WB 1318 Underway events, interferometric sidescan sonar of sedimentary processes and benthic habitats, northern margin of the DeSoto Canyon, June 25-29, 2013

The June 2013 interferometric sidescan mapping focused on 3 objectives related to geomorphology, habitat, and sedimentary processes: 1) Conduct a survey of a shelf break canyon that is a study site for circulation modeling (Wienders and Clark group to verify accuracy of.) 2) Survey along the margin, going westward, to assess benthic habitats. Paleoshorelines and/or upper slope habitats are of interest. 3) Conduct surveys of two slope canyon systems that head large sediment-gravity-flow channel systems entering the Desoto Canyon along its northern margin (area generally south of the Pinnacles trend). This dataset contains the underway events from this cruise.
