The objectives of this research project are to: 1) determine if the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system; 2) determine how these two types of feedback differ between the discontinuous and continuous permafrost zones; 3) determine if the reported decrease (increase) in net CO2 (CH4) exchange based on plot- (<1m2) and ecosystem-scale...

The objectives are to draw together multiple sources of information so that we may (1) examine change in lake area in this ecoregion, (2) assess amount of meadow habitat lost to rising water levels in core bison range, (3) investigate whether recent changes are part of a longer-term cycle and evaluate the causes of this change, (4) determine a way to document and integrate local and traditional kn...

The research team intends to study how important greenhouse gases, carbon dioxide and methane, are exchanged between tundra surfaces and the atmosphere. They will measure these exchanges over various tundra types and relate them to environmental variables such as soil properties and weather, in hopes of understanding more about how future climate change will impact the land surface and how these i...

The research team seek to understand carbon dynamics during warm climate intervals in the Arctic: the Holocene Thermal Maximum (HTM) the warmest pre-industrial interval ranging in timing from 10 ka (thousands of years before present) with maximum seasonality to 6 ka with reduced seasonality, and the Medieval Climate Anomaly (MCA) at ~1 ka with similar seasonality as today. By studying peat cores f...

The primary objective of this research is to ensure safe and sustainable industrial and community development by improving the understanding of coastal and nearshore seabed processes and properties. The research provides the means to improve the knowledge of physical conditions in the coastal zone in order to help government agencies, corporations, and local residents understand, mitigate and redu...

The objectives of the research are: (1) measure the spectral properties (i.e. how light is absorbed and reflected) and biochemical constituents (e.g. chlorophyll, water, nitrogen, carbon) of arctic vegetation at the ground-level in various vegetation communities across the Western Arctic (e.g. low-arctic to high-arctic); (2) investigate the potential of using satellite based multi-angular imaging ...

The central logistics hypothesis is that a crucial component of an Arctic Observing Network is ocean thermistor string buoys that are capable of measuring the local, atmospherically warmed upper 60 m of the Arctic Ocean. The focus is on the increasingly open seas of the Canadian and eastern Eurasian Basins.
The central scientific hypothesis that provides motivation for this proposal is that the...

Uniform permafrost and ground surface temperature measurements are one of the more important databases for long-term climatic study as well as remote sensing ground truthing data. Consistency in sensor depth, casing and drilling methods helps in comparison of the spatial and temporal distribution of the permafrost and seasonal conditions. The proposed partnership with the schools aids continuous m...

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...
Principal Investigator:Lamoureux, Scott F Licenced Year(s):
The research team seeks to obtain sediment cores from two lakes in order to reconstruct past river flow in the region. This work, which builds on similar efforts at "Shellabear" lake, NWT, and work at Cape Bounty (Nunavut), will focus on long term river flow characteristics and the climate factors that control them.
The fieldwork involves augering a hole in the lake ice and lowering a tube int...
