Arctic Ocean: Amundsen and Nansen basins – July-August 2001. Vertical and stratified zooplankton sampling onboard the Swedish icebreaker Oden, program FAMIZEntry ID: ArcOD_2006P8
Abstract: Studies of distribution and abundance of zooplankton were performed in a) Amundsen basin (89-88oN drift) and b) Nansen basin (four stations in the MIZ and two stations in the open water). In Amundsen basin, stratified (200-100m, 100-50m, 50-0m) and graduated (200-0m, 100-0m, 50-0m) tows were done with a WP-2 net (0.5 m2 mouth area, 180 µm mesh) in August 2001. In Nansen basin, 100-0m vertical tows were done with a WP-2 net (0.5 m2 mouth area, 180 µm mesh) in July 2001 The ship was Swedish icebreaker Oden. Geo-referencing of stations was done with a GPS in latitude/longitude using 4 decimals. In both basins Calanus glacialis and C. hyperboreus dominated zooplankton biomass.
Purpose: To study composition and distribution of zooplankton in the Arctic Ocean.

Quality ATTRIBUTE ACCURACY REPORT: The animals counts were done according to convention or SIO, RAS; (contact authors for exact details): sorting under a stereo microscope after preservations. Geographical positions taken from ship log before deploying the net.
LOGICAL CONSISTENCY REPORT: The same procedures were used at all sites and for all species; findings should ... be consistent.
COMPLETENESS REPORT: Mesh size used: 180 µm. Sampled layers in Amundsen basin: 200-100m, 100-50m, 50-0m (St. 5/1-5/2) and 200-0m, 100-0m, 50-0m (St. 5/3, 5/4, 5/5). In Nansen basin: 100-0m. Abundance computed for each taxon per cubic meter as a number of specimens in sample divided by volume of filtered water (estimated by multiplying the net mouth area by tow extension).
HORIZONTAL POSITIONAL ACCURACY REPORT: GPS method applied, 4 decimals in latitude and longitude
