Over the summer of 1999 and 2000, eelgrass was mapped within Ninigret Pond using field notes, GPS, digital orthophotography and line-intercept transects. Initial delineations were done by field reconnaissace of the entire shoreline by boat. Exsisting beds of eelgrass were transcribed onto enlarged field copies of USGS Topographic maps. Further delineations were based on GPS and line-intercept point data sets. The result is a polygon data set showing the remaining eelgrass bed within Ninigret. Purpose: The data was collected as a portion of a master's thesis. Supplemental_Information: Bradley, M.P. In Press.
