Summary
Abstract: Zooplankton was collected from the Canadian Beaufort Sea shelf in July and September 1984, and July to September 1985. In the year 1984, 18 and 16 net samples were collected with a 763 µm Wisconsin and 500 µm neuston gear, respectively, from 18 stations. In the year 1985, 123, 54 and 229 net samples were collected with a 500 µm neuston, 85 µm bongo and 500 µm bongo gear, respectively, from 60 stations. Neuston gear sampled at the water surface while other gear sampled the water column. In the year 1984, 309068 plankton specimens were caught, with 64 taxonomic identifications from 15 taxonomic groups (phyla, classes, orders or suborders). In the year 1985 there were 210 taxonomic identifications, representative of 32 taxonomic groups, and a total catch of 22.38 million specimens. Copepods were predominant in all catches. Wet and dry biomass data of individual specimens for most plankton species are given for the samples of the year 1985. The maximum sample dry biomass for the 985 neuston and 500 µm bongo samples was 10.89 and 69.31 g/100 m3 of water filtered, respectively. Length-frequency data are given for 20 species, mostly copepods, captured in 23 (year 1985) 500 µm bongo net samples.

Purpose: To assess species composition, abundance, distribution and biomass of zooplankton across locations of the Canadian Beaufort Sea Shelf.

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

ERTICAL POSITIONAL ACCURACY REPORT: unknown accuracy, but best available method used



PROCESS DESCRIPTION: applicable since fully explained in Methodology: see above

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.
