EK60 Water Column Sonar Data Collected During MF1002

2010 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.

EK60 Water Column Sonar Data Collected During NF-13-02-USVI

NF-13-02-USVI Mapping Essential Fish Habitat in the US Caribbean to Inform MPA Management (EK60). Scientists will collect high resolution multibeam and acoustic fisheries data in mid-water 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 moderate-depth Remotely Operated Vehicle (ROV) and drop camera. The vehicle has video and frame camera capability to depths of 300 meters and will be used for point sampling within areas mapped during this mission.

EK60 Water Column Sonar Data Collected During SE0803

Oceanographic Survey of Cross Seamount and Control Sites (SE0803, EK60). The goals of the cruise were to collect acoustic backscatter and oceanographic data at Cross Seamount (18Â°43.285â N, longitude 158Â° 15.710â W) and at control sites in the surrounding environment.  Data collected consisted of CTD casts, trawl samples, and continuous monitoring of currents and biological acoustic backscatter.  CTD cats were conducted at predetermined stations.  CTDs were equipped with oxygen sensors and fluorometers.  Trawl operations were conducted at predetermined stations using a Cobb trawl at depths of the shallow (nighttime) and deep (day and nighttime) sound scattering layers.  Currents were continuously monitored using an RD Instruments Acoustic Doppler Current Profiler (ADCP) operating at 75 kHz frequency.  Biological backscatter were recorded along predetermined transects using the EK60 echosounder system at 38, 70, and 120 kHz frequencies.

EK60 Water Column Sonar Data Collected During SE1306_BeforeCalib

Comparison of fishery-independent methods for sampling Main Hawaiian Islands Bottomfish assemblages (SE1306_BeforeCalib, EK60). Optical, active acoustics, and research fishing data on bottomfish abundance and biomass were collected over predetermined grids to compare results of methodologies.  Optical data were collected using a baited and unbaited stationary Botcam, a SeaBED AUV, and a Phantom ROV.  Acoustics data were collected using a narrow-beam EK60 system operating at 38, 70, 120, and 200 kHz frequencies.  Research fishing was conducted using hook-and-line on small boats.  Simultaneous AUV and ROV with active acoustics were operated to obtain target strength measurements of fish with known species and sizes.  Bottomfishing off the Sette were conducted simultaneously with acoustics data collection to further groundtruth the acoustics data.

Acoustic-Trawl Surveys of Walleye Pollock (Gadus chalcogrammus) in the Gulf of Alaska (SH2019-04). The Midwater Assessment and Conservation Engineering (MACE) program of NOAA Fisheries, Alaska Fisheries Science Center (AFSC) conducted acoustic-trawl (AT) stock assessment surveys in the Shelikof Strait, Chirikof shelf break,and Marmot Bay areas of the Gulf of Alaska (GOA) in the late winter/early spring of 2019 to estimate the distribution and abundance of walleye pollock (Gadus chalcogrammus). This survey was conducted aboard NOAA Ship Bell M. Shimada, a 64 meter stern trawler equipped with acoustic and oceanographic instrumentation. The primary acoustic instrument for the survey was a Simrad EK60 split-beam echosounder system utilizing five frequencies (18, 38, 70, 120, and 200 kHz). The vessel departed Kodiak, Alaska on 6 March and conducted an acoustic system calibration in Kalsin Bay, Kodiak Island 7 March. The Shelikof Strait was conducted 7-16 March, the Chirikof shelf break sure was conducted 16-18 March, and the Marmot Bay survey was conducted 19-20 March. A post-cruise acoustic system calibration was conducted 20-21 March in Kalsin Bay and the vessel arrived in Kodiak, Alaska on 21 March.

EK60 Water Column Sonar Data Collected During FR1003

2010 California Current Ecosystem Survey. Measurements of volume backscattering strength (Sv; dB re 1 m) and target strength (TS; dB 1 m2) were made using four calibrated Simrad EK60 general purpose transceivers (GPTs) configured with split-beam transducers at frequencies of 38, 70, 120, and 200 kHz. To index the data by time and geographic position, a GPS receiver provided navigational data to the echosounder software (ER60). The echosounder system was tested and calibrated while FROSTI was anchored at Elliot Bay Anchorage (Washington) two days prior to the start of the cruise. EK60 data was collected to 250 m depths by transmitting 1024-Âµs pulses of the four frequencies simultaneously, every 0.5 seconds. The depth range was chosen to accommodate the depth distribution of CPS (i.e., ca. 70 m depth) and krill (i.e., ca. 250 m depth), and the fast pulse repetition allows multiple insonification of relatively small fish schools  at the sampling speed of 8 kts.

The echoes were received with bandwidths of 2.425, 2.859, 3.026, and 3.088 kHz, respectively, and digitized every 256 Âµs (ER60; .raw data format) in a laptop computer. All the EK60 frequencies were triggered simultaneously, and all other echosounders, speed logs, and sonars operating at or near the survey frequencies were secured during survey operations. Exceptions were made during directed trawl operations when a net sounder was activated.
