Reports

sea ice biota aThe sea-ice related food web and biodiversity are critical components of the Arctic marine ecosystem. Higher trophic levels are directly or indirectly supported by over 2000 species of small algae and animals that are associated with sea ice, but are often inconspicuous to the naked eye.

These species inhabit a wide range of microhabitats inside the brine channel system, in melt ponds, leads, immediately underneath the ice, and including pressure ridges. The origin and age of sea ice influence the community composition of sea ice biota, with pronounced differences between annual landfast sea ice, offshore annual pack ice, and multiyear pack ice. Given the sea ice decline over at least the past few decades, shifts are expected in ice-associated biota.

The primary goals of the sea ice group in CBMP are to provide information on the biodiversity of sea ice biota and track their potential changes. We focus on four focal ecosystem components: Prokaryotic microbes; Ice algae and other protists; Sea-ice meiofauna; and Under-ice macrofauna. Given the lack of regular and systematic monitoring of sea ice biota, we rely on data compilations and meta-analysis.

PlanktonThe Plankton Expert Network is summarizing the spatial extent of past sampling, and producing maps showing movement of copepod  species from the Pacific into the Arctic.

Plankton are taxonomically and functionally diverse aquatic organisms that range in size from submicron (1 ¼m) to centimetres (cm). Phytoplankton are responsible for all primary production in the open ocean and are the base of the pelagic food chain supporting higher trophic levels.

Arctic phytoplankton and other protists, which include single-celled micro zooplankton, are the main food for copepods that are the principal food for larger macrozooplankton, and some species of fish and seabirds. Bacterioplankton are essential for degrading organic carbon in the ecosystem, and in the open ocean, including the Arctic, Bacteria and Archaea are responsible for remineralization of nutrients. Heterotrophic and mixotrophic microbial eukaryotes graze on Bacteria and Archaea as well as smaller phytoplankton. All of these single-celled plankton are subject to strong environmental selection.
