isothermobath
Very LowTechnical/Scientific
Definition
Meaning
A line on a map or chart connecting points in a body of water having the same temperature at a given depth, or connecting points where the temperature is the same at the same depth.
In oceanography and climatology, it is a contour line used to visualize the three-dimensional thermal structure of oceans or large lakes, showing horizontal temperature distribution at a specific depth.
Linguistics
Semantic Notes
A highly specialized term composed of Greek roots: 'iso-' (equal), 'thermo-' (heat/temperature), and 'bath' (depth). It is a concept rather than a physical object, exclusively used in the domain of physical geography and oceanography.

Examples
By CEFR Level
- This word is too difficult for A2 level.
- Scientists sometimes draw special lines on maps to show water temperature.
- Oceanographers use charts with lines called isothermobaths to understand temperature distribution at different depths.
- The analysis revealed that the 4°C isothermobath at 500 metres had shifted significantly northward due to the current anomaly.
Learning
Memory Aids
Mnemonic
Imagine an ISOtherm (equal temperature) taking a BATH at a certain depth in the ocean. That's your ISOTHERMOBATH.
Conceptual Metaphor
A thermal roadmap for the ocean's depths.
Watch out
Common Pitfalls
Translation Traps (for Russian speakers)
- Do not confuse with 'изотерма' (isotherm), which is for surface temperature. 'Isothermobath' includes the depth element ('bath-').
- The '-bath' part is from Greek 'bathos' (depth), not related to bathing.
Common Mistakes
- Misspelling as 'isothermobath' (missing 'o') or 'isothermobath'.
- Using it to refer to surface temperature lines (those are 'isotherms').
- Pronouncing the '-bath' as in 'bathtub' instead of /bɑːθ/ or /bæθ/.

FAQ
Frequently Asked Questions
No, it is an extremely rare technical term used only in specific scientific fields like oceanography.
An isotherm connects points of equal temperature, typically at the surface (e.g., on a weather map). An isothermobath specifically connects points of equal temperature at the same depth in a body of water.
It would be highly unusual and likely confusing, as it is purely a specialist scientific term.
In British English: /ˌaɪ.səʊ.ˈθɜː.məʊ.bɑːθ/. In American English: /ˌaɪ.soʊ.ˈθɝː.moʊ.bæθ/. The stress is on the third syllable ('ther').
