Locations are based both on coordinates provided by field staff (gathered either by geographic positioning system [GPS] or by using navigation charts to ascertain latitudes and longitudes) and maps provided by the field staff. Fish and Wildlife Research Institute (FWRI) GIS staff in the Marine Mammal subsection verify that the provided coordinates match the intent of the plotted location. Points representing carcass locations were entered into a GIS using a digital shoreline basemap taken largely from NOAA navigation charts (1:40,000) and from USGS quadrangles (1:24,000). The scale is considered to be 1:40,000.
