2018 Richardson Mountains
Principal Investigator: Hadlari, Thomas
Licenced Year(s): 2018
Summary: Some models for opening of the Arctic Ocean place Alaska against the Canadian Arctic Islands before Cretaceous time. Other models using orthogonal continental drift place the counterpart to the Canadian Arctic Islands in northern Russia. The two models predict very different structural dynamics at the potential hinge point of rotation and so the Richardson Mountains are a critical area for resolvi...


Synthesis of Glacial History and Dynamics in the Western Rae Geological Province
Principal Investigator: Campbell, Janet
Licenced Year(s): 2018
Summary: The overall goal of this activity is to compile and understand the history of ancient glaciations in mainland Northwest Territories and Nunavut. A field team of 3 people will undertake the work proposed. The field work will be based out of Aylmer Lake Lodge, Aylmer Lake, NWT with the entire crew returning to the lodge at the end of each field day. The field survey will be supported by one hel...


Glacier mass balance of the Melville South Ice Cap
Principal Investigator: Burgess, David O
Licenced Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: The objectives of this study are to estimate the amount of water equivalent mass the Melville South Ice Cap loses (or gains) on an annual basis, and to derive a long-term climate record from glacier measurements and weather station data in order to determine trends in climate change for this region of the NWT. Mass balance is measured at each of the ~21 poles across the ice cap as function of s...


Southern Mackenzie Surficial Mapping
Principal Investigator: Paulen, Roger C.
Licenced Year(s): 2018 2017
Summary: Activities in the study are focused on making a map of the surface sediments. The map will help to understand surface material distribution and thickness, how these materials were deposited by glaciers, and where the bedrock outcrops. Soil samples will be collected across the study area. The mineralogical and geochemical analyses of these samples will help to understand where the materials were de...


Glacial lakes McConnell and Mackenzie reconstructed from Pleistocene deltas of the Mackenzie River tributaries
Principal Investigator: Froese, Duane G
Licenced Year(s): 2017 2016
Summary: The objective of this project is to investigate the architecture of Pleistocene deltas on the Mackenzie River tributaries, search evidence of high-magnitude discharge events, and collect samples for absolute dating. The research team will investigate the stratigraphic description of sedimentary sections in the river banks cutting through the Pleistocene deltas. Collection of samples are for rad...


Glacial limits of western Northwest Territories
Principal Investigator: Duk-Rodkin, Alejandra ADR
Licenced Year(s): 2017
Summary: The objective of this research is to create a regional 1:1,000,000 scale glacial limits map with glacier extent of various ages, ice-flow indicators and drainage diversions. The map will cover the Northwest Territories south from 66° 00’ 00” N and east of the continental divide. Work is mainly conducted through visual examination, description, measurement, and photography of surficial features....


Holocene Glacier Fluctuations in Nahanni National Park Reserve, Northwest Territories, Canada
Principal Investigator: Menounos, Brian p
Licenced Year(s): 2017 2016
Summary: The objective of the study is to date the formation of terminal moraines fronting Brintnell Glacier, and analyze the glacigenic signature within the sediments of Glacier Lake in order to develop a robust chronology of glacier change on the Brintnell-Bologna Icefield. This decade to century scale chronology will be compared to regional-to-hemispheric climate proxies to evaluate the climate sensitiv...


Noell Lake Ice Study - Hydro-ecological Responses of Arctic Tundra Lakes to Climate Change and Landscape Perturbation
Principal Investigator: Wrona, Frederick J
Licenced Year(s): 2015 2014 2013 2012 2011 2010 2009
Summary: The overall objective of this research is to improve the knowledge on lake ice and its effect on food webs/productivity in small Arctic lake systems in order to better predict changes that could occur under changing climate. The research involves the automated ice buoy and instrumented subsurface mooring system for continuous monitoring of weather conditions, lake ice cover (formation, growth o...


University of Washington Marginal Ice Zone
Principal Investigator: Lee, Craig
Licenced Year(s): 2014
Summary: The objectives of this research project are to: continue observations of the Arctic Ocean environment; understand the physical environment and processes; and develop integrated air–ice–ocean–wave models for improved prediction. The University of Washington is conducting marine scientific research to study the Marginal Ice Zone (MIZ) in the Beaufort Sea approximately 200 nautical miles west of S...


Testing the northern route for Younger Dryas meltwater
Principal Investigator: Keigwin, Lloyd D
Licenced Year(s): 2013
Summary: Here is the project summary from the (U.S.) National Science Foundation proposal that led to this expedition: The research team propose a three-year project to investigate the origin of the Younger Dryas cooling that began about 13,000 years ago. For decades this cold event has been associated with sea ice in the Arctic and North Atlantic Oceans, and the storage and release of fresh water from ...
