This research aims to understand what factors affect 1) the amount of carbon stored in tundra soils, and 2) the conversion of this soil carbon into greenhouse gases (carbon dioxide and methane). In particular, the research team wants to understand how hydrology (which is the distribution and movement of water in soils and streams) might affect the carbon cycle under future global warming. This inc...

Through this project the principal investigator will address the following objectives: What is the net effect of permafrost thawing-induced biophysical and biogeochemical feedbacks to the climate system? How do these two types of feedback differ between the discontinuous and continuous permafrost zones? Is the reported decrease (increase) in net Carbon Dioxide (CO2)-Methane (CH4) exchange based on...

The objective of this study are to quantify the amount of chemical weathering that takes place in the Mackenzie River Basin, to quantify how much weathering of silicate rocks is done by carbonic acid versus sulfuric acid, and to quantify the chemical weathering of fossil organic carbon. The overall aim is therefore to assess the carbon balance of the whole river basin and to place constraints on ...

The possibility of climate warming demands detailed analysis of the carbon budget in boreal forest ecosystems as they may be major carbon sinks. The data from previous years suggest that forests may be losing carbon to the atmosphere. Due to large annual variation in carbon accumulation, measurements covering several years are necessary.
Soil and air temperature, and soil moisture will be meas...

The purpose of this study is to examine carbon exchange between the arctic tundra and the atmosphere. Specifically, the researchers are interested in variation in carbon exchange in response to environmental factors such as soil moisture and weather (tem...

The project will focus on understanding, analyzing and evaluating the reactions of the northern boreal forest ecosystems in the Great Slave Lake region due to man made stress of mining, settlement and connecting activities. The project will try to develop some general conclusions, statements and model systems. The research team (2 persons) will come from Europe to Yellowknife by plane. The base wi...
Principal Investigator:Robinson, Stephen Licenced Year(s):
Research will be conducted in a peatland complex approximately 12 km west of Fort Simpson (4 km west of the Wrigley Road). The major component of the field work will include the collection of peat cores in both frozen and unfrozen terrain to about 1 m depth. A total of approximately 100 cores will be collected. Core holes will be approximately 15 cm wide, and will be filled to minimize terrain ...
