Morphology

oceanic + abyss

The phrase is a direct composition of 'oceanic' (relating to the ocean) + 'abyss' (a deep chasm), so a learner who knows both words can readily infer it refers to a very deep depression in the ocean. There is no idiomatic or metaphorical shift and similar constructions exist cross-linguistically, so the meaning is predictable from the parts.

Etymology

Oceanic abyss may come from an old word meaning 'no bottom', and the parts oceanic meaning 'of the ocean' and abyss meaning a very deep pit give a strong picture. So picture a huge, dark hole in the sea floor, which explains why it means 'a very deep part of the ocean'.
