My name is Dave Kimmel and I am a research oceanographer with the Eco-FOCI program of the Alaska Fisheries Science Center. I specialize in zooplankton ecology and the goal of our research is to characterize the distribution and abundance of the mid-sized zooplankton community. We do this by towing a bongo net with two different mesh sizes. We then preserve the sample from one side of the net and do a rough count of zooplankton on the other side of the net. The map shows the abundance of zooplankton > 2 mm in the bongo nets, as estimate from the rough count. These larger zooplankton, in this case dominated by Calanus glacialis/marshallae, were present in very low numbers in the northern and western portion of the Chukchi Sea grid. This area was characterized by high crab zoea/megalopae counts and the presence of phytoplankton. As we approached the Chukchi slope, we encountered increasing numbers of Calanus and these abundances were coincident with a colder water mass and phytoplankton presence in the nets decreased. We also observed several individual Calanus hyperboreus, a larger, Arctic copepod, in the net samples. This suggests that colder water from the Arctic basin is being transported into the eastern portion of the Chukchi Sea.
