The thinking was using 'water_body' as an adjective specifying the type of 'water'. We could equally well have 'ground_water', 'cloud_water','rain_water' and so on. It was not to specify different types of temperature within the water body.

I wasn't sure why the term becomes 'water_body_water_temperature' and not just 'water_body_temperature'.
The analogous term sea_water_temperature seems to be redundant as to the medium, a 'sea' always being water. I assumed this just developed from common usage, people just called it 'sea water' (distinguishes from sea salt, sea life, but in this context 'sea_temperature' would have carried the semantic content) and therefore so did CF.
Are we running into an issue because these terms are being used both for the medium, and for a position description (in an X, Y location that is over/in/under a sea)? So you might have 'water_body_air_temperature'?
