ocean floorGiven the depth of 14 arbitrary points in a rectangular region of the ocean. our team created detailed three-dimensional and two-dimensional grid and contour maps that clearly highlighted dangerous shallows. Because the ocean floor was assumed to be smooth and without cliffs, the team ...
As this map of South Asia and the Himalayas shows, plan oblique relief contains vertical offset. Starting from the datum at sea level, terrestrial mountains project upward toward the top of the map and ocean depths project downward. The graticule is accurate only at sea level....

“PASS could be used to map the depths of uncharted waters, survey biological environments, search for lost wreckages, and potentially much more,” he said. “Isn’t it strange,” he added, “that we have yet to explore the entirety of the Earth we live on? Maybe PASS can change ...
Yet, the specifics of SAR imaging mechanisms require a particular alertness in the task of interpreting SAR imagery of the ocean and the coastal areas in particular. The most significant environmental feature of the near-shore region is that water depths are shallow and change rapidly. The ...
of sound pulses to and from the ocean floor, which returns depths (bathymetry), or to measure the intensity of those sound pulses as they return, which yields backscatter imagery of the seafloor (akin to a hillshade or an aerial photograph). The instruments deployed at the surface of the ...
