Full Citation Examples
Calibrated midwater and bottom backscatter data collected continuously with ES-60 echosounders throughout the bottom trawlsurvey period, continuing a time series of such data begun in 2005. Raw acoustic data was logged continuously 24 hours/day for each of the four legs of the cruise. The data is stored as raw files on the AFSC network drive.

| Abstract: |
Calibrated midwater and bottom backscatter data collected continuously with ES-60 echosounders throughout the bottom trawlsurvey period, continuing a time series of such data begun in 2005. Raw acoustic data was logged continuously 24 hours/day for each of the four legs of the cruise. The data is stored as raw files on the AFSC network drive. |
| Purpose: |
Acoustic data collection in conjunction with bottom trawling operations allows us to address several difficulties in obtaining representative trawl samples such as: searches for trawlable location over untrawlable ground, seafloor characterization at abandoned stations, mapping seafloor areas without adequate NOS charting, and quantifying schools of off-bottom fish. |
