Sediment texture and composition data collected aboard the R/V Weatherbird II cruise WB-0717 in the northern Gulf of Mexico from 2017-07-19 to 2017-07-20

This dataset contains sediment Texture & Composition data collected from the northern Gulf of Mexico coast aboard the R/V Weatherbird II from 2017-07-19 to 2017-07-20. Sediment texture and composition data are generated for selected core sub-samples at 2mm sampling intervals for “surficial unit” and 5mm sampling resolution intervals to base of cores. Sediment texture values are expressed as % Gravel, % Sand, % Silt and % Clay as calculated by dry weight (g). % Mud can be calculated by combining % Silt and % Clay. Sediment composition is expressed as % TOM (Total Organic Matter) measured by Loss on Ignition (LOI), % Carbonate content measured by acid leaching, and the % Insoluble Residue (IR), which is likely dominated by terrigenous clastic (land-derived) sediment sources. The dataset contains the date, latitudes and longitudes of the sampling locations.
