A new feature introduced in this edition is a section containing four essays: The HUDSON 70 Expedition by C.R. Mann Earth Sciences Studies in Arctic Marine Waters, 1970 by B.R. Pelletier Analysis of Marine Ecosystems by K.H. Mann Operation Oil by C.S. Mason and Wm. L. Ford They serve as an overview of the focal interests of the past two years in contrast to the body of the Review, which is basically a series of individual progress reports. The search for petroleum on the continental shelves of Eastern Canada and Arctic intensified considerably with several drilling rigs and many geophysical exploration teams in the field. To provide a regional depository for the mandatory core samples required from all drilling, the first stage of a core storage and archival laboratory was completed in 1970. This new addition to the Institute is operated by the Resource Administration Division of the Department of Energy, Mines & Resources. In a related move the Geological Survey of Canada undertook to establish at the Institute a new team whose primary function will be the stratigraphic mapping of the continental shelf. -
Circulation of Surface Waters in Parts of the Canadian Arctic Archipelago Based on Foraminiferal Evidence'
Circulation of Surface Waters in Parts of the Canadian Arctic Archipelago Based on Foraminiferal Evidence' G. VILKS2 ABSTRACT. Planktonic foraminifera are present both in bottom sediments and surface waters on theshelf area averaging 400 metres in depth to the west of a line between Cape MClure and Cape Meecham, but in M'Clure Strait proper to the east of this line in the surface waters only. The evidence is used to suggest a slow net eastward movement of water from the ocean through MClure Strait in the past with increased ratesat the present time. RÉSUMÉ. La circulation des eaux de surface dans certaines parties de l'archipel arctique canadien, d'après l'étude des foraminifères. Dans la zone du plateau, d'une profondeur moyenne de 400 mètres, à l'Ouestd'une ligne tirée entre le cap de MClure et le cap de Meecham, les foraminifères planctoniques sont présents B la fois dans les sédiments du fond et dans les eaux de surface; mais à l'Est de cette ligne, dans le détroit de M'Clure proprement dit, on ne les trouve que dans les eaux de surface. Cet indice suggère, pour lepassé, un mouvement net des eaux de l'océan vers l'Est, B travers le détroit de MClure, avec des taux accrus dans le présent. PE3IOME.

Deglaciation of the Laurentide Ice Sheet from the Last Glacial Maximum
Cuadernos de Investigación Geográfica ISSN 0211-6820 2017 Nº 43 (2) pp. 377-428 Geographical Research Letters eISSN 1697-9540 DOI: http://doi.org/10.18172/cig.3237 © Universidad de La Rioja DEGLACIATION OF THE LAURENTIDE ICE SHEET FROM THE LAST GLACIAL MAXIMUM C.R. STOKES* Department of Geography, Durham University, Durham, DH1 3LE, UK ABSTRACT. The last deglaciation of the Laurentide Ice Sheet (LIS) was associated with major reorganisations in the ocean-climate system and its retreat also represents a valuable analogue for understanding the rates and mechanisms of ice sheet collapse. This paper reviews the characteristics of the LIS at its Last Glacial Maximum (LGM) and its subsequent deglaciation, with particular emphasis on the pattern and timing of ice margin recession and the driving mechanisms of retreat. The LIS initiated over the eastern Canadian Arctic ~116-110 ka (MIS 5d), but its growth towards the LGM was highly non-linear and punctuated by several episodes of expansion (~65 ka: MIS 4) and retreat (~50-40 ka: MIS 3). It attained its maximum position around 26-25 ka (MIS 2) and existed for several thousand years as an extensive ice sheet with major domes over Keewatin, Foxe Basin and northern Quebec/Labrador. It extended to the edge of the continental shelf at its marine margins and likely stored a sea-level equivalent of around 50 m and with a maximum ice surface ~3000 m above present sea-level. Retreat from its maximum was triggered by an increase in boreal summer insolation, but areal shrinkage was initially slow and the net surface mass balance was positive, indicating that ice streams likely played an important role in reducing the ice sheet volume, if not its extent, via calving at marine margins. -

The Use of Dog Sledges During the British Search for the Missing Franklin Expedition in the North American Arctic Islands, 1848–59 WILLIAM BARR1
ARCTIC VOL. 62, NO. 3 (SEPTEMBER 2009) P. 257–272 The Use of Dog Sledges during the British Search for the Missing Franklin Expedition in the North American Arctic Islands, 1848–59 WILLIAM BARR1 (Received 4 September 2008; accepted in revised form 17 October 2008) ABSTRACT. While the bulk of the searching parties sent out from the British ships deployed on the search for the missing Franklin expedition in the North American Arctic Islands over the period 1848–59 employed man-hauled sledges, dog sledges were also used quite extensively. The dog sledges were especially (but not exclusively) used as “couriers,” that is, for communi- cation between the various wintering ships, where speed was the primary requirement. The total distance covered by dog sledges (excluding short hauls in the vicinity of the wintering ships) was, at a minimum, 11 576 km; this distance compares with the minimum 41 555 km covered by man-hauled sledges. Key words: dog sledges, Franklin search expeditions, North American Arctic Islands RÉSUMÉ. Bien que la plupart des équipes de recherche déployées par les navires britanniques à la recherche de l’expédition de Franklin disparue dans l’archipel Arctique nord-américain pendant la période de 1848–1859 se soient servi de traîneaux tirés par des humains, elles ont également employé des traîneaux à chiens à maintes reprises. Les traîneaux à chiens servaient plus particulièrement (mais non pas exclusivement) de « messagers » en ce sens qu’ils établissaient les liens de communication entre les divers navires en hivernage, la rapidité de transmission étant essentielle. La distance totale à avoir été parcourue par les traîneaux à chiens (ce qui ne comprend pas les courtes distances dans la région des navires en hivernage) s’est chiffrée, au minimum, à 11 576 kilomètres, comparativement à la distance minimale de 41 555 kilomètres parcourue par les traîneaux tirés par des humains.
