The Dataset's Variables and Attributes

Row Type Variable Name Attribute Name Data Type Value
attribute NC_GLOBAL cdm_data_type String Grid
attribute NC_GLOBAL comment String This layer classifies soft-sediments based on their grain size. Source data include USGS usSeabed: Atlantic coast offshore surficial sediment data (Data series 118, version 1.0) and the USGS East Coast Sediment Texture Database (2005), Woods Hole Coastal and Marine Science Center. Point-based data were interpolated using krigging tools to create this layer. Resulting values were classified based on grain-size according to the Wentworth (1922) scale. This classification process resulted in the following classes: clay (< 0.002 mmm), silt (0.024 - 0.06), very fine sand (0.06 - 0.125 mm), fine sand (0.125 - 0.25 mm), medium sand (0.25 - 0.5 mm), coarse sand (0.5 - 1.0 mm), very coarse sand (1 - 2 mm), and Gravel/granule (> 2 mm). Finally, point data was interpolated using kriging to create the resulting raster layer. The spatial resolution of this layer is 500 meters.

attribute NC_GLOBAL summary String This dataset was created for the Northwest Atlantic Marine Ecoregional Assessment (NAMERA) in order to map soft sediments based on their grain size (in mm). This version (2) is an update of the original 2010 soft sediments layer using new data. THIS DATASET WAS NOT CREATED FOR NAVIGATIONAL PURPOSES AND AS SUCH SHOULD NOT BE USED FOR NAVIGATION.
