Field Activity G197BS

Identifier G197BS
Alternate names G-1-97-BS
Purpose Identify and document seafloor disruption due to trawling for fish.
Description Chief Scientists: Mike Marlow, Robert McConnaughey. Geophysical and Sampling and Video data (sidescansonar, 3dot5khz, GPS, underwatertelevision, boxcore, VanVeengrab, integratednavigation) of field activity G-1-97-BS in Bristol Bay, Bering Sea, Alaska from 07/31/1997 to 08/14/1997
Location Alaska
Summary Sidescan-sonar data collected in 3 areas (EXP1, BB, and COD), and video collected in 2 areas (EXP1 and BB). Robert McConnaughey directed the collection of numerous sediment samples for examination by National Marine Fisheries Service biologists.
Info derived Maps of surface morphology derived from sidescan mosaics.
Comments This was a cooperative cruise with NMFS. The USGS has the sidescan data and video, NMFS has the sediment samples.
