ME70 Water Column Sonar Data Collected During DY1302

Shumagin Islands Acoustic-Trawl Survey of Walleye Pollock (DY1302, ME70). The Midwater Assessment and Conservation Engineering (MACE) program of NOAA's National Marine Fisheries Service, Alaska Fisheries Science Center (AFSC), conducted an acoustic-trawl (AT) stock assessment survey in the Gulf of Alaska (GOA) during late winter of 2013 to estimate the distribution and abundance of walleye pollock (Gadus chalcogrammus). The survey areas included the Shumagin Islands area (consisting of Shumagin Trough, Stepovak Bay, Renshaw Point, Unga Strait, and West Nagai Strait), Sanak Trough, and Morzhovoi Bay (February 26 to March 3, 2013). The survey was conducted aboard NOAA Ship Oscar Dyson, a 64 meter stern trawler equipped with acoustic and oceanographic instrumentation in addition to biological sampling capabilities. The primary instrumentation for the survey was a Simrad EK60 split-beam echosounder system utilizing five frequencies (18, 38, 70, 120, and 200 kHz) and a Simrad ME70 multibeam echosounder, with the ME70 trigger synchronized to the EK60 system.

ME70 Water Column Sonar Data Collected During PC1802

South Atlantic Deep-Water Marine Protected Areas and Oculina Experimental Closed Area: Characterization of Benthic Habitat and Fauna. The primary objectives of the cruise were to gather additional data on habitat and fish assemblages
within and adjacent to six of the South Atlantic Grouper/Tilefish MPAs and inside the OECA as part of a long term sampling program to document changes in these areas before and after implementation of fishing restrictions.  Efficacy testing of this management tool will aid fishery managers in future use of area restrictions for the protection of valuable habitat and fishery resources.  Specific objectives included:
o Conduct remote operated vehicle (ROV) transect surveys of habitat and fish assemblages
o Conduct total water column CTD profiles for each location
o Conduct multibeam mapping with Piscesâ ME-70 system inside and outside existing
MPAs to locate potential ROV survey sites as well as to continue assembly of a comprehensive bathymetric map of the entire outer continental shelf margin of the southeastern US.

EK60 Water Column Sonar Data Collected During AL0401

NEFSC 2004 Winter Bottom Trawl Survey (AL0401, EK500). The NEFSC bottom trawl survey is a fisheries independent, multi-species survey that provides the primary scientific data for fisheries assessments in the U.S. mid-Atlantic and New England regions. Two bottom trawl surveys are conducted each year, one in the spring and one in the autumn. The survey is a standardized, stratified random design, with stratification based on bathymetry and multiple trawl sites within each stratum. Trawl sites are selected randomly, but the overall ship path is south to north. The survey covers the continental shelf and U.S. exclusive economic zone (EEZ) from Cape Hatteras, North Carolina into the Canadian EEZ. The primary gear is a bottom trawl, with CTD, multifrequency echosounder, and a host of other scientific sensor data collected ancillary to the bottom trawl catches.

EK500 Water Column Sonar Data Collected During DS0004

2000 Spring CalCOFI. The California Cooperative Oceanic Fisheries Investigations (CalCOFI) are a unique partnership of the California Department of Fish and Wildlife, NOAA Fisheries Service and Scripps Institution of Oceanography. The organization was formed in 1949 to study the ecological aspects of the sardine population collapse off California. Today our focus has shifted to the study of the marine environment off the coast of California, the management of its living resources, and monitoring the indicators of El Nino and climate change. CalCOFI conducts quarterly cruises off southern and central California, collecting a suite of hydrographic and biological data on station and underway.  Data collected at depths down to 500 m include: temperature, salinity, oxygen, phosphate, silicate, nitrate and nitrite, chlorophyll, transmissometer, PAR, C14 primary productivity, phytoplankton biodiversity, zooplankton biomass, and zooplankton biodiversity.

ME70 Water Column Sonar Data Collected During PC1007

Deepwater Horizon SEAMAP data. Unconventional configurations for both the EK60s and the ME70 allowed for three-dimensional images to be created from the split-aperture acoustic data. The ME70 configuration developed required Simrad to provide new software.

Using the EK60's, we imaged methane seeps in many locations surrounding the wellhead and at the wellhead. Seeps occur naturally in this area, and the challenge is to identify new or more intense seeps. Using both the EK60s and the ME70, we imaged the Deepwater Horizon rig on the seabed, among many riser pipes and other apparatus. When the Subsurface Monitoring Unit expressed concern that the noise level was too high for observations near the wellhead, I identified that the signal could be increased and the noise decreased, improving the signal-to-noise ratio by an order of magnitude, by increasing the pulse durations at 18 and 38 kHz from one to four milliseconds. Enabled by this enhanced configuration, I identified that the wellhead was burping methane hydrate intermittently and the emissions were rising at approximately 10 m per minute. The source of the bubbles and hydrate were observed on the BP-ROV images taken at the wellhead. When BP complained that the horizontal res
olution of our detections was too poor due to the 11 degree beamwidth of the 18 kHz transducer, I advocated the use of our new biplanar interferometric technique which increased the resolution one to two orders of magnitude (from ca. 300 m to ca. 10-20 m at 1500 m range) and provided sub-beam imagery (detailed in Cutter and Demer, 2010). Randy implemented his biplanar interferometric software (now BP-interferometry) and is generating very high-resolution 3-D images of the wellhead, seeps, and surrounding area. I generated 3-D maps of the seep locations and acoustically-tracked four large targets in the area, perhaps sperm whales.

EK60 Water Column Sonar Data Collected During DY0909

Acoustic-Trawl Survey of Walleye Pollock on the U.S. and Russian Bering Sea Shelf (DY0909, EK60). The Midwater Assessment and Conservation Engineering (MACE) program of NOAA National Marine Fisheries Service (NMFS), Alaska Fisheries Science Center (AFSC) conducted an acoustic-trawl (AT) stock assessment survey on the U.S. and Russian Bering Sea shelf during late spring/summer of 2009 to estimate the distribution and abundance of walleye pollock (Theragra chalcogramma). The survey was conducted from Bristol Bay, eastern Bering Sea in the U.S. to Cape Navarin, Russia, 9 June to 7 August aboard NOAA Ship Oscar Dyson, a 64 meter stern trawler equipped with acoustic and oceanographic instrumentation. The vessel departed Kodiak, Alaska on 5 June and arrived in Dutch Harbor on 7 August. The cruise was completed in three legs (leg 1, 9-28 June; leg 2, 1-18 July; leg 3, 21 July to 7 August), with port calls in Dutch Harbor, Alaska; a personnel exchange occurred in Dutch Harbor on 21 June. Fisheries gear research operations were conducted on 16 June and again 3-5 August. The EK60 echosounder system was calibrated at the start of the cruise in Three Saints Bay, Kodiak Island, Alaska 10-11 June, and at the end of the cruise in Anderson Bay, Unalaska Island, Alaska 6-7 August.

EK60 Water Column Sonar Data Collected During SE1006

Mesophotic coral environment monitoring and habitat surveys at the Main Hawaiian Island Chain (SE1006, EK60). The goals of the cruise were to collect a variety of data to assess the status of mesophotic corals in waters between the islands of Maui, Kahoolawe, Lanai, and Molokai.  Camera surveys of corals and fish were conducted by a live feed video camera attached to a Towed Optical Assessment Device (TOAD).  Three mooring, consisting of temperature and current meters, were recovered.  Three pairs of Tidbit temperature loggers were deployed.  CTD casts were conducted and light profiles taken at predetermined stations at midday.  Mixed-gas dive operations were conducted to assess coral communities and the presence of fish, aided with cameras.  Sand and gravel samples were taken for amphipod analysis.  Biological backscatter were recorded using an EK60 echosounder system operating at 38, 70, and 120 kHz along predetermined transects.
