Morphology

oceanaut = ocean + naut (semi-transparent) = ocean + naut

The component 'ocean' clearly indicates the domain, but 'naut' is a less familiar combining form (not a productive standalone word), so the meaning is only partially guessable by average learners.

Etymology

Oceanaut joins ocean and naut, where naut comes from an old Greek word meaning 'sailor' and is the same part you see in astronaut. So an oceanaut is like a 'sailor' of the sea who lives and works under the water.
