bathymetry
Aug. 4th, 2021 07:52 ambathymetry (bbuh-THIM-uh-tree) - n., the measurement of the depth of (a body of water).
Could be ocean or lake, though usually the former -- the underwater equivalent of topography. Or the measurements that create the underwater equivalent, or something like that. When a ship makes a sounding to make sure it won't run aground ("By the mark four!") it's doing bathymetry. Coined in the 1850s from Ancient Greek roots bathús, deep + métron, measure.
