The climate here is strongly influenced by the cold Hudson Bay low-pressured and polar high-pressure air masses. The climate depends largely on the water surface during certain parts of the year. In the winter months the bay is covered almost entirely by pack ice and this keeps the air chilled and thus temperatures stay consistently low. [ 16 ]
The geographic poles are defined by the points on the surface of Earth that are intersected by the axis of rotation. The pole shift hypothesis describes a change in location of these poles with respect to the underlying surface – a phenomenon distinct from the changes in axial orientation with respect to the plane of the ecliptic that are caused by precession and nutation, and is an ...
Hudson Bay, [a] 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 is located north of Ontario , west of Quebec , northeast of Manitoba , and southeast of Nunavut , but politically entirely part of Nunavut. [ 5 ]
The Nunavik component of this global project was initially oriented towards the investigation of Thule/Inuit archaeology in Hudson Bay and Hudson Strait, within a context of climatic change. [1] The Qijurittuq site research is directed at change in semi-subterranean dwellings and whether it was due to climate change, technology, and/or ...
The effects of climate change are most profound in the southern part of the polar bear's range, and this is indeed where significant degradation of local populations has been observed. [11] The Western Hudson Bay subpopulation, in a southern part of the range, also happens to be one of the best-studied polar bear subpopulations.
Later ice formation, and earlier ice breakup outside the dike corresponding to an opposite change in the fresh waters inside; Diminished ecological productivity, possibly as far away as the Labrador Sea; Fewer nutrients being deposited into Hudson Bay during spring melts; Removal of James Bay's dampening effect on tidal and wind disturbances; and
Predictably, given its northern latitude, Whapmagoostui has a subarctic climate (Dfc) under the Köppen climate classification, but strongly modified by its location on the southeastern (predominantly windward) shore of Hudson Bay, particularly from May/June through November, the primary season when Hudson Bay's surface is unfrozen, i.e. open water.
One of the final general conclusions made by Hoover et al. stated that while many current harvested populations will decrease with proposed climate change, ringed seals should be considered for redirecting harvest towards their populations. In the Hudson Bay, Canada, the body conditions of ringed seals were observed from 2003-2013.
