This dataset contains Bulk Density/Porewater of sediment cores 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. The dataset contains the location, date, water depth, core ID, and top depth of interval (mm), bottom depth of interval (mm), average depth of interval (mm), wet weight (g), dry weight (g), sample volume (cm3), bulk density (g/cm3), and % pore water. Measurement 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. Bulk density is the dry weight per sampling volume expressed as g/cm3 and is utilized in the calculation of Mass Accumulation Rates (MAR’s). 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.
