Hudson Bay

A vast inland sea where gravity is slightly weaker than normal/Water

Hudson Bay is a large body of saltwater in northeastern Canada, the second-largest bay in the world after the Bay of Bengal. Covering approximately 1.23 million square kilometers (about 12% of Canada's total area), it is ice-covered for roughly 8 months of the year. The bay holds a gravitational anomaly: gravity in the region is measurably weaker than the global average, likely due to the lingering effects of the Laurentide Ice Sheet that depressed the land during the last ice age. The land is still rebounding at a rate of about 1 centimeter per year. Churchill, Manitoba, on its western shore, is known as the 'polar bear capital of the world.'
