Data was collected from personal interviews, herbarium specimans, literature reviews, and NOS charts, and ranged from 1848-1994. Applied Science Associates digitized the data into ASAMAP GIS, but no metadata was documented at the time. This 2000/2001 dataset is a result of importing the ASAMAP GIS datasets into ArcView and consolidating the files into one shapefile.

Data was digitized into ASAMAP GIS. Locations of herbarium specimans were digitized into ASAMAP GIS as points. Literature citations were digitized into ASAMAP GIS as points. Oral interviews were conducted with 12 people from either the RI Shell Fisherman's Assoc. or the RI Divers Assoc. Each person was asked to describe the organisms they saw in the grass beds, the activities that people were involved with inside the grass beds, describe the locations, dates of existence, depths, and possible causes for decline of eelgrass beds. The interviewees drew the locations of the eelgrass beds on a NOAA chart of Narrgansett Bay. Each location that a person described was assigned a reliability score on a scale of 1-3 with 1 being the least reliable and 3 being the most reliable. Data were plotted using ASAMAP GIS. In October, 2000, the above datasets were converted from ASAMAP into ArcView shapefiles by Applied Science Associates. The resulting 12 datasets were eventually merged into one shapefile. Two additional attributes, "YEAR" and "TYPE", were added to the final shapefile to aid in data analysis and were coded directly from the attribute "NAME".
