Abstract: The Observer Program database consists of fish, invertebrate, and marine mammal
observations collected by fishery biologists while deployed on board commercial
fishing vessels or at shoreside processing plants participating in the Bering
Sea and Gulf of Alaska groundfish fisheries. This database covers observations
from 1993-2004. The specific data components collected are outlined in the
Groundfish Observer Manual. Once received by NOAA Fisheries, these data are
extensively checked for quality. Each record represents the summary of all the
observations made for a given taxa in a given year from each 20km by 20km grid
square; counts and weights are statistical estimates.
