Abstract:

This dataset 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. Dataset also reports percent porewater. The sediment cores were collected onboard the R/V Weatherbird II cruises WB-0815 and WB-0915 in the Gulf of Mexico from 2015-08-16 to 2015-10-01. Chief Scientist for these cruises was Dr. Steve Murawski 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.

Data Parameters and Units:

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.

Instruments:

Ocean Instrument MC-800 Multicore, Shipek Grab.
