Abstract:
This GIS layer shows the extent of the area covered by the sidescan sonar mosaic from the study area off New London, CT.
Purpose:
This GIS layer, which focuses on benthic communities, was developed as part of a cooperative project between the University of New Haven, the Connecticut DEP, and the U.S. Geological Survey. Benthic communities are an integral component of the ecology of LIS.
 
Understanding the role that spatial heterogeneity plays in the dynamic of benthic landscapes may be a key to developing a better understanding of the estuarine ecology and the impacts of huuman activity. The purpose of providing this data layer is to help establish a regional framework for developing a more extensive GIS for benthic communities in LIS that can be used for education, research, and environmental management.

Process_Step:
Process_Description:
Mapping was performed on a sidescan sonar survey. This survey was processed at 3,479-scale utilizing the U.S.G.S. Mini Image Processing system (MIPS) in an Equatorial Mercator Projection. Processing included bottom, ratio, and radiometric corrections; sectioning the survey area; "Geoming" individual map sections; "stenciling" and "mosaicing"; and building the final image. The shading convention for this mosaic is that dark tones are interpreted as fine sediment (fine sand, silt and clay); and light tones are interpreted as coarse sediment. Rough and "grainy" patches are interpreted as glacial drift or bedrock outcrops. The image files contained here have been modified, using Arc/Info software, from the three original TIFFs delivered by University of Rhode Island. The images were converted to grids, geo-referenced, and individually reclassified in a manner similar to linear stretching to account for variations in gray scales among the three sections of the mosaic. The grids were then converted back to TIFF format with world files in Latitude/Longitude decimal degrees (no projection). Pixel size is approximately 0.8 meters.
