        abstract:  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).
        purpose:  This project aimed to characterize Chukchi Sea surface sediments using Van Veen grabs. Sediment grain size and the organic content within sediments are important metrics for benthic organisms in terms of their habitat and food web requirements.

                description:  Parameter or Variable: SEDIMENT - GRAIN SIZE (measured); Units: percent; Observation Category: in situ; Sampling Instrument: sediment sampler - grab; Sampling and Analyzing Method: A Van Veen grab (0.1 m2 sediment grab), weighted with 32 kg of lead was used in the collection of surface sediment samples. Sediment was collected from the first van Veen grab used for collection of sediment samples. Sediment grain size was determined in the laboratory after removal of organics and of iron oxides following the process of Gee and Bauder (1986), and following the methods outlined in Grebmeier et al. (1989, 2015). Sediment were sorted into Phi classes with percentages reported in the data tables in this dataset..
