These studies have built upon cooperative research with the State of Connecticut that was initiated in 1982. This research program is currently studying sea-floor sediment distribution, processes that control sediment distribution, nearshore environmental concerns, and the relation of benthic community structures to the sea-floor geology. Detailed maps of the sea floor are needed to aid in interpretation of the sea-floor geology. Therefore, sidescan-sonar data have been collected in areas of interest. Although these mosaics from NOAA surveys H11043, H11044, and H11045 in north-central Long Island Sound have been interpreted in prior reports, we have enhanced these three mosaics in order to minimize tonal artifacts created by the mismatching of backscatter in adjacent track lines. The enhanced mosaics provide a clearer image of the sea-floor geology. Purpose: This GIS overlay is a component of the H11043 survey GIS database in north-central Long Island Sound off Branford, Connecticut. This image represents the completed enhanced sidescan-sonar mosaic for the study area. Light tones represent relatively harder returns, higher backscatter, and generally coarser sediments. Dark tones represent relatively softer returns, lower backscatter, and generally finer grained sediments. This mosaic covers 41.1 square km of the sea floor.

Process_Step: Process_Description: Tonal artifacts were minimized in a previously published sidescan-sonar mosaic. The tonal range of individual sonar lines was adjusted by tracing the perimeter of the line with the Polygon Lasso Tool and then matching tones to the adjacent lines with the shadow, midtone, and highlight input sliders in the Levels dialog box of Adobe Photoshop CS2. The Spot Healing Brush Tool was used in several places to eliminate small artifacts within a sonar line.
