Two major tholeiitic magmatic pulses characterize HALIP: an initial 120 -130 Ma pulse that affected Arctic Canada and formally adjacent regions of Svalbard (Norway) and Franz Josef Land (Russia). In Canada, this pulse fed lava flows of the Isachsen Formation. A second 90-100 Ma pulse that apparently only affected the Canadian side of the Arctic, fed flood basalts of the Strand Fiord Formation. The goal of this thesis is to improve understanding of Arctic magmatism of the enigmatic HALIP through field, remote sensing, geochemical and geochronology investigations of mafic intrusive rocks collected in the South Fiord area of Axel Heiberg Island, Nunavut, and comparison with mafic lavas of the Isachsen and Strand Fiord Formations collected from other localities on the Island. Ground-based and remote sensing observations of the South Fiord area reveal a complex network of mafic sills and mainly SSE-trending dykes. Two new U-Pb baddeleyite ages of 95.18 ± 0.35 Ma and 95.56 ± 0.24 Ma from South Fiord intrusions along with geochemical similarity confirm these intrusions (including the SSE-trending dykes) are feeders for the Strand Fiord Formation lavas.

    ARCTIC VOL. 48, NO.4 (DECEMBER 1995) P. 313–323 Wolf-Sightings on the Canadian Arctic Islands FRANK L. MILLER1 and FRANCES D. REINTJES1 (Received 6 April 1994; accepted in revised form 13 March 1995) ABSTRACT. A wolf-sighting questionnaire was sent to 201 arctic field researchers from many disciplines to solicit information on observations of wolves (Canis lupus spp.) made by field parties on Canadian Arctic Islands. Useable responses were obtained for 24 of the 25 years between 1967 and 1991. Respondents reported 373 observations, involving 1203 wolf-sightings. Of these, 688 wolves in 234 observations were judged to be different individuals; the remaining 515 wolf-sightings in 139 observations were believed to be repeated observations of 167 of those 688 wolves. The reported wolf-sightings were obtained from 1953 field-weeks spent on 18 of 36 Arctic Islands reported on: no wolves were seen on the other 18 islands during an additional 186 field-weeks. Airborne observers made 24% of all wolf-sightings, 266 wolves in 48 packs and 28 single wolves. Respondents reported seeing 572 different wolves in 118 separate packs and 116 single wolves. Pack sizes averaged 4.8 ± 0.28 SE and ranged from 2 to 15 wolves. Sixty-three wolf pups were seen in 16 packs, with a mean of 3.9 ± 2.24 SD and a range of 1–10 pups per pack. Most (81%) of the different wolves were seen on the Queen Elizabeth Islands. Respondents annually averaged 10.9 observations of wolves ·100 field-weeks-1 and saw on average 32.2 wolves·100 field-weeks-1· yr -1 between 1967 and 1991.

Mr. Ekblaw, who was placed in charge of the 1916 expeditin, will present a separate report. The results of the expedition, naturally, depended upon the loca tion of its headquarters. The enforced selection of Etah, North Green- land, seriously handicapped the work of the expedition from start to finish, while the. expenses of the party were more than doubled. The. first accident, the grounding of the Diana upon the coast of Labrador, was a regrettable adventure. The consequent delay, due to unloading, chartering, and reloading, resulted in such a late arrival at Etah that our plans were disarranged. It curtailed in many ways the eageimess of the men to reach their objective point at the head of Flagler Bay, te proposed site of the winter quarters. The leader and his party being but passengers upon a chartered ship was another handicap, since the captain emphatically declared that he would not steam across Smith Sound. There was but one decision to be made, namely: to land upon the North Greenland shore within striking distance of Cape Sabine.

Diatom assemblages changed markedly since the mid-19th century following relatively stable community composition that spanned centuries to millennia. Three different assemblages, primarily composed of Fragilaria pinnata, Diadesmis spp., or Pinnularia spp., dominated the pre-1850 period at the three sites, but were replaced with different, more diverse assemblages in recent sediments. These species shifts occurred in the mid- to late-19th century in the Isachsen sites, and in the mid- to late-20th century in our Alert site. This difference in timing appears to be a result of the different sensitivities of lakes and ponds to environmental change, rather than of site-specific chemical properties. Reconstructions of pH using diatom inference models indicated increases from 0.5 to 0.8 pH units at these sites over this period of assemblage change. The diatom-inferred pH record from Alert showed agreement with measured climate data from Alert over the last 30 years.

    Using GPS Mapping Software to Plot Place Names and Trails in Igloolik (Nunavut) CLAUDIO APORTA1

    ARCTIC VOL. 56, NO. 4 (DECEMBER 2003) P. 321–327 New Ways of Mapping: Using GPS Mapping Software to Plot Place Names and Trails in Igloolik (Nunavut) CLAUDIO APORTA1 (Received 11 July 2001; accepted in revised form 10 February 2003) ABSTRACT. The combined use of a GPS receiver and mapping software proved to be a straightforward, flexible, and inexpensive way of mapping and displaying (in digital or paper format) 400 place names and 37 trails used by Inuit of Igloolik, in the Eastern Canadian Arctic. The geographic coordinates of some of the places named had been collected in a previous toponymy project. Experienced hunters suggested the names of additional places, and these coordinates were added on location, using a GPS receiver. The database of place names thus created is now available to the community at the Igloolik Research Centre. The trails (most of them traditional, well-traveled routes used in Igloolik for generations) were mainly mapped while traveling, using the track function of a portable GPS unit. Other trails were drawn by experienced hunters, either on paper maps or electronically using Fugawi mapping software. The methods employed in this project are easy to use, making them helpful to local communities involved in toponymy and other mapping projects. The geographic data obtained with this method can be exported easily into text files for use with GIS software if further manipulation and analysis of the data are required.

The history of the explordtion of the Central Arctic Ocean is reviewed.It has been only within the last 15 years that any signifi- cant number of depth-sounding data have been collected.The present study uses seven million echo soundings collected by U. S. Navy nuclear submarines along nearly 40, 000 km of track to construct, for the first time, a reasonably complete picture of the physiography of the basin of the Arctic Ocean.The use of nuclear submarines as under-ice survey ships is discussed. The physiography of the entire Arctic basin and of each of the major features in the basin are described, illustrated and named. The dominant ocean floor features are three mountain ranges, generally paralleling each other and the 40°E. 140°W. meridian. From the Pacific- side of the Arctic basin toward the Atlantic, they are: The Alpha Cordillera; The Lomonosov Ridge; andThe Nansen Cordillera. The Alpha Cordillera is the widest of the three mountain ranges. It abuts the continental slopes off the Canadian Archipelago and off Asia across more than550of longitude on each slope.Its minimum width of about 300 km is located midway between North America and Asia.In cross section, the Alpha Cordillera is a broad arch rising about two km, above the floor of the basin.The arch is marked by volcanoes and regions of "high fractured plateau, and by scarps500to 1000 meters high.The small number of data from seismology, heat flow, magnetics and gravity studies are reviewed.The Alpha Cordillera is interpreted to be an inactive mid-ocean ridge which has undergone some subsidence.

    Movements and Habitat Use of Muskoxen on Bathurst, Cornwallis

    MOVEMENTS AND HABITAT USE OF MUSKOXEN (Ovibos moschatus) ON BATHURST, CORNWALLIS, AND DEVON ISLANDS, 2003-2006 Morgan Anderson1 and Michael A. D. Ferguson Version: 23 December 2016 1Department of Environment, Government of Nunavut, Box 209 Igloolik NU X0A 0L0 STATUS REPORT 2016-08 NUNAVUT DEPARTMENT OF ENVIRONMENT WILDLIFE RESEARCH SECTION IGLOOLIK, NU i Summary Eleven muskoxen (Ovibos moschatus) were fitted with satellite collars in summer 2003 to investigate habitat preferences and movement parameters in areas where they are sympatric with Peary caribou on Bathurst, Cornwallis, and Devon islands. Collars collected locations every 4 days until May 2006, with 4 muskoxen on Bathurst Island collared, 2 muskoxen collared on Cornwallis Island, and 5 muskoxen collared on western Devon Island. Only 5-29% of the satellite locations were associated with an estimated error of less than 150 m (Argos Class 3 locations). Muskoxen in this study used low-lying valleys and coastal areas with abundant vegetation on all 3 islands, in agreement with previous studies in other areas and Inuit qaujimajatuqangit. They often selected tussock graminoid tundra, moist/dry non-tussock graminoid/dwarf shrub tundra, wet sedge, and sparsely vegetated till/colluvium sites. Minimum convex polygon home ranges representing 100% of the locations with <150 m error include these movements between core areas, and ranged from 233 km2 to 2494 km2 for all collared muskoxen over the 3 years, but these home ranges include large areas of unused habitat separating discrete patches of good habitat where most locations were clustered. Several home ranges overlapped, which is not surprising, since muskoxen are not territorial.
