Bathymetry of Central Gulf of Alaska 

AFSC scientists with the RACE Groundfish Program proofed, corrected, and digitized 1.75 million lead-line and single-beam echosounder soundings from 225 National Ocean Service (NOS) hydrographic surveys represented as smooth sheets in the central Gulf of Alaska. This bathymetry compilation ranged geographically from the Trinity Islands in the west to Cape Ommaney in the east, covering an arc of about 1,400 km of shelf.

The geographic extent of this project matches the area of interest for the North Pacific Research Board's Gulf of Alaska Integrated Ecosystem Research Program (GOA-IERP), which is examining the physical and biological factors that influence the growth and survival of five species of juvenile groundfish in the Gulf of Alaska. Funding from the NMFS Alaska Regional Office's Essential Fish Habitat made some of this work possible.
