Abstract
This dataset report 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). The dataset also reports percent porewater. The sediment cores were collected onboard R/V Weatherbird II cruises WB-0717 and WB-1217 in the Gulf of Mexico from 2017-07-19 to 2017-12-05. Chief scientists for these cruises were Dr. Steve Murawski, Dr. David Hollander, and Dr. Patrick Schwing, and the objective was to create Gulf-wide baselines for sediment and fish.
Purpose
Create Gulf-wide baselines for sediment and fish.

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.|||
