Description

The files contain data on zooplankton sampled in October 2020 in the northern Bering Sea and Chukchi Sea using a vertical ring net. Data provided are abundance and biomass. 

Data Records

The data in this sampling event resource has been published as a Darwin Core Archive (DwC-A), which is a standardized format for sharing biodiversity data as a set of one or more data tables. The core data table contains 19 records.

2 extension data tables also exist. An extension record supplies extra information about a core record. The number of records in each extension data table is illustrated below.

Project Data

The Arctic Marine Biodiversity Observing Network (AMBON) project is a sustainable approach to biodiversity observing in the Chukchi Sea and serves as one component in the National Marine Biodiversity Observing Network (MBON) program. Grounded in the concept that sustained biodiversity across ecosystem components is critical for maintaining healthy ecosystem functions, this project is using strategic collaborations to build an observing network in the Arctic Chukchi Sea.

Title A sustainable, integrated AMBON in the Chukchi Sea
Funding The AMBON project (NA19NOS0120198) was funded through the National Ocean Partnership Program (NOPP) with financial contributions to AMBON by the Bureau of Ocean Energy Management (BOWM), the National Oceanic and Atmospheric Administration (NOAA), The National Aeronautics and Space Administration (NASA), and the Office of Naval Research (ONR).
Study Area Description The Chukchi Sea is a shallow Arctic inflow shelf that is strongly connected and influenced by processes and waters in the Bering Sea. Because of sea surface height differences, water typically flows northward from the Bering Sea, through the Bering Strait, carrying significant amounts of heat, freshwater, and nutrients into the Chukchi Sea.
Design Description Samples within the AMBON project are collected along standard transects that cross the shelf from shallow coastal regions to the deeper offshore regions and crossing different water masses. Transects range from the northern Bering Sea to the northern Chukchi Sea.

Sampling Methods

Samples were taken with a 60-cm diameter ring net, affixed with a 150 um mesh and a flowmeter. Nets were taken in vertical hauls, from approximately 3-5 m above the bottom to the surface. Volume filtered was calculated.

Study Extent Sampling occurred at multiple stations along the cross-shelf transects from the northern Bering Sea to the Chukchi Sea.
Quality Control Zooplankton organisms from net hauls were identified by taxonomic experts using microscopy

Method step description:

  1. Rinse haul, preserve in ethanol, identify and count a known well-mixed subsample of the haul. Calculate biomass of species based on organism size and conversion coefficients. Number and weight are standardized to the water volume filtered through the net
