Principal Investigator: Dixon, O.A.

Summary: In the Arctic Islands, we are studying rocks and the fossils found within these rocks that were formed more than 400 million years ago in warm tropical seas. This study is expected to help in describing the temperatures, climate and water depths of these ancient seas. We are also studying the types of fossil corals and sponge-like animals that are not present in our seas today....

Principal Investigator: Overpeck, Jonathan
Licensed Year(s): 1993 1991 1989
Summary: The goal of our ongoing project is to collect samples of mud from the bottom of several undisturbed lakes on southern Baffin Island. In the laboratory, we will then examine the chemistry, texture and fossils found in this mud in an effort to document how the environment (mainly climate) of this region has changed over the past 2000 years. We hope that this work will eventually aid efforts to imp...

Principal Investigator: Jacobs, John D.
Licensed Year(s): 1994 1993 1992 1991 1990 1988 1987
Summary: This research, begun in 1985, involves measuring climate data such as air and ground temperature, relative humidity, wind speed and direction, solar radiation, precipitation and snow depth. Automatic data collecting stations have been set up to measure these data. The purpose of this research is to document a more accurate picture of the region's climate, to obtain information about the past cli...

Principal Investigator: Burn, Chris R
Licensed Year(s): 1993 1992
Summary: This on-going research involves the assessment of isotopes in snowpack each winter. Collection of snow and ice at various sites along winter roads in the N.W.T. provides information about the composition of isotopes within a region. Isotopic composition of snow and ice taken from ice cores in Greenland and Antarctica have been able to provide information about past climates....

Principal Investigator: Marino, Bruno D.
Licensed Year(s): 1992
Summary: The researcher will sample plants and shells containing records of the stable isotopic composition of the constituents in the environment that are used for growth. The natural abundance of the stable isotopes of carbon in atmospheric CO2 and in dissolved groundwater as well as the hydrogen and oxygen isotopes in water can be related to climatic factors. Thus, these isotope ratios in shells and p...

Principal Investigator: Retelle, Michael J.
Licensed Year(s): 1992 1991 1990
Summary: The researchers will attempt to reconstruct climate and past environmental conditions through recovery and study of sediment cores from lakes at Taconite Inlet, northern Ellesmere Island. They will also monitor conditions under which the lake sediments are presently accumulating....

Principal Investigator: Hicock, Stephen R.
Licensed Year(s): 1992
Summary: The research will involve the study of the interplay (past and present) between glaciers, permafrost, meltwater and seawater on the southwestern side of the Bylot Island ice cap....

Principal Investigator: Koerner, Roy M
Licensed Year(s): 1995 1992 1991
Summary: This is a continuing project to gather information to understand the past climate in the high Arctic. The data will also be used to determine the present climatic trends and pollution levels in the snow....

Principal Investigator: Robinson, Stephen
Licensed Year(s): 1992
Summary: Massive ice is found in exposure in some sections of the Fosheim Peninsula. The exact origin, distribution and characteristics of these ice bodies are largely unknown. Geophysical surveys will be conducted and ice and sediment samples will be taken and analyzed....

Principal Investigator: Morgan, Alan
Licensed Year(s): 1991
Summary: The Researchers will collect sediment samples. Insect fossils will be extracted and analysed. The insect communities recovered will provide an indication of the climatic conditions in the area at the time the sediments were deposited. The age of the sediments will be determined with radiocarbon or other dating methods....
