Spatial variation in the isotopic composition of snowpack in the Mackenzie Delta area
Principal Investigator: Burn, Chris R
Licenced 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....

Use of Fossil Plants and Shells to Infer Past Climate
Principal Investigator: Marino, Bruno D.
Licenced 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...

Paleoclimatic Significance of Laminated Lake Sediments from the Canadian High Arctic
Principal Investigator: Retelle, Michael J.
Licenced 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....

Ice-rock-water interactions on southwestern Bylot Island
Principal Investigator: Hicock, Stephen R.
Licenced 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....

Ice Core Analysis and Glacier Mass Balance
Principal Investigator: Koerner, Roy M
Licenced 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....

Geophysical Mapping of Buried Massive Ground Ice, Fosheim Peninsula, Ellesmere Island, NWT
Principal Investigator: Robinson, Stephen
Licenced 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....

Fossil and Modern Coleopteran Ecology in Arctic Canada
Principal Investigator: Morgan, Alan
Licenced 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....

Early Quaternary and Late Tertiary Geology and Geomorphology, Arctic Islands
Principal Investigator: Fyles, John G.
Licenced Year(s): 1992 1991 1990
Summary: On Melville and Bathurst Islands, the Researchers will locate and describe the occurrence of high-level gravels and sands, record evidence of the flow-direction of the rivers in which they originated and search for plant and insect fossils that may provide clues about the age of these deposits and about the climate and environment at that time....

Tertiary Palynostratigraphy of the Beaufort-Mackenzie Basin
Principal Investigator: McIntyre, David J.
Licenced Year(s): 1992 1990
Summary: The Researcher and his assistant will collect rock samples for study of the fossil pollen to determine age, correlation with similar material from wells and to determine past climate and environments....

Investigation of Contemporary Sedimentation Patterns in Small Lake Basins, Baffin Island, N.W.T., Canada
Principal Investigator: Miller, Raoul
Licenced Year(s): 1990
Summary: Mr. Miller and Mark Abbott will take water samples and cores from the sediment at the bottom of several lakes on Laird and Becher Peninsulas, Baffin Island. The purpose of the sample collection is to find out about past climate of the area and also to see what impacts human activity in the Arctic might have on these lakes....
