Bulk density/porewater of sediments collected aboard R/V Point Sur cruise PS18-25 in the northern Gulf of Mexico from 2018-05-18 to 2018-05-23

This dataset contains bulk density/porewater of sediment cores collected aboard R/V Point Sur cruise PS18-25 in the northern Gulf of Mexico (NGOM) from 2018-05-18 to 2018-05-23. The dataset contains the sample collection date and location, water depth, site ID, core ID, 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 percent pore water. It reports 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 Point Sur cruise PS18-25, led by chief scientist Dr. Arne Diercks.
