MCGILL UNIVERSITY a STUDY on the SYNOPTIC Cllmatology MCGILL UNIVERSITY A STUDY ON THE SYNOPTIC CLlMATOLOGY OF BAFFIN ISLAND, NORTHWEST TERRITORIES by BLANE A. COULCHER A THESIS SUBMITTED TO THE FACULTY OF GRADUATE STUDIES AND RESEARCH IN PARTIAL FULFILMENT OF THE REQUIREMENTS FOR THE DEGREE OF MASTER OF SCIENCE DEPARTMENT OF GEOGRAPHY MONTREAL, QUEBEC September, 1967 ~ B1ane A. Cou1cher 1968 J .ABSTRACT The object of this paper is to describe and enlarge upon the clirnate of Baffin Island, N.W.T., and to relate these fea­ tures to the overall flow pattern across the areao A brief description of the Island and its observing network, including a short hi~torical summary, are outlined in Chapter I. Clirnatic controls are dealt with early in the study and sorne hitherto unpublished information on pressure distribution, cyclonic tracks, and the life cycle of disturbances rnigrating across the Island are provided. An atternpt is made to explain local weather peculiarities which frequently occur at noted stations by refer­ ring to particular examples showing characteristic synoptic situations and their effects. Finally, a general summary of the thesis is outlined in the conclusion. In aIl, the study attempts to embellish, colla te, and synthesize aIl climatic and synoptic parameters in order to present a more unified and coherent whole and thus contribute to a better understanding of meteorological processes affecting this remote and barren region. ii ACKNOWLEDGEMENTS l wish to express my many thanks to Prof. B. J. Garnier, the academic supervisor for this thesis. His valuable criticism and ideas were extremely helpful. My sincere appreciation goes to Mr. H. A. Thompson, Head of the Arctic Climatological Section in Toronto, and to his assistant, Mr. Don Veinot, for their valuable help and advice, and for providing additional reference material.

  • Transits of the Northwest Passage to End of the 2020 Navigation Season Atlantic Ocean ↔ Arctic Ocean ↔ Pacific Ocean
    TRANSITS OF THE NORTHWEST PASSAGE TO END OF THE 2020 NAVIGATION SEASON ATLANTIC OCEAN ↔ ARCTIC OCEAN ↔ PACIFIC OCEAN R. K. Headland and colleagues 7 April 2021 Scott Polar Research Institute, University of Cambridge, Lensfield Road, Cambridge, United Kingdom, CB2 1ER. <[email protected]> The earliest traverse of the Northwest Passage was completed in 1853 starting in the Pacific Ocean to reach the Atlantic Oceam, but used sledges over the sea ice of the central part of Parry Channel. Subsequently the following 319 complete maritime transits of the Northwest Passage have been made to the end of the 2020 navigation season, before winter began and the passage froze. These transits proceed to or from the Atlantic Ocean (Labrador Sea) in or out of the eastern approaches to the Canadian Arctic archipelago (Lancaster Sound or Foxe Basin) then the western approaches (McClure Strait or Amundsen Gulf), across the Beaufort Sea and Chukchi Sea of the Arctic Ocean, through the Bering Strait, from or to the Bering Sea of the Pacific Ocean. The Arctic Circle is crossed near the beginning and the end of all transits except those to or from the central or northern coast of west Greenland. The routes and directions are indicated. Details of submarine transits are not included because only two have been reported (1960 USS Sea Dragon, Capt. George Peabody Steele, westbound on route 1 and 1962 USS Skate, Capt. Joseph Lawrence Skoog, eastbound on route 1). Seven routes have been used for transits of the Northwest Passage with some minor variations (for example through Pond Inlet and Navy Board Inlet) and two composite courses in summers when ice was minimal (marked ‘cp’).

  • Hudson Bay Ice Conditions
    Hudson Bay Ice Conditions ERIC W. DANIELSON, JR.l ABSTRACT.Monthly mean ice cover distributions for Hudson Bay have been derived, based upon an analysis of nine years of aerial reconnaissance and other data. Information is presented in map form, along with diseussian Of significant features. Ice break-up is seen to work southward from the western, northern, and eastern edges of the Bay; the pattern seems to be a result of local topography, cur- rents, and persistent winds. Final melting occurs in August. Freeze-up commences in October, along the northwestern shore, and proceeds southeastward. The entire Bay is ice-covered by early January,except for persistent shore leads. RÉSUMÉ. Conditions de la glace dans la mer d’Hudson. A partir de l’analyse de neuf années de reconnaissances aériennes et d’autres données, on a pu déduire des moyennes mensuelles de distribution de la glace pour la mer d’Hudson. L‘informa- tion est présentte sous formes de cartes et de discussion des Cléments significatifs. On y voit que la débâcle progresse vers le sud à partir des marges ouest, nord et est dela mer; cette séquence sembleêtre le résultat de la topographielocale, des courants et .des vents dominants. La fonte se termine en aofit. L’enge€wommence en octobre le long de la rive nord-ouest et progresse vers le sud-est. Sauf pow les chenaux côtiers persistants, la mer est entihrement gelée au début de janvier. INTRODUCTION In many respects, ice cover is a basic hydrometeorological variable. In Hudson Bay (Fig. 1) it might be considered the most basic of all, as it influences all other conditions so decisively.

Phone: (306) 975-5357 Fax: (306) 975-4087, E-mail: [email protected] Summary: Mass-mortality events have been reported at several common eider breeding colonies in the Hudson Strait region of Nunavut and Nunavik. Laboratory testing has confirmed the presence of avian cholera, which is a disease affecting birds caused by infection with the bacterium Pasteurella multocida. Avian cholera does not cause serious illness in humans; however it is a major disease for waterfowl and its recent emergence in Nunavut poses a significant conservation concern. Working with multiple partners, we compiled information about past outbreaks and conducted coastal surveys to examine the geographic extent and severity of outbreaks in Nunavut during the summers of 2010, 2011 and 2012. We supplemented these data with information gathered at a long-term research station where common eiders have been studied since 1996, encompassing a period before, during and after a severe epidemic (Mitivik Island, East Bay Migratory Bird Sanctuary, Nunavut). Our results indicate that avian cholera is spreading within bird populations in the north and the presence of multiple serotypes of Pasteurella multocida, suggest that there have been multiple sources of introduction.

  • In Northern Foxe Basin, Nunavut
    Canadian Science Advisory Secretariat Central and Arctic Region Science Advisory Report 2014/024 ECOLOGICALLY AND BIOLOGICALLY SIGNIFICANT AREAS (EBSA) IN NORTHERN FOXE BASIN, NUNAVUT Figure 1. Northern Foxe Basin study area (red diagonal lines) with southern boundary line set at 68˚N. Context: During an arctic marine workshop held in 1994, Foxe Basin was identified as one of nine biological hotspots in the Canadian Arctic. In fall 2008 and winter 2009, the Oceans Program in Fisheries and Oceans Canada (DFO) Central and Arctic Region conducted meetings in Nunavut with the Regional Inuit Associations, Nunavut Tunngavik Inc., Nunavut Wildlife Management Board and Government of Nunavut to consider areas in Nunavut that might be considered for Marine Protected Area designation. The northern Foxe Basin study area, which includes Fury and Hecla Strait, was selected as one possible area (Figure 1). Based on a request for advice from Oceans Program, a science advisory meeting was held in June 2009 to assess the available scientific knowledge, and consider published local/traditional knowledge, to determine whether one or more locations or areas within the northern Foxe Basin study area would qualify as an Ecologically and Biologically Significant Area (EBSA). Two community meetings were subsequently held to incorporate local/traditional knowledge. This Science Advisory Report is from the June 29, 2009 (Winnipeg, MB), September 10, 2009 (Igloolik, NU) and November 19, 2009 (Hall Beach, NU) meetings for the Ecologically and Biologically Significant Areas selection process for northern Foxe Basin. Additional publications from this meeting will be posted on the DFO Science Advisory Schedule as they become available.
