PhD position opportunity at Stockholm university - Sea floor mapping using multibeam backscatter in the Arctic and Antarctic
http://www.geo.su.se/images/stories/pdf/phd_marine_geo_gyllencreutz_en.pdf

Project description
The project is aimed to use backscatter data for mapping seafloor surface sediments. The term backscatter refers to the intensity of reflected signals from a multibeam echo sounder or side-scan sonar. The project will utilise existing data collected with icebreaker Oden's multibeam system from shelf and deep sea areas in the Arctic and Antarctic, as well as new data, to be collected during a planned expedition to the Arctic in 2012. The results from the backscatter analyses are to be evaluated against measured physical and chemical properties of sediment samples. The project is interdisciplinary between geophysics and sedimentology. Processing of backscatter data shall be developed to facilitate the interpretation of formation processes of glacial land forms, especially regarding the role of the bed substrate in areas showing signs of former ice streams. The project will be carried out in a group working with ice sheets, ice shelves, and sea ice, and their connections with the paleoceanographic and paleoclimatic development in both the Arctic and Antarctic.
