Description:

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.

Taxonomic_Procedures:

Identification in lab with the aid of reference texts, keys and collections, and verified as required. Three separate labs processed the 85 µm bongo net, 1984 Wisconsin / neuston samples and the 1985 neuston / 500 µm Bongo net samples respectively. For details contact authors

Taxonomic_Completeness:

All specimens were captured in the plankton nets and were identified to the species level whenever possible with the following exceptions: for the 85 µm bongo net samples specimens were identified to the taxonomic group level for the Cumacean and Isopoda groups, and almost exclusively to the group level for the Rotifera, Polychaeta and Bivalvia groups. For the 763 µm Wisconsin, neuston and 500 µm bongo net samples processed by the second laboratory, specimens were identified to the taxonomic group level for the Foraminiferida and Ostracoda groups. Specimen identification data for the 1985 neuston and 500 µm bongo samples are reported with the most common species identified to genus or species, while the balance; the 1984 samples and the 1985 85µm bongo and Wisconsin net samples are identified to taxonomic group level. For the copepod group specimens caught in 85 µm net samples life history, stage or size range was fully described. All taxonomic classifications have been updated to meet classification standards represented in the International Taxonomy Information System (ITIS) database (www.itis.usda.gov ) as of May 2006.
