According to Robert Frost's answer to Why is that Hudson Bay area of Canada has 4% less gravity than the rest of the world? The Nastapoka arc is a distinctively arcuate segment of the coastline of the southeastern shore of Hudson Bay, Canada, that extends from the most northerly of the Hopewell Islands to Long Island near the junction with James Bay.It is a prominent, near-perfect circular arc, covering more than 160° of a 450-km-diameter circle. The collection and interpretation of outcrop, seismic and drillhole data for exploration for oil and gas reservoirs within the Hudson Bay basin found that it is filled by, at most, 2,500 m (8,200 ft) of Ordovician to Devonian limestone, dolomites, evaporites, black shales, and various clastic sedimentary rocks that overlie less than 60 m (200 ft) of Cambrian strata that consist of unfossiliferous quartz sandsto… There are many islands in Hudson Bay, mostly near the eastern coast. At the extreme southern tip of the extension known as James Bay arises a humid continental climate with a longer and generally hotter summer. The Western Churchill and Superior cratons collided at about 1.9–1.8 Ga in the Trans-Hudson orogeny. The only Arctic deep-water port in Canada is the Port of Churchill, located at Churchill, Manitoba. Two main historic sites along the coast were York Factory and Prince of Wales Fort. It was incorporated in England on May 2, 1670, to seek a northwest passage to the Pacific, to occupy the lands adjacent to Hudson Bay, and to carry on commerce with those lands. This claim is disputed by the United States but no action to resolve it has been taken. Communities along the Hudson Bay coast or on islands in the bay are (all populations are as of 2016): The Hudson's Bay Company built forts as fur trade strongholds against the French or other possible invaders. [43][44] However, other Earth scientists have proposed that the evidence of an Archean impact might have been masked by deformation accompanying the later formation of the Trans-Hudson orogen and regard an impact origin as a plausible possibility. [17]:427 Starting in 1913, the Bay was extensively charted by the Canadian Government's CSS Acadia to develop it for navigation. Earth-Science Reviews 35, 4, p. 331–365.

Modeling glacial isostatic adjustment using the GRACE data, they concluded that ~25 to ~45% of the observed free-air gravity anomaly was due to ongoing glacial isostatic adjustment, and the remainder likely represents longer time-scale effects of mantle convection. Other authorities include it in the Atlantic, in part because of its greater water budget connection with that ocean. Some references of geological/impact structure interest include: Rondot, Jehan (1994). [19] This mapping progress led to the establishment of Churchill, Manitoba as a deep-sea port for wheat exports in 1929, after unsuccessful attempts at Port Nelson. Adjacent to the Nastapoka arc, these strata form a homocline that dips gently westward and consist of unmetamorphosed to slightly metamorphosed sandstone, stromatolite-bearing dolomite, banded iron formation, and basalt. [3][4], The portion of Hudson Bay immediately offshore of and partially encircled by the Nastapoka arc is underlain by Early Proterozoic strata of the Nastapoka Group. Hudson Bay occupies a large structural basin, known as the Hudson Bay basin, that lies within the Canadian Shield. The area is rocky and hilly. In the same volume, John Tuzo Wilson[47] commented on Beals' interpretation and alternately proposed that the Nastapoka arc may have formed as part of an extensive Precambrian continental collisional orogen, linked to the closure of an ancient ocean basin. However, other Earth scientists[11][12] have proposed that the preexisting structure of an older Archean impact structure might have been reactivated during and modified by the Trans-Hudson orogeny to form the Nastapoka arc. When Earth's gravitational field was mapped starting in the 1960s a large region of below-average gravity was detected in the Hudson Bay region. Author has 1.8K answers and 6.4M answer views. [13], The search for a western route to Cathay and the Indies, which had been actively pursued since the days of Columbus and the Cabots, in the latter part of the fifteenth century, directly resulted in the discovery of Hudson Bay. Hudson Bay (Inuktitut: Kangiqsualuk ilua, French: baie d'Hudson) (sometimes called Hudson's Bay, usually historically) is a large body of saltwater in northeastern Canada with a surface area of 1,230,000 km2 (470,000 sq mi). It is the only port of its size and scope in Canada that does not connect directly to the country's road system; all goods shipped overland to and from the port must travel by rail. It generated an emergent arch, on which reefs grew, that divided the basin into eastern and western sub-basins. We would expect Hudson bay to be at the higher end of gravitation. Further west, exposed in the Ottawa and Belcher Islands, the strata of the Nastapoka Group become highly faulted and tightly, often isoclinally, folded. No one knows the fate of Hudson or the crew members stranded with him, but historians see no evidence that they survived for long afterward. The current general consensus is that it is an arcuate boundary of tectonic origin between the Belcher Fold Belt and undeformed basement of the Superior Craton created during the Trans-Hudson orogeny. That means, if you weigh 150 pounds in a location with “average” gravity, you would weigh 149.9925 pounds in Hudson Bay. The collection and interpretation of outcrop, seismic and drillhole data for exploration for oil and gas reservoirs within the Hudson Bay basin found that it is filled by, at most, 2,500 m (8,200 ft) of Ordovician to Devonian limestone, dolomites, evaporites, black shales, and various clastic sedimentary rocks that overlie less than 60 m (200 ft) of Cambrian strata that consist of unfossiliferous quartz sandstones and conglomerates, overlain by sandy and stromatolitic dolomites. There is clear evidence that it is the arcuate edge of the Belcher fold-thrust belt, which was created 1.85-1.80 Ga ago. It is well away from the poles and it is at Sea Level. Hudson Bay (Inuktitut: Kangiqsualuk ilua, French: baie d'Hudson) (sometimes called Hudson's Bay, usually historically) is a large body of saltwater in northeastern Canada with a surface area of 1,230,000 km 2 (470,000 sq mi). It’s a result of mass, which means the varying density of the …
