The Distribution of Zooplankton in the Bering Strait, July 1991.

Summary
Abstract: Zooplankton was sampled at 16 stations across the Bering Strait during a joint Russian-U.S. research cruise at R/V Tiglax in July 1991. Vertical stratified tows (0 - bottom and 0 – thermocline depth) were done with a ring net (1 m diameter, 333 µm mesh). Distinct zooplankton communities were found in the Bering Sea/Anadyr and Alaskan water masses. The influence of the Anadyr water led to a decline in the number of species in the Bering Shelf water community in the western Bering Strait. Zooplankton biomass in the surface layer of Alaska coastal waters was 1.5 times higher than biomass in the surface layer of Bering/Anadyr waters. No differences were observed in zooplankton density and biomass between the thermocline and surface and bottom and surface in Alaska coastal waters, while in other regions maximum density and biomass occurred below the thermocline. Total zooplankton abundance and biomass in the Bering-Anadyr water were dominated by North Pacific species (e.g., Neocalanus plumchrus, Neocalanus cristatus, Metridia pacifica), while in the Alaskan water Calanus marshallae, Acartia spp., Centropages abdominalis and larval euphausiids were common. Physical concentration of zooplankton by currents led to highest zooplankton densities near the Diomede Islands.

Purpose: To assess summer species composition, abundance and distribution of zooplankton across the Bering Strait.

Quality
ATTRIBUTE ACCURACY REPORT: The animals counts were done according to convention: sorting under a stereo microscope after preservations. Geographical positions were 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 and from the thermocline to the top. Abundance computed for each taxon 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: contact R/V Tiglax, U.S. F.W.S



LINEAGE/PROCESS STEP:
PROCESS DESCRIPTION: Zooplankton was collected with 333 µm mesh ring net on 16 stations in July 1991. Duplicate vertical tows were made at bottom - 0 m, and thermocline - 0 m depth increments. Zooplankton samples were gently rinsed from the net and preserved in buffered formaldehyde seawater solution (4% final concentration). Preserved samples were sorted and identified to the lowest taxon possible under stereo microscopes in the lab. Mean abundance and biomass resulted from repetitive tows were calculated for each layer on each station.


PROCESS DESCRIPTION: Added AOOS/IOOS core variables. Added ArcOD archive information

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.
