In Fall/Winter 2002, researchers from the Virginia Institute of Marine Science (VIMS) and the NOAA Coastal Services Center 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. VIMS and the NOAA Coastal Services Center are using the acoustic, grab, and SPI information (collected in 2002, 2003, and 2004) to characterize benthic habitats by Catlett and Goodwin Islands on the York River, and to examine relationships between animal communities and sediment characteristics. Grain size was measured from the sediment grab samples. completed NOAA Coastal Services Center CRS Program Manager (843) 740-1200 (843) 740-1224 2234 South Hobson Avenue Charleston South Carolina 29405 U.S.A. pointOfContact notPlanned Oceans > Marine Sediments > Biogenic Sediments Oceans > Marine Sediments > Bioturbation Oceans > Marine Sediments > Geotechnical Properties Oceans > Marine Sediments > Sediment Chemistry Oceans > Marine Sediments > Sediment Composition Oceans > Marine Sediments > Sediment Transport Oceans > Marine Sediments > Sedimentary Structures Oceans > Marine Sediments > Sedimentary Textures Oceans > Marine Sediments > Sedimentation Oceans > Marine Sediments > Stratigraphic Sequence Oceans > Marine Sediments > Terrigenous Sediments theme NASA/GCMD Science Keywords NASA GCMD User Support Office gcmduso@gcmd.gsfc.nasa.gov http://gcmd.nasa.gov/MailComments/MailComments.jsf?rcpt=gcmduso GCMD Feedback Form Have a Comment for the GCMD? information custodian http://gcmd.nasa.gov/learn/keyword_list.html GCMD Keywords Page This page describes the NASA GCMD Keywords, how to reference those keywords and provides download instructions. information custodian Environmental Monitoring Sediment Sediment grab geographic information systems GIS Clay Silt Gravel Sand CSC Benthic Habitat Mapping theme None Ocean> Atlantic Ocean > North Atlantic Ocean > Gulf of Mexico place NASA/GCMD Location Keywords NASA GCMD User Support Office gcmduso@gcmd.gsfc.nasa.gov http://gcmd.nasa.gov/MailComments/MailComments.jsf?rcpt=gcmduso GCMD Feedback Form Have a Comment for the GCMD? information custodian http://gcmd.nasa.gov/learn/keyword_list.html GCMD Keywords Page This page describes the NASA GCMD Keywords, how to reference those keywords and provides download instructions. information custodian Virginia Chesapeake Bay York River Catlett Island Goodwin Island place none SHIPS platform NASA/GCMD Platform Keywords NASA GCMD User Support Office gcmduso@gcmd.gsfc.nasa.gov http://gcmd.nasa.gov/MailComments/MailComments.jsf?rcpt=gcmduso GCMD Feedback Form Have a Comment for the GCMD? information custodian http://gcmd.nasa.gov/learn/keyword_list.html GCMD Keywords Page This page describes the NASA GCMD Keywords, how to reference those keywords and provides download instructions. information custodian GRAB SAMPLERS instrument NASA/GCMD Instrument Keywords NASA GCMD User Support Office gcmduso@gcmd.gsfc.nasa.gov http://gcmd.nasa.gov/MailComments/MailComments.jsf?rcpt=gcmduso GCMD Feedback Form Have a Comment for the GCMD? information custodian http://gcmd.nasa.gov/learn/keyword_list.html GCMD Keywords Page This page describes the NASA GCMD Keywords, how to reference those keywords and provides download instructions. information custodian Produced by the NOAA National Geophysical Data Center.

Vertical Positional Accuracy Report Not relevant to data set. All grab data were not included in this data layer. Percent values of sand, silt, clay, gravel, and statistical analyses were included in this data layer. All data are believed to be logically consistent. Field Methods: Grabs for sediments and benthos were collected in May 2004 at a total of 12 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, one sediment subsamples of about 50 g was taken, for sediment grain-size analysis. Samples were placed on ice in the field and frozen in the laboratory until they were analyzed. 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. 2005-01-30T00:00:00 Virginia Institute of Marine Sciences Analytical Services Lab (804) 684-7000 (804) 684-7907 P.O.

A query was developed to review sediment data from all grab sampling stations. A shapefile was created using the field data in the Access database to show spatial trends in sediment distribution in the York River at Catlett and Goodwin Islands. 2005-03-18T00:00:00 NOAA Coastal Services Center CRS Program Manager (843) 740-1200 (843) 740-1224 2234 South Hobson Avenue Charleston South Carolina 29466 U.S.A. processor transferAggregate All datasets were downloaded via FTP.
