WebQuestion: It is estimated that the ice sheet over Hudson Bay, Canada ha a thickness of 2 km. At the present time there is a negative free-air gravity anomaly in this region of 0.3 mm/s2. In other words, the gravity is 0.3 mm/s^2 less than expected at this distance from the center of the Earth. a. WebHudson Bay and the associated structural basin lies within the centre of a large free-air gravity anomaly that lies within the Canadian Shield. I’m looking into what you are saying and see as many as 6-9 larger impacts in Hudson bay with multiple small impacts which in all created Hudson bay. index online on or off
