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. Dataset also reports percent porewater. The sediment cores were collected onboard the R/V Weatherbird II cruise WB-0814 in the Gulf of Mexico from 2014-08-14 to 2014-08-28. Chief Scientists for this cruise were Dr. Steve Murawski and Dr. David Hollander, and the objective was to create Gulf-wide baselines for sediment and fish.
Purpose
Determine dry bulk density and % 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/yy), 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.|||
