This bathymetry map of Pauline Cove on Herschel Island, Yukon Territory, Canada, serves as a baseline for long-time studies by the Alfred Wegener Institute for Polar and Marine Research (AWI) in Germany. The area was chosen as the natural laboratory for coastal erosion processes in permafrost regions. Kongsberg Geoacoustics GeoSwath Plus compact system was used for the seafloor mapping. The system delivers high resolution bathymetry with coverage of up to 12 times the water depth in this shallow water environment. Note the dredge marks caused by sea ice processes.
