The team completed two weeks of fieldwork in September 2001, collecting sediment profile images at 382 stations and sediment grab samples at 93 stations. This data set represents the sediment grain size and organic content information gathered from grab sampling. The Wells Reserve is using the 2001 grab and SPI information to characterize benthic habitats within the York and Webhannet rivers, and to examine relationships between animal communities and sediment characteristics as well as the potential effects of dredging activities. Grain size and percent organic content were measured from the sediment grab samples.

Vertical Positional Accuracy Report Not relevant to the data set. All grab data were not included in this data layer. Percent values of sand, silt, clay, gravel, sand and gravel combination, silt and clay combination, and total organic content, as well as a Folk description of grain size and median grain size (in phi units) are included. Other calculated grain size metrics (such as mean grain size and percent skewness) were not included, but these data can be found in the project database at the Wells Reserve. All data are believed to be logically consistent. Field Methods: Grabs for sediments and benthos were collected from 11 to 18 September at a total of 93 stations. A Young grab, 0.044 m2 surface area, was deployed twice to collect a sample for substrate and a sample for benthic community data. The Young grab is the same sampler used by EPA in its Environmental Monitoring and Assessment Program (EMAP) and Mid-Atlantic Integrated Assessment (MAIA) programs. The Young grab is similar to a van Veen grab that has been placed in a frame to hold it level with the sediment surface while a sample is collected. Grabs without frames tend to twist and collect uneven samples. Because of its frame, the Young grab functions well in both soft and hard sediment. Laboratory Methods: From the sediment grab, two sediment subsamples of about 50 g were taken, one for total organic carbon (TOC) analysis and one for sediment grain-size analysis. Both samples were placed on ice in the field and frozen in the laboratory until they were analyzed. TOC was determined by weight lost on ignition (Wells NERR, ME). Ten grams of wet sediment were dried at 60 degrees Celsius for 2 to 3 days and combusted at 500 degrees Celsius for 2 hours. Sediment grain-size distributions and sand fraction distributions were determined (by Virginia Institute of Marine Science (VIMS) Analytical Services Laboratory, Gloucester Pt., VA). Grain-size distributions were determined using wet sieve techniques for fines and sand size fractions were measured using a Rapid Sediment Analyzer. Reference: Folk, R.L. 1974.
