    "title": "Gas chromatography-mass spectrometry characterization, short-lived radioisotope, and other sediment data collected aboard R\/V Weatherbird cruise WB-0814 in the northern Gulf of Mexico from 2014-08-14 to 2014-08-28 (NCEI Accession 0226099)",
    "description": "This dataset contains data from sediment cores collected aboard R\/V Weatherbird cruise WB-0814 in the northern Gulf of Mexico from 2014-08-14 to 2014-08-28. It includes gas chromatography-mass spectrometry (GC-MS) characterization, bulk density\/porewater, short-lived radioisotope (SLRad), sediment core photographs, and Sediment texture and composition data. Marine sediment core samples were collected with multiple corers and were sectioned at specific intervals, and freeze-dried. Hydrocarbons were extracted from freeze-dried samples using a dichloromethane\/methanol (9:1) mixture of solvents and extracts were analyzed using an Agilent 7890B GC\/MS instrument attached to a 5977A mass detector. Bulk density\/porewater data reports measurements of sediment sample wet weight (g) and dry weight (g) for core sub-samples at 2mm sampling intervals for \u201csurficial unit\u201d and 5mm sampling resolution intervals to the base of cores. SLRad data and sediment texture and composition data were generated for selected core sub-samples. For sediment-core photograph data, sediment cores were longitudinally split and photographed with a Nikon D5100 digital camera with a scale in metric units (cm and mm) for a visual representation of sediment stratigraphy, color, and visual properties.",
