Ungava Bay (French: baie d'Ungava,
ᐅᖓᕙ ᑲᖏᖅᓗᒃ/ungava kangiqluk) is a large bay in
Nunavik (far northern Quebec) from
Baffin Island. The bay is roughly oval-shaped, about 260 km
(160 mi) at its widest point and about 320 km (200 mi)
in length; it has an area of approximately 50,000 km2
(19,000 sq mi). It is generally fairly shallow, under
150 m (490 ft), though at its border with the Atlantic Ocean
depths of almost 300 m (980 ft) are reached.

There are a number of islands within Ungava Bay. The largest, Akpatok
Island, and others north of 60°N are part of the territory of
Nunavut, while smaller islands south of 60°N belong to Quebec.
Although it is quite close to the open Atlantic (separated only by
Ungava Bay is generally considered part of the Arctic
Ocean because the land surrounding it has an exceedingly cold climate.
Ungava Bay is separated from
Hudson Bay by the Ungava Peninsula.
Bathymetric studies suggest
Ungava Bay may be the remnant of an impact
crater (age unknown) approximately 225 km in diameter.
The southwestern corner of Ungava Bay, along with Bay of Fundy, has
either the highest or second-highest tidal ranges in the world.
Some sources estimate the spring tide range at the mouth of the Leaf
River as being as high as 17 m (56 ft). Attempts have been
made to develop tidal power in the bay, but this is made difficult by
the harsh climate and the fact that the bay is ice-free for only a
small part of the year.
Due to the influence of the Labrador Current, summers are too cold for
tree growth and all the land surrounding the bay is treeless tundra.
Typically, temperatures in summer at
Kuujjuaq about twenty kilometres
Koksoak River are about 7 °C (45 °F), while winter
temperatures are about −20 °C (−4 °F). Precipitation
averages around 400–450 mm (16–18 in) per year, most of
it falling in the summer.
Ungava Bay is surrounded by numerous
Inuit villages, the largest of
which is Kuujjuaq, Quebec, at the mouth of the Koksoak River. Iron ore
has been mined in the past, but despite the high grade of the ores the
impossibility of cheap transportation meant that mining was
discontinued in 1980. Traditional
Inuit hunting activities still
dominate the region's life, along with expensive adventure tourism.
