Survey-room shorthand for bathymetric data and products. People speak of bathy surfaces, bathy files, the bathy deliverable and bathy versus imagery, where imagery means side-scan or backscatter. On multidisciplinary jobs the bathy crew is the team running the echo sounders, as distinct from those running magnetometers or sub-bottom profilers.
Send the client the bathy at 1 metre and the backscatter mosaic at 25 centimetres.
