Sub-Collection of The Global Plankton Database with data of the data collected during the Western Beaufort Sea Ecological Cruises (WEBSEC). more

Midwater invertebrates were collected in the southeastern Chukchi Sea. A 1.8m Isaacs-Kidd midwater trawl was used at 20 stations to collect 81 semi-quantitative samples; a 3m otter trawl was used at one station to collect two qualitative samples. Data tables list the species collected and their numbers, size range, and displacement volumes for the midwater trawl stations and a species list only for the otter trawl station. One hundred three species of invertebrates were identified from the midwater trawl samples, and 33 species were identified from the otter trawl samples. Amphipods were the most diverse group (40 species) and decapod shrimps the next most diverse (14 species). Numbers of species in a sample varied from 4 to 40 (mean 17). After removal of jellyfishes, the most important contributors in numbers and volume to the catches were euphausiids and mysids. Purpose: The Western Beaufort Sea Ecological Cruises (WEBSEC) were a sequence of oceanographic cruises sponsored by the U.S. Coast Guard to assess the Alaskan arctic marine environment and biota before major industrial development. The Coast Guard enlisted the efforts of federal, state, and university research groups for the program, and the National Marine Fisheries Service contributed to the first three cruises with studies of zooplankton, midwater invertebrate, and fishes. SUPPLEMENTAL INFORMATION: COPEPOD is a new effort by NOAA - National Marine Fisheries Service (NMFS) to provide investigators with an integrated data set of quality-controlled, globally distributed plankton abundance, biomass and composition data, along with co-sampled environmental data. NMFS-COPEPOD is designed to help the investigator easily see exactly what data are currently available and then download it in a usable format. In addition to data distribution maps, NMFS-COPEPOD offers a variety of content summaries and searching options. Data was published in May 2010 on the OBIS-USA web site. Refer to NOAA Technical Report NMFS SSRF-710 published in April 1977 for further information relating to the study. Contact COPEPOD for a copy of the publication. Record Count 830, Taxa Count 58
