The polar bear : a matter for international concern   /   Flyger, V.
Arctic, v. 20, no. 3, Sept. 1967, p. 146-153, ill.
ASTIS record 10013
PDF

Discusses the decline in polar bear population, in part associated with recession of the polar ice cap, but also with excessive hunting. Annual worldwide harvest (ca 1200 reported) is about 5-10% of the population. An international commission is needed to coordinate study of population dynamics and movement patterns of these bears, and to regulate harvesting in the polar seas.


An ecological study of mobility and settlement patterns among the Belcher Island Eskimo   /   Freeman, M.M.R.

Settlement composition of these islands is based on co-residence of male siblings after marriage; seasonal or annual changes are mainly a result of economic pressures. Location and mobility of settlements is controlled by availability of food, dog-food, and fuel (driftwood, lichens). Acculturated groups migrate in winter to the west where foxes are abundant, in summer to the east for wage employment. Seasonal location of traditional settlements conforms to biogeographical features, viz: coastal characteristics which influence the number and availability of seals.

Étude écologique de la mobilité et du dessin des établissements chez les Esquimaux des îles de Belcher. Dans les îles de Belcher, un complexe de facteurs écologiques favorise le développement de techniques individuelles de production; c'est pourquoi la formation des établissements humains ne résulte pas des nécessités d'une activité économique collective. Les facteurs économiques sont les principaux responsables des changements dans la composition et la localisation des établissements, bien qu'en certaines saisons, les pressions sociales aient aussi une forte influence. La composition des établissements est largement basée sur la parenté, bien que des facteurs de la personnalité jouent aussi un rôle important. L'acculturation a une influence tant sur la mobilité que sur le dessin des établissements.

Twenty-one C14 dates of material from Late Quaternary marine terraces are used to construct an isostatic uplift curve. The phase of rapid uplift averaged about 26 ft. per 100 years, while for the past 5,200 years uplift was just under 1 ft. per 100 years. Updoming resulted in an upward (southerly) tilt of the "Glacier Beach" (460-ft. strandline) and "Upper Tunit Beach" (100-ft. strandline) at about 5.6 ft. per mile and 3.6 ft. per mile respectively. The C14 dates indicate that the general deglaciation of northern Ungava occurred about 7,000 to 8,000 years ago. Twelve well-formed marine terraces have been identified at the heads of the major fjords. The fauna of the "Upper and Lower Aporrhais Beaches" (40 ft. and 55 ft. strandlines) suggests that optimal marine conditions occurred about 3,900 to 5,230 radiocarbon years ago during a possible marine transgression. Hydroclimatic conditions during the formation of Aporrhais deposits in Sugluk Inlet (62°10'N.) corresponded to those at 58°15'N.

Relèvement du sol au Quaternaire récent dans le nord de l'Ungava, Québec. Pour construire une courbe de relèvement isostatique, l'auteur utilise 21 datations au C14 se rapportant à des terrasses marines. Le relèvement, dans sa phase la plus rapide, atteignit en moyenne 26 pieds (7,93 m) par siècle; cependant au cours des 5,200 dernières années, il s'est situé juste au-dessous d'un pied (30 cm) par siècle. Le bombement a provoqué un pendage vers le sud de la "plage Glacier" (plage soulevée à 460 pieds - 140,3 m) et de la "plage Tunit supérieure" (plage soulevée à 100 pieds - 30,5 m) d'environ 5,6 pieds au mille (1 m/km) et 3,6 pieds au mille (60 cm/km) respectivement. Les radio-datations indiquent que la déglaciation générale du nord de l'Ungava se produisit il y a environ sept à huit millénaires. A la tête des grands fjords, on a identifié douze terrasses marines bien développées. La faune des "plages Aporrhais supérieure et inférieure" (plages soulevées à 40 pieds -12,20 m - et à 55 pieds - 16,76 m) suggère que les conditions marines optimales se sont produites il y a environ de 3,900 à 5,230 ans, probablement au cours d'une transgression marine. Les conditions hydroclimatiques qui prévalaient lors de l'accumulation des dépôts "Aporrhais" du fjord de Sugluk (62°10'N) correspondaient à celles des dépôts situés au 58°15'N.

Reports recovery of nine records during geological reconnaissance by the Danish party of Operation Grant Land 1966, organized by the Geological Survey of Canada. The oldest is an 1876 copy of a record from 1871, the youngest dates from 1921. Records and relics from the US North Polar Expedition, 1871-73, British Arctic Expedition, 1875-76, US Lady Franklin Bay Expedition, 1881-84, Danish 2nd Thule Expedition, 1916-18, and Danish Bicentenary Jubilee Expedition, 1920-23, are included.

Documents et historiques de la côte nord du Groënland. L'auteur rapporte la découverte récente, sur la côte peu fréquentée du nord du Groënland, de neuf documents historiques et de vestiges qui leur sont associés. Le matériel provient de cinq expéditions arctiques de la fin du 19e siècle et du début du 20e, dans la région du chenal de Robeson. On a reproduit en facsimilé des pages de deux de ces documents.


The disturbance of arctic lake sediments by "bottom ice" : a hazard for palynology   /   Nichols, H.

A small unnamed lake, 100 m long and 3 m deep, about 15 km north of Pelly Lake, Keewatin District was largely frozen on Jun 15, 1966. Surface ice had melted by Jul 1, but water temp remained near freezing due to ice on the lake bottom. Blocks of bottom ice, which subsequently floated to the surface, were filled with sand and mud; these sediments were released as ice blocks floated and melted. It is suggested that the origin of "mud-center" lakes may be explained by such a process. Massive mixing of bottom sediments in shallow arctic and subarctic lakes, in Recent time and even under Pleistocene and late-glacial conditions is probable. Stratigraphic disturbance of lacustrine deposits, which will render them useless for palynologic research, would occur.
