Slave Province Surficial Materials and Permafrost Study
Principal Investigator: Elliott, Barrett R
Licenced Year(s): 2017 2015
Summary: The Northwest Territories Geoscience Office in the Department of Industry, Tourism and Investment (ITI) has developed a large collaborative research project to determine the detailed glacial history and permafrost conditions of the central Slave Geological Province. The project goals are to: - stimulate the next round of diamond and metals exploration in the Slave Province - collect permafr...


Heavy mineral indicator tracing in glaciated terrains
Principal Investigator: Kjarsgaard, Bruce
Licenced Year(s): 2012 2011
Summary: The objective of this study is to improve understanding of transportation and deposition of heavy minerals in surficial materials (till and esker systems). The study area is approximately 60 x 100 km, is located east of Thaydene Nene National Park, and adjacent to the Quaternary ice divide. Work on the ground, over a 2 week period, will involve sample collection of surficial materials in order...


Secular Change in the Glacier Cover Contributing Flow to a World Heritage River - Ragged Ranges, South Nahanni River
Principal Investigator: Demuth, Michael N
Licenced Year(s): 2007
Summary: The objectives of this research are to document the glaciers in the Ragged Range, how they have changed in the past and what their role is presently in providing meltwater for the upper reaches of the South Nahanni River and the Flat River. Glaciers nourish streams and groundwater when other sources are absent or in decline (e.g., snowmelt, precipitation). They are most important late in the...


Surficial mapping southern Mackenzie Valley
Principal Investigator: Duk-Rodkin, Alejandra ADR
Licenced Year(s): 2007 2006 2005 2004
Summary: This project involves surficial geology mapping of unmapped areas of NTS 95 G, H, and I, (61ºN to 63ºN and 120ºW to 124ºW) to assess granular resources, slope instability (landslide occurrence and potential) due to instability of the active layer, forest fires, erosion, and other factors, and regional geochemical analysis of till and gravel samples. The GSC will be working to improve our under...


Glacial History of the Great Slave Lake - Part 2: Surveys in Christie and McLeod Bays
Principal Investigator: Christoffersen, Poul
Licenced Year(s): 2006 2005
Summary: This project aims to reconstruct the glacial history of Great Slave Lake, focusing on deep troughs located in the northeast arm of the lake. A large ice dome formed over the Great Slave region during the Last Glacial Maximum and meltwater possibly formed a large subglacial lake in the deep sector of Christie Bay during this period, when ice was about 4 km thick. Subglacial lakes are important beca...


Glaciological Investigations in the Ragged Range
Principal Investigator: McCarthy, Daniel P
Licenced Year(s): 2006 2005
Summary: The objectives of this study are to: 1) inventory the size and morphometry of glaciers in the Ragged Range; 2) find and document geological and botanical evidence of former glacier activity; 3) develop a chronology for Holocene glacier activity in the Ragged Range; and, 4) develop one or more growth curves for lichens growing on carbonate and/or silicate rocks. Also, the field reconnaissance and b...


Environmental and Sea Level Change in the Northwestern Arctic Archipelago
Principal Investigator: England, John H
Licenced Year(s): 2012 2010 2009 2008 2007 2006 2005 2004 2003 2002
Summary: This research is concerned with the nature and style of past glaciations as well as the history of sea level and climatic changes in the western Arctic. The broad objective is to obtain a long term paleoclimatic record (before the arrival of the Pre-Dors...


The molecular population genetics of the arctic-alpine ground-beetle species Amara alpina
Principal Investigator: Schwert, Donald P.
Licenced Year(s): 1995 1992
Summary: The sample of arctic-alpine ground-beetles will be collected under rocks and by pitfall traps (dixie cups placed in 8 cm diameter drilled holes) in the tundra habitat. All rocks will be replaced exactly and pitfall trap holes refilled with their soil plugs. No chemicals will be used in any of the trapping or collecting. Specimens will be analysed using DNA techniques which include RLPF's and PC...


Late Quaternary Glacial and Climate History on Southern Baffin Island
Principal Investigator: Miller, Gifford H.
Licenced Year(s): 1994 1993 1991 1990 1989 1987
Summary: The researchers will obtain sediments from lakes near Cape Dyer to document past climatic conditions. Vegetation and lake water chemistry data will also be collected in order to collect information about the current environment: this data can be compared to historic data. Finally, the inner Frobisher Bay area will be surveyed for data about past sea levels and glacial landforms. This research w...


The application of Landsat imagery to map surficial deposits on Akpatok Island
Principal Investigator: LAURIOL, Bernard
Licenced Year(s): 1993
Summary: The researchers will map the types of rock and landforms of Akpatok Island using information collected from air photographs as well as data collected during the site visit. Samples of rock will be collected for further analysis. Interpretation of this information may provide clues as to the island's long-term history....
