Ecosystem monitoring information collected from Norseman II in Beaufort Sea for the ANIMIDA III project from 2014-07-31 to 2015-08-12 (NCEI Accession 0162530)

This dataset contains physical, chemical, and biological data collected during research cruises for the Arctic Nearshore Impact Monitoring in Development Area (ANIMIDA) III Study. The study occurred at 107 stations in the Beaufort Sea area in July and August of 2014 and 2015, and involved measurements and sampling of water, sediment, and biota conducted by investigators from several universities and research organizations. The study also includes a spring river survey conducted in May, 2015. The dataset includes more than 50,000 data values across 300+ variables, 500+ taxonomic names, 20+ collection methods, and 40+ lab analysis methods. Seawater samples include variables such as salinity, total suspended solids, and dissolved elements. Samples from the benthic zone include taxonomic counts and biomass. Sediment samples include variables such as hydrocarbons, metals, grain size distribution, and stable isotope ratios. All samples include numerical data value, date of sample collection, location in latitude and longitude coordinates, station identifier, sampling method, and the researcher responsible for the measurement. Furthermore, these data were harmonized according to a community driven set of controlled vocabularies for variable names, chemical speciations, units of measure, sample mediums, and sample types maintained by the Consortium of Universities for the Advancement of Hydrologic Science, Inc. The data are accompanied by an entity relationship diagram and data dictionary explaining the data structure. CTD, ADCP, and thermosalinograph sensor data are also provided following NCEI's netCDF templates for such data.
