Sidescan-sonar imagery, originally collected by NOAA for charting purposes, provide a fundamental framework for research and management activities along this part of the Massachusetts coastline, show the composition and terrain of the seabed, and provide information on sediment transport and benthic habitat. While acceptable for charting purposes, the original data contained numerous tonal artifacts due to environmental conditions (such as sea state), variable system settings (such as gain changes), attitude variations in the flight path of the towfish, or processing (such as lack of line to line normalization). Many of these artifacts have now been removed by enhancing the imagery to provide a more continuous grayscale GeoTIFF that enhances the true backscatter character and trends of the sea floor. Purpose: To release an enhanced GeoTIFF image of the 1-meter, 455-kHz sidescan-sonar data generated during NOAA survey H11079 in Great Round Shoal Channel, offshore Massachusetts, in UTM Zone 19, NAD83.

Process_Step: Process_Description: Adjacent lines that were of an unnatural and abruptly different tone were adjusted by tracing the perimeter of the line with the Polygon Lasso Tool and then matching tones to the adjacent lines with the shadow, mid-tone, and highlight input sliders in the Levels dialog box of Adobe Photoshop 7.0. Lines that were too light (based on comparisons with adjacent lines and with the verification data) were darkened; lines that were too dark were lightened.
