sinus

Astronomy

An indentation in the edge of high ground on the surface of a planet or satellite; pl. sinūs. The name, which means ‘bay’, is not a geological term but is used in the nomenclature of individual features, for example Sinus Iridum on the Moon. It is also used for a protrusion from a dark area in the naming of Martian albedo features, for example Sinus Meridiani. On Titan the name is used for bays around areas of liquid hydrocarbons, for example Moray Sinus.

Biology

Geology and Earth Sciences

A Latin word meaning ‘curve’ or ‘bay’.
1. The word ‘sinus’ was used by Giovanni B. Riccioli in 1651 to designate bay-like features on the lunar maria (see mare). The best known example is Sinus Iridum, the ‘Bay of Rainbows’, on the north-western margin of the ‘Sea of Rains’ (Mare Imbrium).
2. In certain bivalves (Bivalvia), a recess or embayment in the pallial line; most bivalves with a pallial sinus are burrowers.
