| Summary: | Multibeam Sonar image of the wreck of the Lusitania Hydrosweep is used to map the topography of the ocean’s floor in 2-D and at a high resolution. Such data is crucial for several research fields and environmental studies within the oceanic environments: � To identify and map sites of environmental importance such as cold water coral reefs or seamounts. � To determine in-situ the exact site for oceanographic, geophysical, climatological or biological studies, such as deep water passages, sediment layers or ice-berg grounding tracks. � To develop reliable navigational charts, particularly in remote areas, for commercial navies and tourism. Comparison of topographic from IBCAO- the best currently available Arctic chart (smooth contour lines)- and from a RV Polarstern Hydrosweep survey (wiggly contour lines) near Gakkel Ridge/Lena trough (83°N, 3°W). Contour lines every 100m. � Pulse lengths and the dual criterions: |
