Summary: The study will measure carbon dioxide (CO2) and methane (CH4) fluxes at Illisarvik during the peak of the growing season using a combination of eddy covariance and gas chamber methods. The primary objective will be to determine the magnitude of CO2 and CH4 fluxes and determine whether sequestration offsets emission. Secondary objectives will be to observe the temporal and spatial variability of th...

Summary: This research is physically based on a peat plateau and a peat bog, both close to Yellowknife. There are two primary objectives to this research. The first involves quantifying surface energy balances in areas where degradation of peat is pronounced and where it is not. Suprapermafrost water from the degraded and non-degraded sites will be analyzed for nutrients and dissolved organic carbon (DOC) ...

Summary: This study will examine the solar degradation of riverine dissolved organic carbon (DOC) to carbon dioxide (CO2) throughout the Mackenzie River Delta. During the spring runoff peak just before summer solstice, ice-jam flooding inundates the Delta with river water, which spreads out in a relatively thin layer over an extended area and is exposed to 24-hour Arctic sunlight. This water is then slowly...

Summary: The objective of this research project is to make time-series measurements of the CO2 system in the Mackenzie River, near Inuvik, Northwest Territories. Monthly water sampling is taking place at the Mackenzie River near Inuvik by technicians from the Aurora Research Institute. Data will be shared with local communities for education purposes as well as annual reports and publications made avail...

Summary: The overall aim is to assess the carbon balance of the Mackenzie River Basin and to place constraints on the role of climatic and physical erosion processes in driving carbon dioxide source and sinks to the atmosphere and oceans. More specifically, the researchers aim to quantify the amount of chemical weathering that takes place in the Mackenzie River Basin; to quantify how much weathering of sil...

Summary: The aim of this project is to study how greenhouse gases are exchanged between tundra and atmosphere. This will be related to environmental variables, such as soil and weather, to understand how climate change will impact the land, and in turn how these impacts might influence the climate. Previous measurements indicate that tundras near the Daring Lake Research Station are a net sink for CO2 d...

Summary: Northern forests are closely connected to the issue of global warming because they are likely to absorb much of the carbon dioxide that is emitted into the air by humans. The amount that these forests absorb, however, is not clear. The research team will...

Summary: Accurate estimates of the bulk density or specific gravity, tilt angle and average diameter of various size classes must be established. This study focuses on collection and validation of these estimates, recognizing that they may indeed change, dependin...

Licensed Year(s): 1995
Summary: The researchers will field collect and preserve dwarf willow leaf specimens. Further, note will be made of habitat of specimens (aspect; slope angle; drainage; accompanying vegetation; etc). Site locations will be determined using a global positioning system altitude/latitude/longitude) for map plotting. Samples will be analysed on return to the United Kingdom for leaf stomatal density (an indi...

Summary: The researchers will be examining small marine organisms (algae, zooplankton and phytoplankton) to determine their influence on global warming. Carbon is necessary for the production of carbon dioxide (CO2), and increase levels of CO2 in the atmosphere can contribute to an increase in the earth's overall temperature. The study will examine how these small marine creatures can reduce carbon level...
