The objective of this research is to explore the influence of temperature and disturbance on green alder by comparing alder characteristics on sites with different average temperatures and disturbance histories. Understanding of factors that influence alder populations today will assist in predicting the likely consequences of rising temperatures and increased disturbance on tall shrubs.

Summary:
The research team proposes to collect ice cores and liquid water from the Mackenzie River adjacent to the Town of Inuvik. The research team will then examine the concentration of the naturally occuring, stable isotope of oxygen (oxygen -18) in these ice and water samples, and determine how these concentrations differ in Northern Alaska and Canada. All samples will be taken to the University of A...

Summary:
The research will require fieldwork in the Richardson Mountains between 27 April and 8 May, 2001. Research will involve the development of a high-resolution paleoenvironmental record based on lake sediments from up to six lakes in the Richardson Mountains and the Melville Hills in the NWT. Transportation in the field for the Dempster Highway study will be by snowmobile and snowshoes. If snow cov...

The primary objectives of the project are to map the coastline of the Canadian Beaufort Sea in terms of its sensitivity to coastal erosion and monitor changes in the coastline, and to collect information on the morphology of the coast and the sediments which compose it for use in developing and calibrating predictive models of coastal change. In order to achieve these objectives previously proven ...

Summary:
Arctic clouds are dominant on average covering 40 to 60% of the skies over the Arctic ocean. They exert a large influence on the radiation balance in the Arctic, where climate change effects are predicted and observed to be largest in the northern hemisphere. The FIRE III field project will use in-situ measurements obtained using instrumental aircraft, in combination with concurrent satellite dta,...

Summary:
Soil (at seven depths) and air temperature data are recorded by data loggers. These loggers are programmed to collect data every 3 hours on the hour. The sites are visited twice a year to reprogram the loggers. In addition, active layer depth and subsidence are also recorded during the fall visit. Researchers will collect this data in order to determine the effect of climate change on the envi...
