From Glossary of Meteorology


  1. An abbreviation used informally for terms such as "bathymetric," "bathythermal," or "bathythermograph."

  2. In all uppercase (BATHY), the name of the World Meteorological Organization traditional alphanumeric code (TAC) form for reporting bathythermal observations. (Weather and oceanic data are communicated over national and international communications circuits as coded messages. Messages in TAC are broken into groups of related information, and BATHY is the shorthand used in TAC documentation to refer to the code form used for reporting a bathythermal observation.)

  3. Derivative from meaning 2, bathy or BATHY is sometimes used informally to refer to a bathythermal observation in a context other than a TAC message.
