In the concept of physical geography, the marginal sea that is deep into the interior of the continent, communicates with the ocean only has a narrow waterway, and the hydrological characteristics are deeply affected by the climate of the surrounding continents, we call it "inland sea", such as China's Bohai Sea is a typical inland sea. The inland sea is part of a country's internal waters, which include seaports, seas within the baseline of the territorial sea, as well as bays and straits leading to the sea surrounded by land but with narrow entrances. All States in the inland sea have the right to close the inland sea and prevent the entry of ships of other States, and the rules of navigation established by them must be observed by ships of other States. In Canada, there is a similar "quasi-inland sea", which is more than ten times the size of the Bohai Sea, that is, Hudson Bay.
Canada also has a "quasi-inland sea", which is more than ten times the size of the Bohai Sea, that is, Hudson Bay.
The world's largest inland shallow sea
Hudson Bay (English name: Hudson Bay), also translated as Hudson Bay, is located in northeastern Canada, the northeast corner is connected to the Atlantic Ocean through the Hudson Strait, labrador Sea and the Atlantic Ocean, and the north side is connected to Fox Bay and connected to the Arctic Ocean through the waterway at its northern end, so Hudson Bay is also the edge sea of the Arctic Ocean. Hudson Bay penetrates deep into the North American continent, with a length of about 1,375 kilometers from north to south, a width of about 960 kilometers from east to west, and an area of up to 819,000 square kilometers, making it the world's largest nearly enclosed shallow inland sea.
Hudson Bay is deep into the North American continent, about 1375 kilometers long from north to south, about 960 kilometers wide from east to west, with an area of 819,000 square kilometers, making it the world's largest inland shallow sea.
Hudson Bay average depth of about 100 meters, the maximum depth of 274 meters, north and west is Canada's Newnavut region, mostly located in 60 degrees north and south latitude, although only a small part is located in the Arctic Circle, but the inland Hudson Bay is deeply affected by the continental climate, the winter is long and cold, the summer is cool and short, the average annual temperature is only -12.6 °C, the average temperature in January is -29 °C, and the average temperature in July is 8.3 °C. Ice freezes often occur in October, with snowstorms, and the ice begins to recede until May of the following year, but does not completely melt until July and August, resulting in ice and ice floes in the bay for most of the year.
Deep inland, Hudson Bay is deeply influenced by the continental climate, with long and cold winters and cool and short summers, with an average annual temperature of only -12.6 °C.
Ice freezes occur in October, with frequent snowstorms, and the ice begins to recede until May of the following year, but does not completely melt until July and August.
Regional low temperatures give here almost the same length of ice as the high latitudes within the Arctic Circle, and coupled with the strong tidal influence of the Labrador coast, the current carries ice floes from Fox Bay in a counterclockwise direction into the bay, out of the Hudson Strait, into the Labrador Cold Current. Moreover, Hudson Bay is generally in the subpolar rainy zone, resulting in frequent foggy weather in the bay, which is foggy for about 300 days a year. Only the long hours of sunshine in the summer guarantee that the bay is sunny, and this is also the golden season of Port Churchill.
The Earth Shield, also known as the Craton, points to the exposed ancient land core, while the Canadian Shield is the exposed part of the Precambrian crystalline substrate and is the "old ancestor" of the formation.
The Hudson Bay Lowlands are canada's largest plains, and together with Hudson Bay, it is part of the fall of the world's largest Canadian Shield.
Port Churchill, located within Hudson Bay, is an important port in northern Canada, mainly exporting wheat from the Hudson Bay Lowland Plains (600,000-700,000 tons per year), of which a considerable part is said to be shipped to China. By extension, this Hudson Bay lowland, canada's largest plain, is part of the fall of the world's largest Canadian shield, along with Hudson Bay. The so-called earth shield, also known as the craton, points to the ancient land core of the dew, while the Canadian shield is the exposed part of the precambrian crystalline base, which is the "old ancestor" of the formation, recording the appearance of the early formation of the earth's crust.
The Canadian Shield covers about half of Canada' area, and the rocks here are extremely old-lived, with deep drilling to detect rock samples showing billions of years.

The Canadian Shield covers about half of Canada's area, and the rock life here is extremely old, with deep drilling sampling showing billions of years, and 4.567 billion years is currently recognized by geology as the age of crust formation. The Hudson Bay and Hudson Bay lowlands have been in a slump since the Lower Paleozoic Era, and the Quaternary period has been sunk by the pressure of glaciers, so the terrain is very low. This lowland area of more than 300,000 square kilometers (equivalent to three Jiangsu provinces), with abundant precipitation, rivers and swamps, is a good place for agricultural development, the only fly in the ointment is the cold climate and insufficient accumulated temperature.

The cold Hudson Bay is a rare sanctuary for polar bears.
A sanctuary for polar bears
Of course, the cold Hudson Bay is a rare sanctuary for polar bears. Port Churchill, where the average annual temperature is only -5°C, is said to be home to more than 1,000 polar bears in late autumn each year, waiting for Hudson Bay to freeze and migrate to the Arctic. So there's an alternative law: all buildings and vehicles are not allowed to be locked at any time, so that people who happen to encounter polar bears outdoors can enter the building or hide in the car at any time.
Hudson Bay brings together a large amount of fresh river water, making the sea ice point here close to 0 °C, which is slightly higher than the sea at the same latitude.
The reason why Hudson Bay is a sanctuary for polar bears is that Hudson Bay brings together a large amount of river fresh water, so that the sea ice point here is close to 0 ° C, slightly higher than the sea at the same latitude, this little difference prolongs the ice sealing period of the bay, polar bears have more ice hunting time, coupled with the rich minerals and organic matter brought by the river, making the bay flounder, cod, salmon, as well as marine life such as walruses, seals, dolphins, orcas, beluga whales and other marine organisms. It also provides a large number of predatory opportunities for polar bears.
The rich minerals brought by the river's influx make the bay rich in flounder, cod and salmon, as well as marine life such as walruses, seals, orcas, and beluga whales.
Hudson Bay is considered an "internal water" by Canada and classified as a "closed sea area", and anyone who wants to enter this area must be approved by the relevant Canadian authorities.
Today, Hudson Bay is regarded by Canada as the country's "internal water" and classified as a "closed sea area", and anyone who wants to enter this area must obtain the approval of the relevant Canadian authorities. Because of this, the Hudson Bay area, which was already very densely populated, has become an Eden for many wild animals.
