Observed Eelgrass 1993-95
Observed Eelgrass Beds is a 1:24,000 scale, polygon feature-based layer that depicts the locations of observed eelgrass beds in Long Island Sound, in major rivers, and within bays, harbors and other waterbodies along Connecticut's coast.  The layer is based on information from the Eelgrass Sample Points layer.  It represents conditions at a particular point in time (1993 to 1995).  During the 1993-95 field seasons a team of researchers from the University of Connecticut Dept. of Ecology and Evolutionary Biology led by Charles Yarish, equipped with a Global Positioning System (GPS), SCUBA, and a 20' boat surveyed over 800 potential eelgrass locations.  Their GPS coordinates and field notes were used to create a point coverage entitled Eelgrass Sample Points, which was plotted and checked on a 1:24000 scale base map of the Connecticut shore.  These point locations, observations, and the nearshore bathymetry were then used to delineate areas representing both observed and potential eelgrass beds.  Eelgrass beds were initially digitized at 1:24,000 scale, but have been edited and revised on screen at higher resolution.  Keeping in mind the temporal and spatial variability of eelgrass, beds may vary in size, shape, and density from year to year.  

Feature locations may not always be exact due to equipment failure or lack of satellite reception.  In those cases, points were estimated from field notes.  It should be noted that the Observed Eelgrass Beds layer is not a complete dataset of all observed eelgrass sites in Connecticut and/or Long Island Sound.  This layer was published in 1997 and is not updated.  It does not represent current conditions.
