This dataset contains sediment texture & composition data collected aboard R/V Weatherbird II cruise WB-0517 in the Gulf of Mexico from 2017-05-11 to 2017-05-23. Twelve sites were sampled using a multi-corer between 316 and 1670 m depth around northwest Cuba. 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 the 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 cruise documentation was provided for the R/V Weatherbird II cruise WB-0517, led by chief scientists Dr. David Hollander and Dr. Steve Murawski.
