Zooplankton counts from bongo net hauls in the Gulf of Alaska 2004

Transects sampled during the survey were perpendicular to shore and extended from nearshore across the continental shelf to oceanic waters beyond the 200-m shelf break. The survey was conducted aboard the contract fishing vessel F/V Great Pacific during 2004.

Zooplankton samples were collected using bongo nets with mesh sizes of 335 and 505 microns that were towed obliquely relative to the surface to a depth of 20 meters. The volume of water filtered by the net was estimated using flow meters. Plankton samples were transferred into vials, preserved in 5% formalin onboard the ship, and stored until a laboratory analysis was completed.
