Trace metals and minor elements in sediment cores collected during the multiple R/V Weatherbird II cruises in the northern Gulf of Mexico following the Deepwater Horizon event from 2011-02-20 to 2017-07-28

This dataset reports trace metals and minor element composition of sediments obtained from the northern Gulf of Mexico following the Deepwater Horizon marine oil blow out event from 2011-02-20 to 2017-07-28. Sediment cores were collected aboard multiple R/V Weatherbird II cruises (WB1736, WB1701, WB1602, WB1502, WB1403, WB1304, WB1114) using an Ocean Instruments MC-800 multi-corer with special care not to disturb the sediment-water interface. Cores were carefully extruded using a calibrated threaded rod at 2 mm at the surface and 5 mm resolution below 2 cm. The dataset contains the date, locations (latitude and longitude), water depth of sample collection sites, and trace metal concentrations. It includes data from 2014 to 2017, and from 2011 to 2013 that are not included in the previous dataset that is available at GRIIDC under Unique Dataset Identifier (UDI) Y1.x031.000:0006 (DOI: 10.7266/N7C24TDB).
