Hudson Bay

Named for the Dutch explorer Henry Hudson who explored these waters in 1610, it is the second-largest bay on the planet, next to the Bay of Bengal.

Shallow, with an average depth near 100 m (333 ft), the bay is approximately 1,370 km (850 mi) long and 1,050 km (650 mi) wide.

In the northeast it connects to the Atlantic Ocean through the Hudson Strait, and in the north, it connects with the Arctic Ocean through the Foxe Basin.

There are scattered islands in Hudson Bay, mostly in the southeast, and also in James Bay, a smaller part of the larger bay. The islands within James Bay, as well as the Belcher Islands in Hudson Bay, are all considered a part of Canada's Nunavut Territory.

Literally hundreds of rivers (many small) flow into the bay. Some of the largest include the Albany, Eastmain, Grande, Severn and Winisk.
