Sediment texture and composition data collected aboard R/V Weatherbird II cruise WB-0717 in the Gulf of Mexico from 2017-07-22 to 2017-07-28

This dataset contains sediment texture and composition data collected aboard R/V Weatherbird II cruise WB-0717 in the Gulf of Mexico from 2017-07-22 to 2017-07-28. Sediment texture and composition data were 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 were expressed as percent gravel, sand, silt, and clay. Percent of mud can be calculated by combining percent silt and clay. Sediment composition was expressed as percent total organic matter (TOM) measured by loss on ignition (LOI), percent carbonate content measured by acid leaching, and the percent insoluble residue (IR), which was likely dominated by terrigenous clastic (land-derived) sediment sources. The R/V Weatherbird II cruise WB-0717 was led by chief scientists Dr. Steve Murawski and Dr. David Hollander.
