| Title: | Effect of continental shelf canyons on phytoplankton biomass and community composition along the western Antarctic Peninsula / M.T. Kavanaugh, and 8 others. |

| Abstract: | Identifies four major canyons along latitudinal gradient west of Antarctic Peninsula, and compares biological-physical dynamics above and adjacent to canyons. Canyons showed higher sea surface temperature and reduced sea ice coverage relative to adjacent shelf areas, and pigment patterns indicated increased total phytoplankton and diatom biomass as well as increases in diatom relative abundance. Results indicate that canyons support phytoplankton community conducive to both grazing by krill and enhanced vertical export, although this cannot compensate for decreased biomass and diatom relative abundance during low sea ice conditions due to ingress of warm Upper Circumpolar Deep Water. Discusses results in relation to Adélie penguin habitat and population trends. |
