Bathymetry

The measured shape and depth of the sea floor.

Oak Island money pit

Loch Ness

Malaysia Airlines Flight MH370

The underwater equivalent of a map's contours, made with echo sounders from ships. A search for a lost ship or aircraft needs it first, because sonar and cameras work differently on flat sediment, slopes and rock, and because what sank comes to rest where the floor lets it. Much of the MH370 search area was mapped for the first time in order to search it.
