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 ...

The map is the 4.0 version of the International Bathymetric Chart of the Arctic Ocean (IBCAO), an initiative that was created in 1997 in Saint Petersburg (Russia) in order to map the depths of the Arctic floor. Published in digital format, the new chart expands up to 19.6% the submarine ...
Physical Details of Rivers, Lakes and Oceans Ocean depths are shown as five progressively darker blue colors. Light blue areas near the coastlines show shallow water and the approximate extent of the continental shelf. Four progressively darker blues show increasing depth with the darkest blue color...
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....
In this fascinating study, high-definition colour video was captured by sea lions as they swam in the ocean, diving to depths greater than five metres during daylight hours. These cameras, attached to the sea lions, had batteries that allowed for 12–13 hours of total filming, spread ov...

“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 ...
While 71 percent of the Earth is covered by the ocean, less than 15 percent of the ocean floor has been mapped at greater than a 5-kilometer (3.1-mile) resolution. “We havehigher-resolution maps of the entire surface of the Moon, Venus, and Mars than we do of our own planet,” sa...
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 ...
