subaqueous

Beneath the water

Subaqueous means existing, formed, or taking place underwater: subaqueous volcanic eruptions, subaqueous sediment deposits.

The word appears mainly in scientific and technical writing—geology, marine biology, engineering.

It's interchangeable with underwater in most contexts but carries a more formal, Latinate tone.
