Depth-integrated midwater pollock biomass in June and July 2008. Version 1.0

This dataset includes pollock biomass values summed between 16 m below the sea surface and 3 m above the seafloor within a rectangle with a north-south distance of 0.5 nmi (averaging distance along the survey transect) and an east-west distance of 20 nmi (interpolation distance 10 nmi to either side of the survey transect). The latitude, longitude, and vessel log distance values represent the starting location for each interval along the transect. The sum of biomass in all of these intervals will yield the sum total midwater pollock biomass measured by the survey.
