Petrology and geochemistry of the late Archaean banded iron formation and associated turbidites, western Slave Craton: constraints on palaeoenvironment
Principal Investigator: Haugaard, Rasmus RH
Licenced Year(s): 2013 2012
Summary: The recent discovery of new occurrences of 2.9 - 2.6 Ga old banded iron formations in the NWT have opened an exceptional opportunity to study ocean chemistry directly preceding the Great Oxidation Event (GOE). In this regard, the research group has been engaged with the Northwest Territories Geoscience Office (NTGO) to undertake field and laboratory studies of Achaean Banded Iron Formation (BIF) f...


Hay River Ice Jam Study
Principal Investigator: Hicks, Faye E
Licenced Year(s): 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004
Summary: The objective is to study ice processes on the Hay River in order to continue the ongoing development of computer models to predict them. Also, the team has developed some flood warning tools for the community and we are interested in testing and enhancing them. In order to develop realistic models, it is important that the researchers have the opportunity to observe river breakup so as to hav...


A phylogenetic and phylogeographic study of predaceous diving beetles in the Nearctic with a focus on the tribe Agabini (Coleoptera, Dytiscidae, Colymbetinae).
Principal Investigator: Venables, Chandra
Licenced Year(s): 2011
Summary: The objectives of this research project are to: 1) establish evolutionary relationships of diving beetles in the Nearctic, in addition to identifying colonization routes for exemplars in the tribe Agabini; 2) assess genetic diversity of target species and among-population genetic mixing, and compare these data to historical data (where possible) with an aim at assessing latitudinal and historica...


Present and Past Hydrology, Ecology and Climate of the Mackenzie Basin Deltas
Principal Investigator: Wolfe, Brent BBW
Licenced Year(s): 2007 2006 2005 2004 2003 2002
Summary: Summer 2005 field activities will focus on continuing multi-year studies of the modern hydrology and ecology of the Slave River Delta. The aim of this research is to improve knowledge of changes in lake water balance and chemistry and the subsequent responses of aquatic plants over seasonal and inter-annual time-scales under varying climatic and hydrological conditions. Overall, this information...


Public archeology for the 21st century: Collaboration with an Arctic community
Principal Investigator: Lyons, Natasha L.
Licenced Year(s): 2006 2005
Summary: This project was first suggested by the Aklavik Community Corporation and is a collaboration between the researcher and the community. The Inuvialuit community in Aklavik recognizes that Elders' knowledge is being lost very quickly and this has spurred...


2000 Years of Climate Change at Treeline North of Yellowknife
Principal Investigator: MacDonald, Glen M
Licenced Year(s): 2005
Summary: The researchers believe that the treeline zone is one of the most sensitive areas on earth to temperature changes, both natural and caused by global warming. They would like to take a small core (5 cm diameter) from the mud at the bottom of two small lakes close to Back Lake, northeast of Yellowknife. In the laboratory, they will analyze the cores for temperature-sensitive aquatic insect remains...


Permafrost and climate change, western Arctic Canada
Principal Investigator: Burn, Chris R
Licenced Year(s): 2017 2016 2015 2014 2013 2012 2011 2010 2009 2008 2007 2006 2005 2004 2003 2002 2001 2000 1999 1998
Summary: The researchers hope to measure ground temperatures to find out how they are changing as a result of climate change. They will try to find out how the thickness of the snow cover affects the amount of ground warming that has occurred over the past 35 years. The researchers will study the cracking of ice wedges to find out if they are cracking less now than they did in the 1970s and 1980s. The...


Holocene Environment Change Across Treeline, Mackenzie Delta Region
Principal Investigator: Pisaric, Michael FJ
Licenced Year(s): 2008 2007 2006 2005
Summary: There are three main parts in the researchers' project: 1) investigating changes in vegetation cover in the Inuvik region during the past 10,000 years using fossil pollen and stomata preserved in lake sediment; 2) investigating the importance of disturb...


Climate forcing factors and the record of climatic variability in the western Canadian Arctic during the past 2000 years
Principal Investigator: Tomkins, Jessica
Licenced Year(s): 2006 2005
Summary: The idea of the study is that researchers use the layers of sediment in a lake-bottom to figure out what the climate was like every year from last year to 2000 years ago. The researchers want to 1) look at cores of lake-bottom sediment that show layers...


Field measurements to constrain data for use in a numerical model which will quantify the growth, maintenance and disappearance of thaw lakes over time scales of tens to thousands of years
Principal Investigator: Plug, Lawrence
Licenced Year(s): 2004
Summary: The overall objective of this research is to construct and test predictive computer models that show the evolution of lowland permafrost landscapes. Surveys and radiocarbon dating of drained basins will be undertaken and canoe-based surveys will determin...
