Bathymetry is the study of the underwater depth of sea and ocean floors, lake floors, and river floors. It has been carried out for more than 3,000 years, with the first recorded evidence of measurements of water depth occurring in ancient Egypt. Bathymetric measurements are conducted with various methods, including depth sounding, sonar and lidar techniques, buoys, and satellite altimetry. However, despite modern computer-based research, the depth of the seabed of Earth remains less well measured in many locations than the topography of Mars. Bathymetry has various uses, including the production of bathymetric charts to guide vessels and identify underwater hazards, the study of marine life near the bottom of bodies of water, coastline analysis, and ocean dynamics, including predicting currents and tides. This video, created by the Scientific Visualization Studio at NASA's Goddard Space Flight Center, simulates the effect on a satellite world map of a gradual decrease in worldwide sea levels. As the sea level drops, more seabed is exposed in shades of brown, producing a bathymetric map of the world. Continental shelves appear mostly by a depth of 140 meters (460 ft), mid-ocean ridges by 3,000 meters (9,800 ft), and oceanic trenches at depths beyond 6,000 meters (20,000 ft). The video ends at a depth of 10,190 meters (33,430 ft) below sea level – the approximate depth of the Challenger Deep, the deepest known point of the seabed.Video credit: NASA / Goddard Space Flight Center / Horace Mitchell, and James O'Donoghue

Hello Sunborn
[edit]I made some edits to a page you had previously worked on. My comments about the recent round of edits to the List of Zeta Psi chapters is on the Talk page. If you have continuing interest and time, I'd welcome your review. You'd also be welcome to join the Fraternities and Sororities Project. If I read correctly your reasons for semi-retiring, I concur that edit wars and Deletionism has been a problem. For us, we police these articles within our area of interest, and have kept the Deletionists and other trolls at bay. We now monitor several thousand pages, and are actively improving them.

[edit]As a fellow engineer, I believe that you should undo removal of [[Category:Wikipedian engineers|Sunborn]]
