Short-lived radioisotope, sediment core photographs, and bulk density and porewater data from sediment cores collected aboard R/V Weatherbird II cruises WB-0813 and WB-1405 in the Gulf of Mexico from 2013-08-15 to 2013-09-27 (NCEI Accession 0229075)

This dataset contains short-lived radioisotope (SLRad), sediment core photographs, and bulk density/porewater data from sediment cores collected aboard R/V Weatherbird II cruises WB-0813 and WB-1405 in the Gulf of Mexico from 2013-08-15 to 2013-09-27. 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 “surficial unit” and 5mm sampling resolution intervals to the base of cores. SLRad 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.
