Count Component Title Abstract
1 AFSC/RACE/GAP/McConnaughey: Trawlex Chronic Effects: Side Scan Sonar Mosaic - NE corner of CHPZ1. Side-scan sonar images were collected using a Klein 2000 system and a 100/500-kHz towed ?sh that also contained a 3.5-kHz pro?ler source. A shipboard fathometer re- cording system was inoperable during the survey. The side-scan data were recorded digitally at a 10-kHz sample rate over a swath width of 100 m. Six swaths of 100-kHz data were anamorphosed, filtered, overlaid and projected to produce a spatially correct, georeferenced image of the seafloor with pixel resolution of 80 cm.

        1 Side-scan sonar images were collected using a Klein 2000 system and a 100/500-kHz towed ?sh that also contained a 3.5-kHz pro?ler source. The side-scan data were recorded digitally at a 10-kHz sample rate over a swath width of 100 m. A single line of 100-kHz data was anamorphosed, filtered, overlaid and projected to produce a spatially correct, georeferenced image of the seafloor with pixel resolution of 80 cm. Grey scale stretch was applied to the data for visual aesthetics. Data were processed using USGS MIPS, where an img and lbl and file was created. The img and lbl file were then converted to bil and hdr format.
        1 The bil and hdr file were imported into a raster file geodatabase in ArcGIS and assigned a projection
