EK60 Water Column Sonar Data Collected During DY0801

Echo Integration-Trawl Surveys of Walleye Pollock in the Shumagin Islands and Sanak Trough areas of the Gulf of Alaska, 6-15 February, 2008 (DY2008-01). The Midwater Assessment and Conservation Engineering (MACE) program of NOAA National Marine Fisheries Service (NMFS), Alaska Fisheries Science Center (AFSC) conducted acoustic-trawl (AT) stock assessment surveys in the Shumagin Islands and Sanak Trough areas of the Gulf of Alaska (GOA) during the winter of 2008 to estimate the distribution and abundance of walleye pollock (Theragra chalcogramma). This cruise was also used as an opportunity to compare results from acoustic-trawl surveys conducted simultaneously between NOAA Ships Oscar Dyson and Miller Freeman. This survey was conducted onboard NOAA Ship Oscar Dyson, departing from Kodiak, Alaska on 6 February and arriving in Dutch Harbor, Alaska on 15 February. A calibration of the echosounder system was conducted in Three Saints Bay, Kodiak Island, Alaska on 6 February. Both vessels (Freeman accompanying the Dyson) conducted the Shumagin Islands survey (including Shumagin Trough, Stepovak Bay, Renshaw Point, and Unga Strait) 7-12 February. The vessels conducted the survey of Sanak Trough 12-13 February. The experimental intervessel comparison work required that the vessels travel side-by-side along the survey transects at a separation distance of 0.5 nm, and at other times following each other at a distance of 1.0 nm along shorter transects. The intervessel comparison was designed to minimally impact efforts to complete the survey with the Miller Freeman as the primary survey vessel. A calibration of the Dyson echosounder system was conducted at the end of the survey in Captains Bay, Dutch Harbor, Alaska on 15 February. The Dyson arrived in Dutch Harbor, Alaska on 15 February, ending the cruise. The Dyson is a 64 meter fisheries research stern trawler equipped with acoustic and oceanographic instrumentation. The primary acoustic echosounder system installed on the Dyson is a Simrad EK60 scientific split beam echosounder utilizing five frequencies (18, 38, 70, 120, and 200 kHz).

EK60 Water Column Sonar Data Collected During NF-10-03-USVI

NF -10-03-USVI Characterization of Seafloor Habitats of the U.S. Caribbean (EK60). The Center for Coastal Monitoring and Assessment (CCMA) will be conducting the eighth year of an ongoing scientific research mission onboard NOAA Ship Nancy Foster funded by NOAAâs Coral Reef Conservation Program. The purpose of the cruise will be to collect swath bathymetry and acoustical backscatter, as well as fishery acoustics data in high priority areas in the U.S. Caribbean. Scientists will collect high resolution multibeam and acoustic fisheries data in midwater depths approximately 30 to 1000 meters so as to continue to characterize seafloor habitats within all U.S. States, Territories, and Commonwealths. The objective of this project is to collect a multibeam bathymetry dataset with 100% seafloor ensonification, along with multibeam backscatter suitable for seafloor characterization. Fishery acoustics data will be collected to characterize broad-scale fish abundance, biomass, and utilization patterns, as well as to locate and document fish spawning aggregations. Multibeam data will be collected to conform to IHO Order 1 (less than 100m) and Order 2 (>100m) accuracy standards. The strategies developed for each survey area will take into account the minimum depths, general bathymetry, and time allotment. The delineation and identification of seafloor habitats will be assisted by the use of a moderatedepth Remotely Operated Vehicle (ROV) and drop camera. The vehicle has video and frame camera capability to depths of 300 meters and will be used to point sampling within areas mapped during this mission.

EK60 Water Column Sonar Data Collected During FR0904

Sardine Biomass Survey. Eighty four primary stations were plotted on the survey track with an approximate spacing of 20 - 40 nautical miles. At each station the following activities were performed:

a. Deployment of a Seabird CTD down to 200 meters, bottom depth permitting. The self-contained CTD collected depth, temperature, conductivity and oxygen data.

b. Standard Pairovet cast down to 70 meters depth deployed concurrently with the CUFES system.

c. A CalBOBL (CalCOFI Bongo) standard oblique plankton tow with 300 meters of wire out, depth permitting, using paired 505 Âµm mesh nets with 71 cm diameter openings. The technical requirements for this tow were: Descent wire rate of 50 meters per minute, held at terminal depth for 30 seconds and retrieved at a wire rate of 20
meters per minute. All tows with ascending wire angles lower than 38Â° or higher than 51Â° in the final 100 meters of wire were repeated. Additionally, a 45Â° wire angle was closely maintained during the ascent and descent of the net frame.

d. Standard meteorological data including SST, wind speed and direction, wave height and direction, cloud cover, relative humidity, air temperature and barometric pressure.

e. During all transits between stations continuous measurements were made of pelagic fish eggs (CUFES) and acoustic targets using the EK-60.

f. A 264 Nordic Rope Trawl with 3.0 meterÂ² foam core doors was towed on the surface at night for a duration of thirty minutes. The 264 NRT was modified for surface trawling with Polyform floats attached to the head rope and trawl wings. The trawls have been modified with marine mammal excluder devices (MMED) to eliminate any possibility of catching marine mammals. Although the probability was very low that the gear being lowered
into the water on station will interact with any marine mammals, a marine mammal watch was initiated 30 minutes before arriving on station. If any marine mammals were detected in the area,
operations were suspended and the station location moved.

ME70 Water Column Sonar Data Collected During SH1005

Shimada Seamount Mapping. The ME70 survey was conducted with repeated coverage of the shallow part of the seamount, operating the ME70 in two  configurations. One configuration was optimized for water-column and seabed mapping to a range of about 300 m, and the other for seabed mapping to a range of 500 m. 

Initially, the ship followed the 500-m contour around the bank to define its spatial extent. Survey waypoints were revised to match the extent, and the ship then followed the parallel survey lines over the top of the bank.

The ME70 and EK60s were operated and recorded to ranges of 1000 m. The operational and recorded range for the initial transit around the seamount o enable seabed detections to 500 m for ME70 beams steered near 45 deg. angles from vertical.

Triggering was synchronous, with the ME70 trigger set as master controlling the EK60 trigger and the delay set to 0-ms.

ME70 was operated at high power. Motion compensation for the ME70 was active with motion data supplied from an Applanix POSMV model MV V4, via serial port. Position data to the ME70 and EK60 were from a MX Marine MX 420 Navigation System GPS with differential correction. Data were recorded in Simrad raw format (.raw files) for the ME70 and EK60.
