Coastal waters of southwestern Alaska the Baja California Peninsula, Mexico contain extensive beds of seagrass (eelgrass: Zostera marina and widgeongrass: Ruppia marina). Provided here are vector and raster geospatial datasets that characterize the distribution of seagrass, seaweeds, and other coastal habitats in waters adjacent to five National Wildlife Refuges in Alaska (Togiak, NWR, Izembek NWR, Alaska Peninsula-Becharof NWR, Alaska Maritime NWR, and Yukon Delta NWR) and five bays along the west coast of the Baja California Peninsula (Bahia San Quintin, Laguna Ojo de Liebre, Estero Coyote, Laguna San Ignacio, and Estero San Juanito). These data were derived from ortho-rectified aerial photo imagery and satellite imagery (Landsat 5 TM, Landsat 7 ETM+, Ikonos-2, and Quickbird-2).
