Abstract:

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 base of cores. Bulk density is the dry weight per sampling volume expressed as g/cm^3 and is utilized in the calculation of Mass Accumulation Rates (MAR’s). Samples were collected in the northern Gulf of Mexico from November 2010 to September 2016.
