Description
Provided here are two vector geospatial datasets that characterize the distribution of: (1) eelgrass (Zostera marina) and (2) seaweeds in waters adjacent to four National Wildlife Refuges in Alaska (Izembek NWR, Alaska Peninsula-Becharof NWR, Alaska Maritime NWR, and Yukon Delta NWR). These data were derived from satellite imagery (Landsat 5 TM and Landsat 7 ETM+) acquired on four different days (2002-08-02, 2006-07-20, 2007-06-04, 2009-08-04). After pre-processing, imagery was classified into land cover categories (eelgrass, seaweed, mud/sand, and channel). The eelgrass and seaweed distribution data were then extracted from the raster grid and converted to vector data.
