Eelgrass Beds 93-95 Observed Polygon
type: Dataset
description: Eelgrass Beds 93-95 Set: Eelgrass Sample Points is a 1:24,000-scale, point feature-based layer that depicts the locations where eelgrass (Zostera marina) was either observed or where a location would be potentially favorable for future eelgrass growth. Sample points were taken along Connecticut's coast in Long Island Sound, and in major bays, harbors and rivers along the shoreline. The point features in this layer were compiled from field research using global positioning system (GPS) equipment. Feature locations were not always exact due to equipment failure or lack of satellite reception. In those cases, points were estimated from field notes. Some point locations were corrected based on field notes or hydrography and bathymetry conditions at the sample point location. The number of field points that were altered were as follows: In 1993, 32 of 290 points (11%); in 1994, 93 of 454 points (20%); in 1995, 37 of 105 points (35%). Data compilation occurred on 17 days between 7/21/1993 and 11/16/1995; exact dates of each source's data collection are noted in the attribute table. A total of 849 point locations were surveyed. The westernmost point is Frash Pond in Stratford, Connecticut and the easternmost point is the Pawcatuck River on the Connecticut/Rhode Island Border. Eelgrass was found at 484 locations and was described as either high, medium, or low density, or simply as present or absent. Eelgrass was absent at 365 locations. Publication of the datalayer was in 1997. This layer is not updated. This layer does not represent current conditions. 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 re…
