Sediment texture and composition data collected aboard R/V Weatherbird II cruises WB-0911, WB-1125 and WB-1114 in the northern Gulf of Mexico from 2011-02-20 to 2011-09-26

This dataset contains sediment texture and composition data collected aboard R/V Weatherbird II cruises WB-0911, WB-1125 and WB-1114 in the northern Gulf of Mexico from 2011-02-20 to 2011-09-26. 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. Cruise documentation was provided for each of the R/V Weatherbird II cruises. The cruises were led by Brian Donahue (WB-1114), Rebekka Larson (WB-0911), and Charles Kovach and Sue Murasko (WB-1125).
