- Ungava Bay (French: baie d’Ungava, pronounced [bɛ d‿œ̃ɡava]; Inuktitut: ᐅᖓᕙ ᑲᖏᖅᓗᒃ/ungava kangiqluk) is a bay in northeastern Canada separating Nunavik (far northern Quebec) from Baffin Island. Although not geographically apparent, it is considered to be a marginal sea of the Arctic Ocean for climatic reasons. The bay is roughly oval-shaped, about 260 kilometres (160 mi) at its widest point and about 320 kilometres (200 mi) in length; it has an area of approximately 50,000 km2 (19,000 sq mi). It is generally fairly shallow, under 150 metres (490 ft), though at its border with the Atlantic Ocean depths of almost 300 metres (980 ft) are reached.
