  • Compendium of Research in the Northwest Territories 2014
    Compendium of Research in the Northwest Territories 2014 www.nwtresearch.com This publication is a collaboration between the Aurora Research Institute, the Department of Environment and Natural Resources, Fisheries and Oceans Canada and the Prince of Wales Northern Heritage Centre. Thank you to all who submitted a summary of research or photographs, and helped make this publication possible. Editor: Ashley Mercer Copyright © 2015 ISSN: 1205-3910 Printed by Aurora Research Institute Foreword Welcome to the 2014 Compendium of Research in the Northwest Territories. This year marked a special anniversary for the Aurora Research Institute and northern research. Fifty years ago, the Inuvik Research Laboratory was built and has served as a hub for research in the western arctic ever since. The Lab, as it was known, was first built as an initiative of the Canadian federal government in the newly established community of Inuvik. It remains on the same site today, but in 2011, a new modern multi-purpose facility opened to continue to support research in the north. We have included a brief history of the Lab and its impact in this edition of the Compendium to mark its long lasting importance to many researchers and community members. As part of the 50th anniversary celebration, the Aurora Research Institute team undertook a full set of NWT-wide celebrations. We celebrated the history, capacity and growth of research in the NWT that touched all corners of the territory and beyond. We honoured the significant scientific contributions that have taken place in the NWT over the past 50 years, and the role of NWT researchers, technicians and citizens in these accomplishments.

  • Represent 25 Species
    59.9(71.2) Article II.- MAMMALS FROM THE ATHABASKA-MIACKENZIE REGION OF CANADA. By J. A. ALLEN. During the summer of 1907 Mr. E. Thompson Seton, accompanied by Mr. Edward A. Preble of the Biological Survey as assistant, made an expedi- tion to the Barren Grounds in the vicinity of Aylmer Lake, Mackenzie District, for the purpose of natural history exploration. Their route was by way of the Athabaska River, Slave River, Great Slave Lake, and the chain of lakes northeastward to Aylmer Lake. The birds and mammals obtained on this trip were purchased for this Museum, through the generosity of Mrs. Morris K. Jesup. The birds have already been briefly reported upon by Mr. Seton; ' for the sake of the localities, and the measurements taken by Mr. Preble from the specimens in the flesh, it seems worth while to record these data for the mammals, which comprise about 2-70 specimens, and represent 25 species. The principal points at which collections were made are: Athabaska River, 20 miles below Athabaska Landing, May 18 and 19; Grand Rapids, Athabaska River, May 22-24; Fort McMurray, Athabaska River, May 28, 29; Slave River, June 6-8; Fort Smith, Slave River, on the Athabaska- Mackenzie boundary, June 13-July 2; Great Slave Lake (various points), July 19-27, September 10-27; east shore of Artillery Lake, August 2-5; Aylmner Lake (various points), August 14-29; Artillery Lake (mostly east shore at tree limit), August 31-September 8. The collection consists mainly of rodents, but lacks representatives of the genera Phenacomys and Synaptomys; it also contains only a single specimen of Sorex, and single specimens each of three species of Putorius; also only two specimens of Lepus, and one of Eutamias.

  • 2018 Yellowknife Geoscience Forum Abstract and Summary Volume
    2018 Abstract and Summary Volume Cover photograph Carcajou River, NWT; Viktor Terlaky, Senior Petroleum Geologist at the Northwest Territories Geological Survey The picture was taken following a rainstorm along Carcajou River, NWT, which resulted in a spectacular rainbow across the river valley. In the background are outcrops of the Late Devonian Imperial Formation, interpreted to be submarine turbidite deposits. The light bands are sandstone bodies intercalated with the darker shale intervals, representing periodic activity in sedimentation. Compiled by D. Irwin, S.D. Gervais, and V.

  • Movements and Distribution of the Bathurst and Ahiak Barren-Ground
    Movements and distribution of the Bathurst and Ahiak barren-ground caribou herds 2005 Annual Report Submitted to West Kitikmeot Slave Study Society Submitted By Project Leader Anne Gunn Project Team Adrian D’Hont, Judy Williams Organisation Wildlife Division, Environment and Natural Resources, Government of the Northwest Territories, Yellowknife. 2 Summary: Objectives for 2005 included deploying 10 collars on cows from the Bathurst caribou herd and 10 collars on cows from the Ahiak caribou herd. A reconnaissance survey over the winter range of the Bathurst herd found heavy concentrations of caribou at Lac Grandin southeast to Rae Lakes and then low densities of caribou until east of Yellowknife. Of the 10 collars put on the Bathurst range, three died between April and June and the remaining seven calved on the Bathurst calving ground. Flights over the Ahiak winter range resulted in no caribou seen east of Contwoyto, low concentrations on the Back River and high concentrations east of Artillery Lake and in the Nonacho Lake area. Five collars were deployed east of Artillery Lake and five in the Nonacho Lake area. Of the five collars deployed in the Nonacho Lake area, two caribou migrated to the Bathurst calving ground. The remaining eight collars calved on the Ahiak calving ground. In 2005, in addition to addressing the objectives of the movement and distribution study for individual herds we successfully collared 12 cows from the Bathurst herd and 8 from the Ahiak herd. We also documented overlap in the winter distribution of Ahiak and Bathurst caribou at Nonacho Lake. Acknowledgements: West Kitikmeot Slave Study Society funded the study and we thank the Board for their continued support.

Evenchick5 Received 13 May 2002; revised 9 April 2003; accepted 1 August 2003; published 30 March 2004. [1] The Cordillera in northern Canada is underlain deep layering on both profiles (300 km apart). The by westward tapering layers that can be followed base of the layered reflection zone coincides with from outcrops of Proterozoic strata in the Foreland the Moho, which exhibits variable character and belt to the lowermost crust of the orogenic interior, undulates in a series of broad arches with widths of a distance of as much as 500 km across strike. They 150 km. In general, the mantle appears to have are interpreted as stratified Proterozoic rocks, few reflections. However, at the southwest end of including 1.8–0.7 Ga supracrustal rocks and their Line 3 near the Alaska-British Columbia border, a basement. The layering was discovered on two new reflection dips eastward from 14.0 s to 21.0 s deep seismic reflection profiles in the Yukon (Line 3; (45 to 73 km depth) beneath exposed Eocene 650 km) and northern British Columbia (Line 2; magmatic rocks. It is interpreted as a relict 1245 km in two segments) that were acquired as subduction surface of the Kula plate.
