Abstract:

This dataset reports grain size for five sediment samples collected using multicores during the R/V Weatherbird II cruise in the Northern Gulf of Mexico from August 5th to 9th, 2012. Grain sizes are reported as percent of the sample for 47 size classes. The percent mud content for each sample is calculated and samples are classified as mud or sandy mud. Results are reported in triplicate for each sample and the average for each sample is included. Samples were analyzed in the laboratory by laser diffraction.

Purpose:

To evaluate the biological diversity and trophic interactions among organisms ranging from primary producers to apex predators and from the deep-sea benthos to the coast. These data contribute to a food web model used to determine risks to ecosystem structure and function and regional economies following from extreme anthropogenic events (e.g., discharged and background hydrocarbon) and adaptive management strategies.

Data Parameters and Units:

Sample name, measurement date and time, analysis date and time, particle refractive index, dispersant name, dispersant refractive index, uniformity: uniformity of grain sizes in sample, specific surface area, d(0.1), d(0.5), d(0.9), result between user sizes (mm), result between user sizes (um), Percent Mud (clay and silt)
