Table1_GADP_NOSSmoothSheets.csv

This comma-separated value (.csv) table, "Table1_GADP_NOSSmoothSheets.csv," is a derivative table of the information in shapefile "GADP_NOSSeafloorCharacter.zip" included in USGS data release "Gulf of Alaska Digitization Project; Digital seafloor character data from NOS smooth shets" (http://dx.doi.org/10.5066/F7CV4FT9). "Table1_GADP_NOSSmoothSheets.csv" lists the NOS smooth sheets included in the associated shapefile (N = 329, plus insets), the number of samples for each smooth sheet, the year of collection (1892 to 2001), and the smooth sheet scale (from 1:2,000 to 1:600,000). Smooth sheets are available through the National Geophysics Data Center’s online data portal (NDGC, http://www.ngdc.noaa.gov).
