Abstract
This dataset reports measurements 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). Dataset also reports percent porewater. The sediment cores were collected onboard R/V Weatherbird II cruise WB-0915 and R/V Justo Sierra cruise JS-0815 in the southern Gulf of Mexico from 2015-07-30 to 2015-09-29. Chief scientists for these cruises were Dr. Steve Murawski and Dr. David Hollander.
Purpose
Determine dry bulk density and percent porewater content for sub-sampled core intervals.

Supplemental Information
Latitude and longitude of core site (decimal degrees), water depth of core site (m), core collection date (mm/dd/yyyy), site identification (ID), core identification (id), top depth of interval (mm), bottom depth of interval (mm), average depth of interval (mm), sediment wet weight (g), sediment dry weight (g), sample volume (cm3), bulk density (g/cm3), porewater (%), laboratory/facility analysis was performed at. Bulk density was calculated using sediment dry weight (g) and sample volume (cm3). Blank cell denotes analysis not performed for the interval, no data generated. The dataset includes cruise documentation.||Ocean Instrument MC-800 Multicore, Shipek Grab.|||
