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. The dataset also reports percent porewater. The sediment cores were collected on board the R/V Weatherbird II cruise WB-0812 in the northern Gulf of Mexico from 2012-08-14 to 2012-08-16. Chief scientists for this cruise were Dr. Steve Murawski and Dr. David Hollander.

Purpose:

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/cm3.

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.
