may be particularly useful in presenting 

and explaining future projects at public media and online.

The vignette will be completed with full color correction, professional narration, sound 

mix and mastering. It will be HD broadcast quality and will be provided in 1080HD and 

720HD H.264 video files for easy distribution.

2.4.2 Wind Turbine Generator Operations 

Observations

Wind turbine operations testing is schedule to occur in the fall of 2016. If there are delays 

in the construction and testing of the WTGs, the monitoring associated with the 

operations will be conducted as soon possible after the installation and testing is 

completed.

Subtask 2.4.2.1 Onshore Visual Observations

The HDR Team will conduct and log visual observations of operational activities from the 

shoreline during the turbine operational phase.

Initial operations visual observations will occur at three locations: Southeast Light House, 

Point Judith, and Brenton Point State Park. 

A single onshore observer will record the following from each of the three locations over 

a period of three weeks: 

 Visibility of operational activities from shoreline in the vicinity of the turbines.

 The types of lighting used at the operational site and what can be seen from the 

shoreline during night time monitoring.

 Meteorological conditions that affect visibility from shore including humidity.

The observer will spend a week (5 days) at each of the locations in order to capture 3 

days of monitoring under a variety of meteorological conditions. Data will be recorded 

daily at early morning, mid-day, late afternoon, and approximately 1 hour after sunset for 

a total of three days at each location following the beginning of initial operations. The 

observer will attempt to record observations during a variety of meteorological conditions. 

The observations will include a set of photos taken from a fixed point, at the same angle, 

and using a constant zoom setting on the camera. Video recordings will be made as 

necessary to document unusual sightings or infrequent occurrences. 

Nighttime observations will occur 1 hour after sunset to record and characterize types of 

lighting visible from shore. A Canon 7D-camera setup with a tripod to accommodate the 

required slow shutter speed necessary to capture images will be utilized to photograph 

operational activities. The last scheduled ferry departs Block Island at 7:30 PM; therefore 

observations from South East Lighthouse will require 1 week lodging on Block Island. 

Task-Specific Assumptions

1. HDR costs are based on one staff working at each of three locations for 5 days. (15

days at full per diem × 1 staff) + (2 days of travel per diem × 1 staff) + (16 nights 

lodging × one staff).

Subtask 2.4.2.2 Offshore Visual Observations

An HDR Team offshore observer will conduct one night time assessment to determine 

the maximum distance that lights can be observed. Still and video recordings shall be 

made at 7 distances from the turbines: 1 mile,3 miles, 5 miles, 10 miles, 20 miles, 25 

miles, and no longer visible

It is anticipated that the FAA warning lights will be visible to 25 miles and construction 

lights up to 5 miles. Measurements will be recorded on a clear night. Measurements shall 

be repeated, both moving away and towards the wind turbines. Meteorological conditions 

will be recorded. Where possible, the observer will also record relevant information 

including incidental observations on the occurrence of marine species and other activities 

(fishing vessels, recreational vessels, etc.).

HDR will utilize charter boat Hula Dog to conduct the nighttime monitoring. 

Task-Specific Assumptions

1. HDR costs are based on 1 staff staying 4 days (2 days at full per diem × 1 staff) + (2 

days of travel per diem × 1 staff) + (3 nights lodging × one staff).

Subtask 2.4.2.3 Airborne Sound Monitoring

2.4.2.3.1 Onshore Airborne Sound Monitoring

Sound level meters will be set up by the HDR Team to monitor the noise during wind 

turbine operation at the onshore locations noted below:

 Mohegan Bluffs (Southeast Light), at the same position used during the 

foundation installation in August 2015.

 Point Judith, although an alternative location to August 2015, less affected by 

wave/shore noise will be sought.

 Brenton Point State Park. This is a newly requested location and may well suffer 

from high background noise from a perimeter road and pedestrians on the park, 

and is over 20 miles away from the turbines. 

For the last two locations, attended monitors will be set up during the BIWF operational 

phase under ideal wind conditions (south west component) for one day. If no noise from 

the turbines can be detected, measurements at these locations will not be repeated. If 

noise is detected, sound will be recorded for a period of two days and a long-term 

monitoring program will be recommended.

The SLMs will have a specialized low frequency detection capability which will capture 

potential infrasound from the wind turbines, an issue which has been identified as a 

concern to the public from other onshore wind turbines.

A long term SLM will be set up and secured at the Southeast Light location. This will 

continuously monitor background noise conditions and capture meteorological 

conditions. It is proposed that the SLM will be remotely accessed and downloaded, and 

options from three suppliers are currently being investigated.

Task-Specific Assumptions

1. Onshore monitoring will be conducted by the HDR Team members conducting 

onshore visual monitoring, over the same time frame.

2.4.2.3.2 Offshore Airborne Sound Monitoring

Long-term offshore airborne noise monitoring is not currently feasible with existing 

technology, which is generally geared to onshore conditions. Therefore, the necessary 

airborne noise measurements will be captured offshore on the R/V McMaster or R/V 

Shanna Rose using a sound level meter with a microphone connected to an extension 

lead, and fixed with high performance windscreen to the top of the frame on the vessel. 

Airborne noise measurements will be taken under a variety of wind conditions: upwind, 

downwind and cross-wind of the operational turbines.

The weather forecast will be checked prior to mobilization to ensure that conditions are 

suitable such that calm conditions are avoided. It should be noted that it will not be 

possible to sample offshore airborne noise under high wind conditions for safety reasons. 

However, extraneous noise from waves in high seas is expected to dominate any noise 

directly from the turbine, making the turbine noise at sea level indistinguishable. In this 

scenario, noise measurements on shore, especially at the Southeast Light on the top of a 

cliff, may be of greatest benefit.

Noise characteristics, particularly in respect of volume and frequency, will be captured at 

relatively close range to the turbine (< 1000 m) with a focus on sampling varying wind 

speeds to identify changes that this causes. Measurements will be taken on transects to 

sample variations with range until noise from the turbine is inaudible. This includes noise 

from internal machinery as well as blade swish and any other noise produced by the 

operational turbine.

Airborne noise will be analyzed, as a minimum, in terms of LA90, LAeq and LCpeak.peak.

Task-Specific Assumptions

1. One standby day has been factored into the budget to accommodate construction 

and weather delays.

Subtask 2.4.2.4 Underwater Sound Monitoring – Operational 

Turbines

The HDR Team Member Subacoustech Environmental will deploy one fixed location 

hydrophone: at either 100 m from the location of one of the outer turbines or one 

centrally in between two of the turbines. URI will utilize one of the monitoring stations to 

sample the other location. 

The hydrophone is proposed to be an icListen HF, suspended by a floatation buoy from 

an anchor on the seabed. The clocks will be synchronized with other underwater and 

airborne sound monitoring equipment. This will monitor continuously over 3 months, after 

which it will be retrieved and downloaded. . The precise locations will be selected in 

consultation with HDR Team Member URI to ensure that the crossover between 

equipment set up in the vicinity of the turbines is as beneficial and complementary as 

possible, for example capturing data at equivalent distances both to the east and the 

west of the turbines.

Once the fixed monitoring station is deployed, HDR Team will travel to the foundation to 

be installed, as close as allowable by Deep Water Wind (DWW). It is understood that 

there are no restrictions provided no contact is made with the vessel and turbine or 

foundation itself. Transect measurements will be taken in a direction away from the 

turbine, moving outwards for as long as the turbine can no longer be detected above 

background noise. The bearings will be chosen in accordance with those taken during 

construction noise measurements in 2015, and will therefore include a transect towards 

Block Island, towards Point Judith and out to deep water to the east. During all 

measurements, all vessel equipment will be shut down, including engines, inverters and 

any other sound generating equipment. Measurements will be monitored by the surveyor 

using headphones to detect any unexpected, anomalous or erroneous signals.

Measurements will consist of two simultaneous subsea sound pressure samples using a 

vertical array at mid-water and at a depth of 1 meter above the seabed, using Reson 

TC4014 or Bruel & Kjaer 8016 hydrophones connected to proprietary variable-gain 

amplification and recording systems. A triaxial seabed vibration monitor (modified 

Vibrock transducer) will also be deployed at each location for as far as transmission 

through the seabed is detected. Daily conductivity, depth and temperature readings will 

be taken.

The data will be recorded in a raw data format that allows post processing in any metric 

currently used and detailed notes will be made to fully describe the situation in which the 

measurement was made for future detailed analysis. All data will be downloaded and 

backed up on a daily basis. The underwater sound pressure data will be processed to 

produce, as a minimum, dB re 1 μPa rms and peak levels. 

HDR Team Members URI/WHOI/MAI will participate in this task by supporting the efforts 

by Subacoustech to monitor the underwater acoustic environment near the Block Island 

Wind Farm. The equipment deployed will support this task in addition to the whale 

detection task below. The efforts in this task include:

 Deploy Geophysical Sled with 3D geophone on the seabed and a tetrahedral 

array of hydrophones about 1 m above the seabed. This system will be deployed 
Real-Time Opportunity for Development of Environmental Observations (RODEO)

Work Execution Plan for Field Observations During Wind Turbine Foundation Installation

15 | June 25, 2016

at a close range to the WTG #1 (range to be determined in consultation with the 

developer). The science objectives of these measurements will include: 

measurement of seabed vibration from turbine operation and measurements of 

acoustic pressure and particle velocity in the water column. This system will also 

be utilized as part of the whale detection and localization task described below. 

The tetrahedral array provides direction of arrival for signals such as whale 

vocalizations. 

 Design and deploy vertical and L-arrays for measurements of the distant turbine 

operation noise (range to the arrays to be determined as part of the design 

process). The arrays will be similar to those used in the summer of 2015 and are 

designed to be have low self-noise as demonstrated by the BIWF construction 

data analyzed to date. The arrays will also be used in the whale detection and 

localization task below. 

 Provide and deploy RBR CTD system used in the 2015 effort providing salinity, 

temperature, and depth data at stations to be determined. In addition, for long 

term monitoring of the sound speed, a number of thermistors will be mated with 

the vertical hydrophone arrays described below (e.g. the Seabird SBE56 

Temperature Logger) where we are deploying two vertical hydrophone arrays 

equipped with the SHRU data acquisition systems (similar to those deployed in 

2015) with upgraded atomic clocks that will enable accurate timing and therefore 

localization when combined with the DMON system.

Note the following:

The locations of the underwater noise monitors during wind farm operation are different 

than those used to monitor underwater noise during the construction program. Whereas 

a fixed monitoring distance of 750 m was used during the installation of turbine 

foundations, to be consistent with the bulk of data available from existing installations in 

Europe, for operational noise a position much closer to a turbine will be used, as well as 

one representative of multiple simultaneously operating turbines. The monitors deployed 

will sample multiple ranges and noise metrics, with minimal crossover.

A geophysical sled will be deployed sled equipped with the tetrahedral array of 

hydrophones (for the determination of particle velocity for fish and invertebrates effects 

studies) and 3D geophone at a range less than or equal to 100 m from the turbine (WTG

#3) to capture the noise levels near to the operational turbines. This siting of the sled will 

allow for the near field characterization including pressure, seabed vibration, and particle 

velocity. 

Vertical hydrophone array moorings and a horizontal hydrophone array will be deployed. 

One vertical array will be deployed at a range of 500 m and the other a range of 1000 m 

from WTG#3 aligned with the geophysical sled (the line perpendicular to the WTG array). 

This allows for the observation of the transition from near field to far field of the acoustic 

signals from the operating wind turbines. The horizontal array will be deployed co-located 

with 1000 m vertical array.

The HDR Team will deploy a long-term underwater sound pressure monitoring device in 

between two of the turbines to sample the ‘in-field’ noise emissions.

2.4.3 Benthic Monitoring

While long range and large scale changes in benthic conditions are not expected from 

the presence of the five turbines, localized disturbance near the foundation is expected 

and is poorly understood for this location. Alterations may occur due to the presence of 

the structures which provides substrate for marine organisms and resultant increase in 

the deposition of organic detrital material. 

Under this TO, benthic monitoring surveys shall be conducted at two turbine locations 

with different substrate types. Although the foundations were put in place during fall of 

2015, modifications of the seafloor should still be discernable and measured relative to 

the surrounding sediment habitat. Observations from the available European study are

of a “changing macrobenthic community” extending up to 50m from the scour protection 

boulders indicating the possibility of a long term shift in community composition, which 

may become spatially extended’ (Degraer et al., 20121). This information will form the 

basis for extrapolation to larger wind facilities. 

The purpose of the benthic monitoring is to assess temporal and spatial changes in 

benthic community abundance and diversity that may result from the potential sediment 

enrichment that is likely to occur in the vicinity of the BIWF WTGs during the operational 

phase. Roles and responsibilities of the benthic monitoring team members are described 

in Table 2

The proposed benthic monitoring and data analyses protocol is described below. This 

protocol incorporates BOEM’s habitat monitoring survey guidelines (as presented in 30 

CFR § 585) and integrates lessons learned from offshore wind farm benthic monitoring 

programs conducted in UK (MMO, 20142).

Subtask 2.4.3.1 Literature Review

Relevant and available scientific literature and pertinent project reports will be acquired 

and reviewed to crystallize current understanding of benthic ecological conditions within 

the BIWF Project Area and provide a wider context for interpretation of the survey 

findings. The findings of the literature review will also be used to clarify heterogeneity of 

seabed habitat and community types at the locations of the turbines to inform the turbine 

selection for the monitoring program. At a minimum, the following key documents will be 

reviewed:

 BIWF-BITS Environmental Report

 BIWF-BITS Benthic Survey Report 

 Geophysical (MBES and side scan sonar) data

 Others

Literature review findings and their significance and utility will be summarized and 

discussed in the benthic monitoring report.

Subtask 2.4.3.2 Study Design

Sediment samples will be collected and analyzed for benthic biota abundance and 

diversity at two (of the five) turbine locations. Sampling locations will be selected to 

represent different habitat types. Particle size distribution and organic content will also be 

analyzed in each sediment sample. The sampling ranges proposed are intended to 

provide adequate coverage of the anticipated spatial extents of effects based on prior 

observations such as those reported by Degraer et al., 2012. 

At each of the two turbine locations, seabed video and quantitative grab sediment 

samples will be collected at 20-, 50- and 100-meter distances from the base of the 

turbine foundation (Figure 1), subject to the presence and spread of scour protection 

material at the base of the foundation and the presence of inter-array cables and in 

collaboration with DWW. 

In addition, two reference areas, located outside of the predicted influences of the BIWF 

activities and comparable in substrate and depth conditions, will also be selected and 

surveyed under this task. Data from the reference areas will allow assessment of benthic 

change attributable to the operation of the wind farm against the natural variation.

At each of the four locations, sample stations will be orientated in line with the dominant 

tidal current flow and perpendicular to the current. The hypothesis tested in this instance

will relate to the presence of a gradient of enrichment effects along the axis of the 

dominant tidal flow with minimal or no effects occurring on the seabed perpendicular to 

the direction of current flow. The direction of the flow of the principal current at each 

turbine will be established from AWAC monitoring data that is being collected under a 

separate task.

Six sample stations will be selected at each turbine location; each station will be sampled 

in triplicate to increase statistical rigor. Thus, 18 samples will be collected at each turbine 

location for a total of 36 samples between the two turbines.

Three sample stations will be selected at each reference site; each station will be 

sampled in triplicate to increase statistical rigor. Thus, 9 samples will be collected at each 

reference site for a total of 18 samples between the two reference sites.

Finally, at each of the two turbine and the two reference stations, a designated QC 

sample will be collected and processed. The four QC samples will be subjected to 

taxonomic analyses by an independent expert. 

Thus a total of 36 (2 turbine stations) + 18 (2 reference stations) + 4 QC (2 turbine and 2 

reference stations) = 58 samples will be collected and analyzed during each survey.

Monitoring locations and sampling stations will be selected based on literature review 

findings and will be confirmed in the field through review of seabed video prior to sample 

collection.

Subtask 2.4.3.3 Monitoring Methodology

At each sampling site, drop down video will be undertaken using a digital video/stills 

camera mounted in a suitable frame. It is anticipated that underwater visibility will be 

suitable for a standard video frame to be used based on previous similar seabed video 

surveys at Block Island Wind Farm. Seabed habitat types and epibenthic communities 

will be recorded throughout the duration of the seabed video deployment together with 

any initial observations. The duration of the seabed video surveillance at each station will 

be a minimum of 5 minutes although this will be extended where necessary to ensure 

that all features observed can be confidently described in terms of their spatial extent, 

composition and characterizing biology. 

Representative photographic stills of the seabed will also be taken (minimum 5 georeferenced photographs per deployment). Distance lasers will be mounted on the video 

frame to allow for scaling of sediment size classes and species.

Positions for the video survey will be recorded at the beginning and the end of each drop, 

with the position of the video throughout the video drop overlain on the video footage to 

ensure accurate geo-referencing. The initial deployment of the drop down video at each 

sample station will enable assessment of the seabed habitat in terms of local 

heterogeneity and key epibenthos species. 

Following recovery of the seabed video, the Smith-Mcintyre grab sampler, which covers 

approximately 620 cm2 area, will be deployed at each sample station. A Go-Pro video 

camera will be attached to the sampler in order to document the nature of the seabed at 

the exact location where the grab sediment sample is collected. Upon recovery of the 

sample, the sediment within the grab bucket will be viewed in order to assess whether 

the sample is acceptable (i.e. has not been subject to partial washout during retrieval, 

and is of sufficient volume relating to depth of bite). A measure of the sediment redox 

potential will be taken and recorded. The sample will be released into a hopper. An 

assessment of sample volume (expressed in liters) will then be made and a visual 

description recorded. A photograph of the sediment will be taken prior to any sample 

processing. Any conspicuous sediment features and obvious fauna will be recorded.

A sub-sample for particle size distribution analysis and organic content will be transferred 

into a pre-labelled heavy duty quart-sized Ziplock plastic bag and sealed to ensure no 

loss of fines. Sediment samples will be stored at 40C up to a maximum of 28 days prior 

to analysis. 

The remaining sediment sample will be sieved on a 1mm aperture mesh sieve to remove 

the finer sediment fractions. The contents of the sieve will be transferred into a prelabelled bucket with internal label and fixed on-site using 4% buffered saline formalin 

solution. Stain will be added at this stage, as appropriate.

Monitoring Frequency

One round of benthic monitoring surveys will be conducted under this TO. Note that it is 

expected that any sediment enrichment and benthic modification will develop over a 

comparatively long time and only after mature fouling communities have developed on 

the turbines and foundations. Therefore, it is strongly recommended that benthic 
Real-Time Opportunity for Development of Environmental Observations (RODEO)

Work Execution Plan for Field Observations During Wind Turbine Foundation Installation

20 | June 25, 2016

monitoring continue in the future at pre-defined intervals (1, 3, 5, and 10 years post 

operations).

During the repeat monitoring survey(s), it will important to re-locate the sample stations 

with a high degree of accuracy so that repeat samples are collected at the same point 

along the gradient of change for comparison between monitoring occasions. Differential 

GPS (dGPS) with navigational layback with accuracy of 1 – 3 m should be used for 

position fixing and finding during the future monitoring events.

Also, the repeat survey(s) should be performed at the same time of year as the initial 

sampling proposed under this TO to negate the effects of seasonal variation in benthic 

community composition.

Subtask 2.4.3.4 Survey Mobilization

All necessary equipment and personnel will be mobilized at the URI Bay Campus and 

loaded on the R/V Shanna Rose at Point Judith Pond on the South Coast of Rhode 

Island. It is anticipated that mobilization to the survey locations will require about 

approximately 4 hours. Transit time to the survey area is estimated at about one hour.

Subtask 2.4.3.5 Field Sampling

A field crew of four people including a captain, a technician and two graduate students 

from URI will be utilized for the underwater video and grab sampling field survey. The 

first (initial) survey is planned to be conducted during October/November 2016 time 

frame and is expected to last over approximately 3 days. The port of operations for the 

duration of the monitoring study will be Point Judith Pond. All sampling survey will be 

conducted using the vessel R/V Shanna Rose. This vessel has been recently used 

during acoustic surveys at Block Island and is therefore suitable for site and sea 

conditions.

Subtask 2.4.3.6 Taxonomic Analyses

Macrofaunal grab samples will be re-sieved over a 1mm mesh to remove all remaining 

fine sediment and fixative. Fauna will be sorted from the sediment by elutriation and 

subsequent examination upon a white tray, with the resultant extracted sediment then 

sorted by hand under a binocular microscope. Residual sediment fractions will be 

retained following sorting for future Quality Control (QC) auditing.

Macro-invertebrates collected from the grab samples will be identified to species level, 

where possible, and enumerated. Colonial, encrusting epifaunal species will also be 

identified to species level where possible and were given a P (present) value.

Faunal biomass analysis will be based on a wet-biota method with estimates of ash-free 

dry weight. Faunal samples will be separated into infaunal and epifaunal species, the 

former only being included in the analysis. The retained infauna will then be separated 

into the following phyla, and weighed to 0.0001g:

 Polychaeta

 Crustacea
Real-Time Opportunity for Development of Environmental Observations (RODEO)

Work Execution Plan for Field Observations During Wind Turbine Foundation Installation

21 | June 25, 2016

 Echinodermata

 Mollusca

 Others

The primary macrofaunal analysis of 54 samples will be conducted by taxonomic 

specialists at the Ecological Consulting Organization. Macrofaunal analyses of the 4 

QA/QC samples will be conducted by Sheldon Pratt, a local expert on the staff at URI. 

Results from the two separate analyses will be compared to each others to provide 

analytical quality control.

Subtask 2.4.3.7 Particle Size Distribution

Sediment samples collected in the field will be analyzed for particle size distribution. 

Particle sizing will be undertaken via a sieve series corresponding to half phi units and a 

Rptap system. Laser diffraction techniques using a Malvern system shall be used for the 

further analysis of the fines (<63m) fraction of the sediment where these constitute 5% or 

greater by weight of the sample.

Subtask 2.4.3.8 Sediment Chemistry

Sub-samples of seabed sediment will be analyzed for organic matter content. A muffle 

furnace will be used to for the organic matter content determination following the LossOn-Ignition method of Dean (19743

).

Subtask 2.4.3.9 Video Documentation

The development of stereocamera systems deployed in Lagrangian float drifters (Roman 

et.al.,20114) provide very high quality images that can be captured and mosaiced for 

complete coverage imaging of bottom type and epibenthic community. The camera float 

can be deployed during the conventional video and grab sampling exercise and 

recovered after a ~2 hour deployment. It gathers improved video data but does not add 

to field time.

Video footage will be analyzed to describe the epibenthic communities, and seabed 

habitat types. Should potential geogenic reef be recorded, an estimate of the percentage 

of cobbles, boulders and bedrock throughout the drop down video transect will be 

undertaken, together with elevation, extent and species composition.

Subtask 2.4.3.10 Data Analyses

Data drawn from the faunal and sediment analyses will be analyzed to describe 

community and seabed sediment structure and distribution and to elucidate relationships 

between faunal assemblages and physical and chemical variables. The approach will

follow that used recently for habitat mapping in the field area by LaFrance et al (2014)5. 

In short, side scan sonar imaging will be used in conjunction with the benthic biology and 

video data to produce fine-scale habitat maps of the of the study area in CMECS format. 

Biological descriptors of the community (abundance of individuals, biomass, Richness, 

Dominance and Shannon's diversity) will be calculated. 

The PRIMER suite of statistical routines shall be employed to investigate community 

structure and relationships with abiotic factors employing non parametric Multidimensional Scaling (nMDS), BIOENV and SIMPER as well as ANOVA and ANOSIM to 

detect significant differences between the different treatment and sampling campaigns 

(Clarke & Warwick, 20016).

The hypotheses that will be tested include:

 Seabed sediments in close proximity to offshore wind farm turbine foundations 

will become organically enriched resulting in modified benthic invertebrate 

communities over time compared to reference conditions. 

 A gradient of organic enrichment and benthic community modification will occur 

with the greatest modifications, relative to reference conditions, occurring with 

decreasing distance from the turbine foundations. 

 Effect gradients will be aligned with the direction of the principal tidal axes 

dominating the wind farm site.

The variables that will be measured include:

 Sediment organic carbon content

 Sediment particle size distribution 

 Depth

 Numbers of macrobenthic species (S)

 Numbers of macrobenthic individuals (A)

 Macrobenthic biomass (B)

 Habitat and community classification

Derived univariate and multivariate variables will be drawn from the PRIMER v6 package 

of statistical routines (Clarke & Warwick, 2001). Statistical hypothesis testing, (i.e. 

ANOVA) will also be employed to detect significant difference between the different 

treatment and reference sample locations. 

To the best of our knowledge, the only prior use of this type of sampling design has been 

at the Thorntonbank offshore wind farm in the Belgian sector of the North Sea (Degraer 

et al., 2012). The limited monitoring of this type highlights the very restricted information 

available on local-scale effects on benthos and the value of the current opportunity to fill 

this important data gap under the RODEO initiative.

Radial sampling is the proposed as the preferred design to test the hypothesized 

gradient effects. The design is particularly recommended to fill current knowledge gaps 

regarding local-scale effects of offshore wind farm operation on benthic ecology.

Subtask 2.4.3.11 Reporting

For each survey, two work products will be prepared. The first will be a (draft and final) 

technical report and the second will be a manuscript for publication in a national peerreviewed journal. 

In both work products, the focus will be on documenting possible changes in the CMECS 

biotope classification around the turbine structures associated with any organic 

enrichment of the local sediments and "reef effects" due to colonization of the hard 

substrates provided by the foundation structures. In some instances, the changes to 

benthic community structure may be beneficial by providing an enhanced epifaunal food 

source, whereas in others it may be detrimental, e.g. colonization by invasive tunicate 

species or change in sediment chemistry. Enrichment and reef effects may take longer 

than one year to develop. Recommendations for extended study will be discussed and 

will consider DWW’s monitoring commitments to optimize future sampling efforts. The 

report will also include discussion on the performance and possible future utility of the 

stereo-camera/floater system in offshore wind farm monitoring.

Task-Specific Assumptions

1. One round of sediment sample collection and processing will be conducted under 

this task.

2. Monitoring locations and sampling stations will be selected based on literature review 

findings and will be confirmed in the field through review of seabed video prior to 

sample collection.

3. A total of 36 (2 turbine stations) + 18 (2 reference stations) + 4 QC (2 turbine and 2 

reference stations) = 58 samples will be collected and analyzed under this task. 

4. Sediment sampling is expected to occur over a 3-day period; this includes 

approximately 4 hours for mobilization and two hours of round trip transit time each 

day.

2.4.4 Evaluation of Acoustic Data (OPTIONAL)

The HDR Team (including URI, WHOI, MAI and Subacoustech) will analyze the data 

collected during the pile driving activities by DWW at the BIWF in 2015. The hydrophone 

and geophone calibrations will be incorporated into the calculation of acoustic field and 

particle velocity at all sensors. Based on the construction log, the received acoustic 

signatures will be correlated with the appropriate pile and the hammer strike. The main 

focus of the effort will be on the data from the geophysical sled consisting of the 3-axis 

geophone and the tetrahedral hydrophone array. 

The team will also try to estimate particle velocities on the seafloor (from the 3-axis 

geophone data) and in water (approximately 1 m from the seafloor using the data from 

the tetrahedral array). Modeling and data analysis efforts of various team members will 

be coordinated to interpret the spatial variation of the levels measured by different 

systems (URI, MAI and WHOI). Available environmental information will be collected and 

consolidated to facilitate the modeling efforts. These data include sound speed profiles 

from CTD data, bathymetry and geoacoustic information. The major tasks are:

1. Pile schedule, check pile rake, construct log of pile number and leg number vs. 

time: Analyze the acoustic and particle velocity data and correlate it with the pile 

driving schedule and appropriate hammer impact on individual piles. Tabulate the 

pile rake associated with the acoustic signatures addressing the potential cause of 

sound pressure level variation with rake. 

2. Incorporate the exact calibration of acoustic and particle velocity sensors:

Extract the correct absolute levels. Based on the hammer type, the difference in the 

levels of noise radiated from hammer impacts will be investigated. Background noise 

will be characterized and compared with the data collected during the SAMP studies. 

Kurtosis of the data will be calculated to investigate the changes in this metric as a 

function of range and pile rake.

3. Environmental data coordination: collect and consolidate the available 

environmental information to facilitate the 3-D modeling of the acoustic field. These 

data include sound speed profiles from CTD data, bathymetry and geoacoustic 

information. Environmental data from sources such as Ocean Special Area 

Management Plan (O-SAMP), other surveys and coring from the location, site 

characterization by construction contractors, etc. will also be gathered.

4. Coordinate the 3-D modeling efforts: Coordination will occur between URI, Sandia 

Laboratory, WHOI, and MAI. The pile rake information from task 1 and the 

environmental data from task 3 will be inputs to the 3-D models. The underwater 

soundscape will be created by assimilating the data and model results. The effect of 

water depth, bathymetry, temperature, sea state, sediment type on the sound 

propagation will be investigated using the model. Estimates of the noise levels at 750 

m and comparison of this with BIWF measurements taken by Tim Mason at 

Subacoustech and with European measurements from comparable water depths, 

pile diameters and hammer energies will be accomplished. Sandia has 

computational capability along with both commercial and in-house modeling tools 
Real-Time Opportunity for Development of Environmental Observations (RODEO)

25 | June 25, 2016

applicable to this problem. A subcontract between URI and Sandia for assisting our 

team in developing the 3D model including mentoring a graduate student will be 

used. The model will be validated by comparison to measured data and WHOI 3D 

models.

5. Particle velocity on the seabed and in water: Particle velocity calculation using 

the data from 3-axis geophone and acoustic data from the tetrahedral array will be 

accomplished. It is recommended that calculation be done in coordination with Dr. 

Steve Crocker at the Naval Undersea Warfare Center (NUWC) due to the scarcity of 

expertise in this area of science. To accomplish this coordination, BOEM would need 

to establish a mechanism such as the use of an interagency agreement with NUWC 

tasking their agency to provide technical input and review for this calculation. 

6. Actual sound pattern: Coordinate an effort to determine the actual sound pattern at 

the various locations comparing the background noise 30 minutes before the 

impulsive pile driving signals, followed by an hour of background noise level 

measurements. The analysis will include the energy measured at the piles by DWW 

to understand the effect of pile energy to received levels. This will be repeated for all 

available pile driving events.

Note the following:

Analysis of the pile driving data collected in the summer and fall 0f 2015 will be broken 

down between the organizations based on their in-house expertise. In particular, the 

towed array data was a focused effort of Marine Acoustics, Inc. and that data analysis 

will be led by MAI with support from the other organizations. The preliminary analysis of 

vertical line array data (SHRUs) from the same period will be led by WHOI. WHOI had 

the SHRURead software for signal extraction, cataloguing and archive. 

The follow on analysis on the extracted signals will be done the other organizations 

which have specific focus. For example, MAI and WHOI are particularly interested in the 

observations of pile driving and marine mammal vocalizations. The value of signal 

extraction, cataloging and archiving provides a cost effective launch pad for detailed 

analyses including graduate theses and dissertations. URI will coordinate the team 

efforts in addition to participating in the data analyses.

Also, the Team will provide frequency-weighted analysis of the data in accordance with 

NOAA's guidelines. In particular, the team will compute 0-to-peak unweighted SPL and 

weighted SEL estimates for the pile driving signals measured at the various instruments.

Task-Specific Assumptions

1. Three months of analysis are included in the cost estimate. 

2. This is an optional task to be performed only if additional funding is authorized by 

BOEM.

2.4.5 Whale Detection for Marine Mammal 

Monitoring (OPTIONAL)

Passive acoustic monitoring has become a standard methodology for assessing the 

occurrence and distribution of marine mammals; however, surprisingly little research has 

been conducted on the detection range of different species’ vocalizations, and how that 

detection range varies with environmental conditions (e.g., ocean conditions, water 

depth, sediment type), signal type, passive acoustic monitoring system, and platform 

(e.g., moored buoy, autonomous underwater vehicle). To effectively use passive 

acoustics to monitor marine mammals, an understanding of the area over which the 

monitoring system can detect each species of interest is absolutely critical.

Using HDR Team Members URI, WHOI and MAI, a cost-effective plan that is 

scientifically sound and produces all the required data to detect, classify and localize 

(DCL) marine mammals including right whales, humpback whales and fin whales within 

the potential zone of influence of the operating wind turbines was developed. One option 

by the team involved the fabrication and deployment of a DMON buoy similar to that 

already in place on operating off of Nomans Land, Massachusetts (Figure 2). The DMON 

buoy would provide real time detection and classification of these whales. The current 

system could not localize because of the design limitations in the system. Therefore, with 

importance of localization with accurate distance estimation to the animals, the team will 

use the existing DMON buoy for initial detection and classification. 

In addition to this DMON system, we will deploy two vertical hydrophone arrays equipped 

with the SHRU data acquisition systems (similar to those deployed in 2015) with 

upgraded atomic clocks that will enable accurate timing and therefore localization when 

combined with the DMON system. In addition, we will deploy an L-shaped hydrophone 

array with both a vertical and horizontal sections. The vertical component would be in the 

water column and the horizontal component would be on the seafloor. The combination

of the existing DMON, two SHRU vertical hydrophone arrays and the L-shaped 

hydrophone array along with the tetrahedral array on the sled very near one of the wind 

turbine structure provides the redundancy in measurements needed to reliably detect, 

classify and localize these whales. 

All of the assets deployed as part of this project have dual capability to monitor the wind 

turbine noise as well as the whale DCL effort. The systems should be deployed for 6 

weeks at a time, ideally in three separate deployments over the next 12 months. 

However, due to budget constraints only one deployment over six weeks is possible and 

has been included in the cost estimate.

These are autonomous data recording systems that will provide acoustic signals upon 

recovery after each deployment. An option, if requested by BOEM, is that a new DMON 

system can be fabricated and deployed. This system could be integrated in the design 

described above enhancing results.

Figure 2: Spectrogram of the acoustic data recorded on the 15-km vertical array 

mooring on November 4, 2015 showing fin whale calls centered at 20 Hz. 

Note: Fin whale calls (indicated by the vertical red lines about every 10 seconds) were also detected on 

the same day by the WHOI DMON system near Nomans Land Island, Massachusetts shown at 

http://dcs.whoi.edu/nomans0315/nomans0315.shtml.

Task Methodology

The HDR Team will investigate the potential for real-time detection and tracking of 

marine mammals using the same SHRU moorings described above. The equipment 

proposed for this task includes two SHRU moorings and the tetrahedral array onboard 

the geophysical sled along with a WHOI L-array (an array with both a horizontal leg and 

a vertical leg). This equipment is already on hand and can be deployed at relatively low 

cost. 

In addition, the existing DMON system off Nomans Land, Massachusetts will be utilized 

in this task. With this DMON system, the two SHRU moorings, the tetrahedral array and 

the WHOI L-array, we can study the detection probabilities for the various marine 

species including fin whales, humpback whales, and right whales. 
Real-Time Opportunity for Development of Environmental Observations (RODEO)

Work Execution Plan for Field Observations During Wind Turbine Foundation Installation

28 | June 25, 2016

The performance of the system in localizing vocalizing whales will be assessed with 

playback experiments using a towed acoustic source such as a J-15-3 which can 

transmit acoustic signals as low as 50 Hz. We will also perform playback experiments to 

assess system performance. The SHRUs will be upgraded with high precision atomic 

clocks for this work and a synchronization source (with source level of about 160 dB re 1 

Pa at 1 m) will be deployed in the region to align the systems' clocks. The uncertainty 

associated with whale localizations will be evaluated. The deployments of these systems 

should be done in 6-week periods, ideally with at three deployments, one in the fall of 

2016 and two in winter and spring of 2017 but due to budgetary constraints only a single 

deployment in fall of 2016 is included in the cost estimate. Other deployments in the 

winter, spring and summer 2017 could be added with sufficient resources. 

Any permits required for the deployment of the moored synchronization source and 

towed playback source will be acquired by the HDR team in consultation with the BOEM. 

The sources being employed have source levels below 170 dB re 1 Pa at 1 m. 

Therefore, we foresee no potential problems with getting any required permits and likely 

will get Finding of No Significant Impact (FONSI) from the National Marine Fisheries 

Service Office of Protected Species.

Note the following:

1. The HDR Team will use array processing to enhance detection of the marine 

mammal vocalizations against ambient noise from shipping, wind, etc. and the 

noise from the Block Island Wind Farm. The horizontal array will have 8 

hydrophones and will be an array gain of 9 dB. The vertical arrays of 4 phones 

each provide 6 dB each of array gain. The design of system of vertical arrays and 

a horizontal array was chosen to maximize the marine mammal detection 

probabilities at a reasonable cost. Alternatives were considered including a new 

real-time DMON buoy but this variant was not chosen for this demonstration due 

to its cost and time constraints in getting the system ready for the Block Island 

Wind Farm operation expected for the fall of 2016.

2. Detections of marine mammals on the vertical line arrays and horizontal line 

array will used to estimate time-varying positions of these animals. The data 

published online from the existing DMON system off Nomans Land will be used 

to validate the detections. We are not proposing to deploy another DMON 

system.

3. The horizontal line array has directivity and can simultaneously detect the 

vocalizing marine mammals and the monitor the noise radiated from the 

operating wind turbines. Our objective for this work is to optimize the resources 

for this dual application. The existing DMON buoy data available online will be 

used to validate the marine mammal detections on the horizontal and vertical 

arrays. The capability for simultaneous wind turbine noise monitoring and marine 

mammal passive tracking will provide the community with a demonstrated tool 

that enhances the study of any potential effects of offshore renewable energy 

installations.
