This dataset contains fish haul and specimen information collected during the Arctic Marine Biodiversity Observing Network (AMBON) research cruise in 2017. During the cruise, demersal fishes were collected with a plump-staff beam trawl, identified to species, and their length was measured while onboard. A subset of specimens was frozen or preserved in ethanol for laboratory analyses to contribute to this and other datasets. Juvenile and pelagic fishes were also captured with an Isaac-Kidds midwater trawl. The final dataset consists of 3 comma separated values files (csv), one lookup table as a comma separated values file (csv), and two ISO 19110/19115 metadata records in xml form. The data files are presented in a table structure using Darwin Core OBIS-GBIF form (https://obis.org/manual/dataformat/#emof), using Darwin Core term names as column names and in keeping with that metadata standard (https://dwc.tdwg.org/). They are: AMBON2017_fish_Event_DWC.csv, AMBON2017_fish_MoF_DWC.csv, AMBON2017_fish_Occurrence_DWC.csv. This dataset also contains the file AMBON2017_Fish_data_HaulInfo_lookupTable.csv, describing details of sampling efforts such as stations and date and comments/notes of sampling efforts.

This dataset contains marine mammal observation data conducted during shipboard transects in the Chukchi Sea during the 9 August - 3 September 2015 Arctic Marine Biodiversity Observing Network (AMBON) research cruise.

Two data files contain the dates, times, latitude, longitude, species and best-high-low estimates of numbers for each cetacean (whales) and pinniped (seals, seal lions, and walrus) sightings. A third data file contains the track of the ship (as geographic coordinates) and the Beaufort sea state at two minute intervals as a measurement of effort. This dataset was transformed from the native format into a table structure using Darwin Core Archive (DwC-A, occurrence core) term names as column names.

This dataset contains seabird survey and associated environmental conditions data collected in the Chukchi Sea during the 9 August - 3 September 2015 Arctic Marine Biodiversity Observing Network (AMBON) research cruise. Seabirds were surveyed using line transect methods. Seabird observations were recorded directly into a laptop computer using software which logged the geographic coordinates of each sighting. Incidental sightings of marine mammal were also recorded. Supplementary environmental data are included for the beginning of each survey period. The dataset is two comma-separated values (csv) files. The file named dlog_2015_dwc_core.csv contains the count of observed marine birds and mammals by species, their behavior, and the environmental conditions recorded during the surveys for the 2015 research cruise. The file named taxon_codes_2015.csv is an associated taxon code list of the observed species. This dataset was transformed from the native format into a table structure using Darwin Core term names as column names.

This dataset contains zooplankton species biomass and abundance data collected in the Chukchi Sea during the 11 August through 3 September, 2015. Arctic Marine Biodiversity Observing Network (AMBON) research cruise on the vessel Norseman II. This dataset contains three comma separate values (csv) files. The data were collected from zooplankton samples caught with traditional 150µm plankton nets and taxonomically identified. Each data file include the location, date, time, depth, and identification of zooplankton taxa collected during the 2015 AMBON cruise. The data in the file named AMBON2015_Zooplankton_Abundance_150_DC.csv and AMBON2015_505_Zooplankton_Abundance_DWC.csv consists of abundance per taxon of zooplankton. The data in the file named AMBON2015_Zooplankton_Biomass_150_DC.csv and AMBON2015_505_Zooplankton_Biomass_DWC.csv consists of biomass per taxon of zooplankton.

This dataset contains summary measurements of surface sediment collected at fixed stations in the Chukchi Sea during the 12 August - 3 September 2015 and 6 August - 22 August 2017 Arctic Marine Biodiversity Observing Network (AMBON) research cruises. A Van Veen grab was used for collection of sediment samples at AMBON sampling stations. Sediment grain size was then determined in the laboratory after removal of organics and iron oxides. This dataset contains two comma-separated values (csv) files containing summary measurements of surface sediment collected at each station for AMB15 and AMB17 by Station Number, Station name, Date (YYYYMMDD), latitude (dec deg N), longitude (dec deg E), and Station Depth (m). The following parameters are listed in this data file for surface sediment values: grain size percentage (≤0 phi, 1 phi, 2 phi, 3 phi, 4 phi, sand 1-4 phi, ≥5 phi, and modal phi size), percent total organic carbon (TOC), percent total organic nitrogen (TON), C/N ratio, del-13 carbon (per mil), del-15 nitrogen (per mil), surface sediment chlorophyll (chl a; mg/m2), and stable isotope values of 13C and 15N (per mil vs VPDB and air, respectively).

The Alaska Fisheries Science Center's Status of Stocks and Multispecies Assessment (SSMA) Programs Fishery Interaction Team (FIT) conducted a fish survey in the marine offshore waters of the Beaufort Sea during the month of August, 2008. The Mineral Management Service (MMS) provided funding for the survey. The results of the survey provided estimates of abundance, species composition and biological information of marine fish and invertebrates, oceanographic properties and information on the macro- and micro- zooplankton communities.
