Principal Investigator:Patterson, R. Tim Licenced Year(s):
Through analysis of sediment/water interface samples, freeze cores, and dendrochronology the researchers intend to:
i) develop a comprehensive climatic history along a 2° latitudinal gradient in the central NT, variously based on an analysis of freeze cores from lakes along the route of the Tibbitt to Contwoyto Winter Road (TCWR);
ii) determine the relationship between modern lake catchments an...

This licence is being issued for the scientific research application No.1097.
The aim is to understand and reconstruct the extent and dynamics of past glaciers, past climates and ongoing sea level change, including submergence, on Banks Island, through geological mapping and the dating of sea shells, sediment and boulders. The objective is to determine how the environment of Banks Island has ev...

The objectives of the Alaska-Canada Barren Lands Traverse is to: learn about changes in the Arctic from historical observations, to observe commercial and infrastructure changes in relation to how they compare and contrast to the impacts of a warming Arctic climate, and to compile baseline measurements of snow cover physical properties for validation of satellite datasets and snow cover chemical p...
Principal Investigator:Armitage, Derek Licenced Year(s):
The Slave River Delta is one of a series of important delta ecosystems in the Mackenzie Basin. The adjacent community of Fort Resolution depends on its high biological productivity and diversity for both food and resources. Because of climate change, th...
Principal Investigator:Douglas, Marianne Licenced Year(s):
The overall goal of the research is to more fully understand the present-day water quality of arctic lakes and ponds, and to attempt to determine if the water quality of these sites are changing as a result of, for example, recent climatic change or othe...
Principal Investigator:Jette, Helene Licenced Year(s):
The researcher will sample a variety of lakes (some 50 lakes altogether) around Inuvik. A hole, approximately 8 inches in diameter, will be bored through the ice in each lake. Using an Ekman sampler, lake bottom sediments (mud) will be collected for analysis in the lab. The researchers will get to each of the lakes bt helicopter and spend approximately 15 to 20 minutes at each lake....
Principal Investigator:Smol, John Licenced Year(s):
The researchers plan to take samples of lake water and lake sediments from a variety of sites in the region. From these samples, information will be collected about the water chemistry, microscopic organisms present in the lakes, and changes in the region's past environmental and climatic conditions....
Principal Investigator:MacDonald, Glen M Licenced Year(s):
The research party will continue to study past climatic variation and will continue to examine the relationship between climatic change and vegetation response. They will continue lake sediment coring and will collect tree increment cores....

The isotopic compostion of snow and ice is used to reconstruct past climates from records of ice-cores collected in Greenland and Antarctica. The ice cores are a few inches in diameter. Sampling in the Delta may reveal how regionally representative samples of snow are. This will enable the results of ice cores to be evaluated in a regional context....
Principal Investigator:Ritchie, J.C. Licenced Year(s):
Dr. Ritchie is looking at live plants and the remains of plants at the bottom of lakes to see how plants and weather have changed since the glaciers left the Inuvik and Tuktoyaktuk area 10,000 years ago....
