Mapping for Ground Ice along the ITH
Principal Investigator: Alvarez, Alejandro
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No. 5791. The objectives of this study are to (1) evaluate the geologic setting including geochemistry, and dating of sediments to establish a regional history of the area. (2) investigate the geologic setting of multiple buried, massive ice bodies. And (3) develop a geologic and hazards map along the ITH, highlighting feature...


Watershed-scale geomorphic response to climate change in the Aklavik Range, NWT
Principal Investigator: Strauss, Justin Vincent
Licensed Year(s): 2024 2023 2022
Summary: This licence has been issued for the scientific research application No.5411. or this latest phase of research, the research team propose to integrate field observations, geochemical techniques, and historical remote sensing analysis to quantify the rates and processes by which sediment is generated from bedrock and transported downslope via hillslope and river processes under a changing climat...


Organic carbon cycle in the Mackenzie delta lakes
Principal Investigator: Lattaud, Julie
Licensed Year(s): 2022
Summary: This licence has been issued for the scientific research application No.5187. The project will study the dynamics of deltaic lake ecosystems over the past century through the application of recently developed molecular (lipid biomarker) and isotopic (radiocarbon and stable isotopes) proxies to lake sedimentary records. This will unravel the impact of old carbon input into aquatic ecosystems. Ra...


Nitrogen sources for Arctic freshwaters (NitroFresh)
Principal Investigator: Pastor, Ada
Licensed Year(s): 2021
Summary: This licence has been issued for the scientific research application No.5034. The main aim of Nitrofresh is to assess the nitrogen (N) sources for streams and the linkages between terrestrial and freshwater ecosystems across different regions with continuous permafrost in High Arctic. In particular, the research team have three objectives: 1) to quantify and characterize N pools along the ripar...


Permafrost thaw slumps, sediment dynamics and ecosystem health of upland tundra lakes within the western Canadian Arctic
Principal Investigator: Droppo, Ian
Licensed Year(s): 2020
Summary: This licence has been issued for the scientific research application No.4759. The overall objective of this research is to assess the permafrost thaw slump erosion and transport of its sediment by rainfall/runoff to depositional zones within Arctic tundra lakes. To achieve this, we will link a rainfall simulator with an annular flume (to simulate lake currents) located in the Hydro-ecology Moni...


Examining the impacts of climate and environmental change on aquatic and terrestrial ecosystems of the Mackenzie region, NWT
Principal Investigator: Pisaric, Michael FJ
Licensed Year(s): 2018 2017 2016 2015 2014 2013 2012 2011 2010 2009
Summary: This research will continue the long term objective of documenting and understanding the impacts of recent climate change on northern terrestrial and aquatic ecosystems. The short term objectives of my research for 2018 are: 1) to investigate the impacts of permafrost degradation and subsequent thaw slumping on freshwater ecosystems; 2) to examine the limnological implications of drained lakes on ...


Flux of sediment-associated chemical elements in rivers draining to the Arctic Ocean
Principal Investigator: Bogen, Jim J
Licensed Year(s): 2010
Summary: The objective of this research is to estimate the modern and historical fluxes of sediment- associated chemical elements to the Arctic Ocean and their relationships to natural and man-induced changes in sediment yields and sediment sources and if possible, predict the impact of future climate changes on the fluxes. The study will include sampling of overbank sediments from floodplains and del...


Close Encounters: Continued Investigations into 19th-20th Century Copper Inuit and European Intersocietal Interaction
Principal Investigator: Johnson, Donald S.
Licensed Year(s): 2007 2006 2005 2004 2003
Summary: Project a: essentially fifth year of research (sixth-year if associated work in 2000 is counted), and seeks to continue heretofore successful investigations into the nature, substance and long-term effects of contact between Copper Inuit and Europeans/Eurocanadians in the 19th and 20th centuries utilizing sociocultural, archaeological, and economic methodologies, b. Project seeks to initiate a col...


Massive Ice Study in Granular Deposits
Principal Investigator: Pollard, Wayne H
Licensed Year(s): 2006 2005 2004 2003
Summary: Sand, gravel and crushed stone are valuable geological resources, collectively known as aggregates. They are essential bed, foundation and building materials. The presence of massive ice in aggregate deposits results in a series of resource management problems, particularly for the oil industry and its contractors who rely on local granular deposits as building material. From an environmental pers...


Climate forcing factors and the record of climatic variability in the western Canadian Arctic during the past 2000 years
Principal Investigator: Tomkins, Jessica
Licensed Year(s): 2006 2005
Summary: The main goal of this research is to use lake sediment records to examine changes in weather conditions and river discharge in the western Canadian Arctic during the past 2000 years, which will aid in understanding current conditions and forecasting future conditions. The research team will reach the study location by airplane from Resolute, Nunavut, and will be on site from late May to early ...
