Archaeological material obtained from Eskimos on the east side of Hudson Bay has been described by Mathiassen, Quimby, and Jenness, but no systematic excavations have been made in the area. Mathiassen was told by Mr. S. Berthfi of Reveillon Frdres that there were house ruins of turf and stone on the east coast of Hudson Bay at Kovik Bay, Mosquito Bay, and Cape Dufferin, and also on the Ottawa Islands; and by Mr. Perdy of the Hudson's Bay Company that there were house ruins at Cape Wolstenholme and many around Port Harrison. Obviously, Mathiassen concluded that these were regular houses of the Thule type. Quimby6 found only oval and rectangular tent rings on the Belcher Islands, and assumed that the semisubterranean houses characteristic of the Thule culture were lacking.

Concentration Levels

Background levels of petroleum residues in the form of particles floating on the sea and as substances extracted from the surface microlayer, the water column, and the surficial bottom sediments of the Hudson Strait/Foxe Basin and the Labrador shelf regions were measured during 1982 and 1983. No evidence of floating particulate oil was found in either region. Background levels of extractable petroleum residues in the surface microlayer were highly dependent on ambient sea conditions and ranged from 4.1 μg/L at the entrance to Hudson Strait to 28.3 μg/L on the southern Labrador shelf in 1982, and from 4.5 to 20.9 μg/L on the Labrador shelf in 1983 with the general background level at 8.13 μg/L. The background level in the water column in the Hudson Bay/Hudson Strait region was 0.46 μg/L in 1982 whereas that on the Labrador shelf was 0.42 μg/L during 1982 and 0.57 μg/L in 1983 (overall level of 0.51 μg/L). Concentration levels in the surficial bottom sediments depended primarily on the nature of the sediments and ranged from 1.9 μg/g at the eastern end of Hudson Strait to 52.5 μg/g on the continental slope east of Nain Bank with a general background level of 2.04 μg/g. These background levels are similar to those of other areas of the continental shelf off the east coast of Canada and are, presently, well below those known to have adverse biological consequences.

Long Term Variations

Two new dendrochronological series of eastern larch (Larixlaricina (Du Roi) K. Koch) from subarctic Quebec extend from 1710 to 1987 (Whapmagoostui–Kuujjuarapik, eastern Hudson Bay) and from 1596 to 1978 (Rivière aux Feuilles, western Ungava). In both regions, the tree-ring series show similar long-term variations. Generally, conditions were more favorable for growth at the end of the 19th century and during the 20th century than before. A comparison of several larch and white spruce (Piceaglauca (Moench) Voss) tree-ring series from northern Quebec indicates significant shared variance between regions and species. Larch chronologies show two important depressions during the 20th century, between 1905–1908 and 1940–1946, which are more obvious in the two series from the southern forest–tundra than in the series from Ungava. These may be caused by outbreaks of the larch sawfly, Pristiphoraerichsonii (Htg.).

The polar bear, Thalarctos maritimus, (Phipps) enjoys such colloquial names as: “ice-bear,” “sea-bear,” “ice-tiger” and “ice-king.” In view of its large size and its supremacy over the other beasts of the ice-floes it well deserves these epithets. Primarily the polar bear is an animal of the broken arctic pack ice and is found in greatest numbers along the southern edge of the pack. It avoids large expanses of open water or frozen sea ice. The movements of the pack ice to a large degree determine its distribution and movements. Polar bears are carried southward with the pack ice in the spring and summer. In August and September when the ice begins to break up they generally come ashore and make their way north. At this time of year they may be found in considerable numbers along certain coasts where the sea ice has been brought by the winds, tides and currents. An Eskimo from Southampton Island, in northern Hudson Bay, informed me that in August, 1948, he and a companion counted over 180 of these bears along the east coast of that island.

Major permafrost landforms of the discontinuous permafrost zone of Hudson Bay and James Bay, Quebec–Labrador Peninsula, are described and interpreted within an ecological perspective. These landforms are not fossil permafrost bodies; they are presently evolving under aggrading and degrading developmental stages. Permafrost peat complexes and permafrost mineral complexes are differentially distributed in the midtaiga, the forest–tundra, and the shrub–tundra zones of the study area. The wooded palsa complex is the most obvious permafrost complex in the midtaiga, and the palsa complex in the forest–tundra: The wooded palsa complex is related to the forest chronosequence, whereas the palsa complex, farther north, occurs where there is a suitable macroclimate for permafrost aggradation without the influence of cool forest microclimate. The wooded cryogenic mound complex in mineral landform is mainly distributed in the southern section of the forest–tundra and near the Hudson Bay shore; the cryogenic mineral mound complex is found in the northern section. The latitudinal shift of the northern complex is necessary for permafrost initiation in open sites. Degrading stages associated with thermokarst activity are similar for all these landforms and it is suggested that palsa complex is made of incipient, mature, and residual palsas whether they belong to palsa mounds or to peat plateaus. Similar conclusions are valid for cryogenic mineral mound complex.
