This data set represents the sediment grain size gathered from grab sampling in 2003 (24 stations).In Fall/Winter 2002, researchers from the Virginia Institute of Marine Science (VIMS) and the NOAA Office for Coastal Management conducted a project to map benthic habitats by Catlett and Goodwin Islands on the York River, Chesapeake Bay, Virginia. Sediment grab samples were collected at 56 stations and sediment profile images were collected at 200 stations. Sampling areas were also surveyed using side scan sonar and multibeam bathymetry sensors. Scientists from the Virginia Institute of Marine Sciences returned to sample a subset of the 2002 sediment grab data in 2003 and then again in 2004. A subset of SPI stations (79) were revisited in 2004. Original contact information: Contact Org: NOAA Office for Coastal Management Phone: 843-740-1202 Email: coastal.info@noaa.gov

Sediment grab samples were collected using a Shipek grab at pre-determined locations in the harbor. 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 Geographic Information System (GIS) to characterize sediment environment in New York/New Jersey Harbor.

The Apalachicola Bay National Estuarine Research Reserve and the NOAA Office for Coastal Management worked together to map benthic habitats within Apalachicola Bay, Florida. The bay and the lower portions of four distributaries were surveyed on 11-22 October 1999 using three benthic sampling techniques. This data set represents the sediment grain size and organic content information gathered from grab sampling. Grabs were collected at 136 stations throughout the bay.

In fall 2001, researchers from the Wells National Estuarine Research Reserve, Virginia Institute of Marine Science, and the NOAA Office for Coastal Management conducted a project to map benthic habitats in the York and Webhannet rivers in southern Maine. 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.
