Summary:
For much of the Earth's history, the arctic has had a mild climate, quite unlike the conditions that now exist. Evidence that supports this past climate are fossil plants and animals (including crocodiles and tortoises) found in the arctic. The Earth's magnetic field has changed over time and these changes are contained in the fossils. This research will try develop a technique to age these fos...

199219901988 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....

19911989 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...

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...

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....

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....

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....

Summary:
To continue a study of recent glacial, river and marine sediments (fossils) and deposits to develop a record of the recent environments (climates)....
