UAF - Arctic Ocean Chuckchi Sea August 1953-1954 Zooplankton vertical stratified collections on board of the Russian R/V Lomonosov, program ANII A-65Entry ID: ArcOD_2006P1
Abstract: Zooplankton collections were made to investigate interannual changes in species composition, abundance and distribution of the zooplankton in the Chuckchi Sea, one of the biologically lesser known areas of the Arctic. Vertical stratified tows (0-10 m, 10-25 m and 25 m bottom) were done with a Nansen net (0.5 m diameter, 333 µm mesh) at 21 stations in August of 1953 and August of 1954. The ship ... that was used is R/V/ Lomonosov; geo-referencing of stations was done. Temperature, salinity and oxygen concentrations were measured at each depth layer. Total zooplankton abundance and biomass in the southern Chuckchi Sea were dominated by North Pacific species (e.g. Metridia pacifica, Eucalanus bungii, Neocalanus plumchrus) and they were higher in 1954 then in 1953, indicating a substantial push of the Bering Sea water onto the Arctic shelf. Specifics of fieldwork in the Russian waters in the mid-1950 and translation issues between cyrillic and English spellings should be considered when analyzing these data.
Purpose: To assess late summer species composition, abundance and distribution of the zooplankton of the Chuckchi Sea for the years 1953-1954.

Quality ATTRIBUTE ACCURACY REPORT: The animals counts were done according to convention: sorting under a stereo microscope after preservations. Environmental data were taken with unknown accuracy, but best available method used. 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: 333 µm. Thickness of sampled layer: from the bottom to the top in three depth increments bottom-25 m, 25-10 m and 10 m surface.
Abundance computed for each taxa per sample as a number of specimens divided by volume of filtered water (estimated by multiplying the net mouth area by tow depth).
HORIZONTAL POSITIONAL ACCURACY REPORT: unknown accuracy, but best available method used

These data present a snapshot in time, but are representative for the location and depth where collected.
Identification is done where applicable and known; different taxonomies might result into different species names.
Pecularities of Russian name translations into English and for doing fieldwork in Russian waters in the mid-1950 should be considered when analyzing these data.
