Data
NOAA CSC Benthic Grab Sample Data
Produced and distributed by the NOAA Coastal Services Center
The National Oceanic and Atmospheric Administration (NOAA) Coastal Services Center's grab sample data are collected using a variety of small grab sampling devices (such as Ponar and Shipek). The data represent benthic habitats observable at the time of data collection. The grab samples fall into two types: a sediment grab focused on sediment grain size analysis; and a benthic grab focused on identifying biota within the sample.
Data Specifications
- Area of Coverage: Varies by project. Normally ranges from minimum depths of -1 meter to -30 meters. Project extents are individual bay systems in Maine, Virginia, New York, New Jersey, and Florida.
- Date(s) Available: Vary by location, ranging from 1995 to 2004
- Format: ESRI point shapefile
- Resolution: Planimetric resolution is based on the size of the grab and normally is approximately .03 meters. Vertical resolution is dependent on substrate type but normally is less than 0.25 meters.
- Accuracy: 100 percent for observed points
