Abstract:
"A Shipek grab (0.04 m2) was used to collect benthic and sediment samples from one-third of the stations and the grab was operated concurrently with deployment of a sediment profile camera from a different area of the RV Onrust. Two grabs were taken at each of the grab-sampled stations. All sediments collected in the second grab were subsampled and frozen for grain size and total organic content (TOC) analyses. Texture analyses were performed by Tierra Consulting, Inc., Mobile, AL. Each sample was washed with de-ionized water, dried, and weighed. The coarse fraction was separated from the fine fraction (sand/silt) by sieving through U. S. Standard Sieve Mesh No. 230 (62.5 mm). Sediment texture of the coarse fractions was determined at half- phi intervals by passing the sediment through nested sieves on a Ro-Tap apparatus. The weight of the material on each sieve was recorded. A Sedigraph 5000 ET Particle Size Analyzer was used to analyze the fine fraction (<62.5 mm). Sediment texture descriptions followed the Wentworth classification. Total organic carbon (TOC) analyses were done at the USACE Waterways Experiment Station Vicksburg MS; using a weight-loss-upon-ignition procedure. Samples collected in the field were stored in a freezer until analysis could be performed. After thoroughly mixing the thawed contents of the bag, two 10-g samples of sediment were removed, dried, weighed, ignited at 500 degrees Celsius to drive off organic material and re-weighed. TOC was assumed to be the weight lost upon ignition and expressed as a percentage."
Purpose:
"Grain size distributions and organic content were measured and used to assess sediment conditions in New York/New Jersey Harbor and to compare with sediment profile images taken at the same stations. All data were entered into a database and the database was then used in a GIS to characterize sediment environment in New York/New Jersey Harbor."

Attribute_Accuracy_Report:
Values were checked against hard copy data sheets provided by the analysis laboratory. Total organic carbon analyses were repeated for samples where two subsamples differed by more than 10% (e.g., if sediment TOC was 1% the replicate subsample must have a TOC between 0.9% and 1.1%).
