Hudson Bay (Inuktitut: Kangiqsualuk ilua, French: baie d'Hudson) is a large body of saltwater in northeastern Canada with a surface area of 1,230,000 square kilometers. It is the second-largest bay in the world, after the Bay of Bengal. The bay is relatively shallow and is considered an epicontinental sea, with its average depth being around 100 meters. Hudson Bay is named after the English explorer Henry Hudson who, in 1610 on his ship the Discovery, was searching for a northwest passage to Asia. The bay's extensive drainage basin covers over 3,861,400 square kilometers, including parts of Ontario, Quebec, Saskatchewan, Alberta, most of Manitoba, southeastern Nunavut, as well as parts of North Dakota, South Dakota, Minnesota, and Montana, making it a significant geographical feature in North America.

Geography

Hudson Bay is bordered by Ontario to the south, Quebec to the east, and Nunavut to the north. It connects to the Atlantic Ocean via the Hudson Strait and the Labrador Sea. The coastline is characterized by lowlands and is home to numerous rivers that drain into the bay, including the Nelson River, Churchill River, and the Great Whale River. The bay's northern and eastern shores are lined with tundra and permafrost, while its southern shores are part of the boreal forest biome.

Climate

The climate around Hudson Bay is generally classified as subarctic. Winters are long and cold, with temperatures often dropping below -30°C, while summers are short and cool, with temperatures rarely exceeding 20°C. The bay itself freezes over from about mid-November to mid-June, significantly influencing the regional climate by cooling the summers and moderating the winter temperatures.

Ecology

Hudson Bay's ecosystem is rich and diverse, supporting a variety of marine life, including polar bears, seals, walruses, and over 200 species of birds. It is also a critical habitat for beluga whales and the endangered bowhead whale. The surrounding land areas are inhabited by animals typical of the northern boreal forest and tundra, such as caribou, wolves, and foxes. The bay's ecological significance is recognized by several conservation areas established around its perimeter.

History

The first European to reach Hudson Bay was likely Henry Hudson in 1610, though the bay had been inhabited by Indigenous peoples for thousands of years before his arrival. Hudson's exploration opened the region to European fur traders, particularly the Hudson's Bay Company (HBC), which was granted a charter by Charles II of England in 1670, giving it control over the waterways leading into the bay and a trade monopoly in the area. This led to the establishment of trading posts and significant European influence in the region. The fur trade dominated the economy of the Hudson Bay region for centuries, with control of the territory being a contentious issue between the British and the French until the Treaty of Utrecht in 1713, which ceded control of the surrounding lands to Britain.

Economy

Today, the Hudson Bay area's economy is primarily based on mining, fishing, and hydroelectric power. The bay is also an important transportation route for goods, particularly in the summer months when it is ice-free. Climate change poses a significant threat to the region, affecting ice cover, sea levels, and the habitats of various species.

Conservation

Efforts to preserve the unique ecosystems of Hudson Bay focus on combating climate change, protecting wildlife habitats, and regulating industrial activities. Several national parks and wildlife areas have been established around the bay to protect its natural heritage.
