Ungava Bay (
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.
Geography
Although it is quite close to the open Atlantic (separated only by Hudson Strait), Ungava Bay is part of the Arctic Ocean. Ungava Bay is separated from Hudson Bay by the Ungava Peninsula. Akpatok Island is largest of the many islands in Ungava Bay. Bathymetric studies[by whom?] suggest that Ungava Bay may be the remnant of an impact crater (age unknown) approximately 225 km (140 mi) in diameter.
The southwestern corner of Ungava Bay vies with 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 study the potential for producing electricity using tidal power in the bay,[2][3][1]
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.
Climate
Due to the influence of the
Precipitation
averages around 400–450 mm (16–18 in) per year, most of it falling in the summer.
Human development
Ungava Bay is surrounded by numerous
Kuujjuaq, 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 adventure tourism
