We investigated the abundance of the meiobenthos and the biomass and community structure of the nematodes in the central Arctic Ocean along two separate transects during 1991 and 1994. Meiobenthos abundances ranged from < 100 to 600 individuals per 10 cm², in the same order of magnitude as in other oligotrophic areas of the world's deep ocean. Nematodes were the numerically dominant meiofaunal group at every station. Nematode biomass ranged from < 1 to 48 µg dry weight per 10 cm². A combination of water depth and latitude explained 55% of the variability among stations in nematode biomass and 67% of the variability of total abundance, implying that both vertical and advective fluxes are important sources of food to the meiofaunal communities.

The metazoan meiofauna in the region off Kapp Norvegia, Antarctica (Weddell Sea: 71°S, 12°W), was collected from depths between 211 and 2080m. Total meiofaunal abundance ranged from 815 to 5122 ind. per 10 cm² and total biomass from 126 to 966 µg dwt per 10 cm². Nematodes dominated the samples (range 83 to 97%) followed by harpacticoid copepods, polychaetes and kinorhynchs. A typical skewed length frequency distribution was obtained with most nematodes in the 0.4 to 0.6 mm size-class. The meiofauna communities were primarily influenced by bathymetric depth and food availability (e.g. organic matter and microbiota), which in turn are suggested to be directly related to phytoplankton blooms and associated sedimentation pulses. Standing stock and distribution... |
