Benthic epifauna biomass and abundance data, Arctic Marine Biodiversity Observing Network (AMBON) research cruise, August 2017 (NCEI Accession 0213519)

Preview graphic

Marine biodiversity is a key component of ocean health. Monitoring and understanding marine biodiversity is essential for our ability to forecast and respond to changes. The goal of the Arctic Marine Biodiversity Observing Network (AMBON) project is to demonstrate and build an operational marine biodiversity observing network from microbes to whales, integrating diversity levels from genetic to organismal. AMBON field region is located on the Chukchi Sea continental shelf in the US Arctic as a region exposed to climatic changes and anthropogenic influences.

This dataset contains biomass and abundance data collected in the Chukchi Sea during the August 2017 Arctic Marine Biodiversity Observing Network (AMBON) research cruise. Epifauna samples were collected using beam trawl during a research cruise during August 2017 in the Chukchi Sea, U.S. Arctic. The data consist of biomass per taxon of epibenthic invertebrates. The dataset is a comma separated values file exported from a Microsoft Excel spreadsheet.

This dataset was transformed from the native format into a table structure using Darwin Core term names as column names.

Purpose	The purpose of this dataset is to describe the epibenthic community in the study area in the Chukchi Sea, especially their species composition, abundance, and biomass.
Use Limitations	accessLevel: Public Distribution liability: NOAA and NCEI make no warranty, expressed or implied, regarding these data, nor does the fact of distribution constitute such a warranty. NOAA and NCEI cannot assume liability for any damages caused by any errors or omissions in these data. If appropriate, NCEI can only certify that the data it distributes are an authentic copy of the records that were accepted for inclusion in the NCEI archives. Users of AMBON data are encouraged to cross-reference the AMBON master station list file if attempting to spatially align or synthesize data across AMBON study disciplines. The station masterlist contains information about the station identifiers, locations, and bottom depth during the 2017 research cruise. At each station more than one observation or sample type may have occurred by different AMBON researchers during which alternate station names may have been applied.

Processing Steps	Parameter or Variable: organismQuantity (calculated); Units: gram wet weight per 1000 m2; Observation Category: in situ; Sampling Instrument: trawl; Sampling and Analyzing Method: Epibenthic invertebrates and demersal fishes were collected with a plumb-staff beam trawl with a 2.26 m opening, with a 7 mm mesh net and a 4 mm cod end liner. Trawls were conducted during the night for 2-5 min duration at ~1.5 knots. Trawl hauls were rinsed, if necessary, and then sorted on board to the lowest taxonomic level possible. Abundance and biomass for all taxa were then quantified for each haul as catch per unit effort (CPUE) based on trawled distance and width of net opening and trawling speed.; Data Quality Method: NA. Parameter or Variable: taxonID (calculated); Units: integer; Observation Category: laboratory analysis; Sampling Instrument: trawl; Sampling and Analyzing Method: Epibenthic invertebrates and demersal fishes were collected with a plumb-staff beam trawl with a 2.26 m opening, with a 7 mm mesh net and a 4 mm cod end liner. Trawls were conducted during the night for 2-5 min duration at ~1.5 knots. Trawl hauls were rinsed, if necessary, and then sorted on board to the lowest taxonomic level possible. For invertebrate taxa that could not be identified on board, voucher specimens were preserved in 4% formaldehyde or 99% molecular-grade ethanol for later consultation with taxonomic experts. All invertebrates, except for colonial taxa, were enumerated; bulk wet weight was determined at the lowest taxonomic level using spring and digital hanging scales. Trawl distance was assessed by depth recordings by a time-depth recorder (TDR, Star Oddi) attached to the net opening multiplied by trawling speed. Abundance and biomass for all taxa were then quantified for each haul as catch per unit effort (CPUE) based on trawled distance and width of net opening and trawling speed.; Data Quality Method: Validity of taxonomic names was checked against the World Register of Marine Species (WoRMS, www.marinespecies.org/) Unknown organism identification was checked by taxonomic experts. In cases where no firm identification could be obtained, the lowest known taxonomic level is listed (e.g., class or phylum)..
