5 Arctic Ocean Food Webs Short growing season Intense ice algal and phytoplankton blooms High zooplankton biomass (esp. copepods) High benthic biomass (shallow shelves) Unique assemblage of marine mammals
6 Arctic Ocean Food Webs Two copepod spp. represent majority of zooplankton biomass. Calanus hyperboreus (slopes and basins) Calanus glacialis (shelves) Primary prey spp. for bowhead whales
7 Bowhead whales (Balaena mysticetus): migration, ice navigation
