Summary: The objectives of this research are to: (1) Confirm of a meteorite impact origin for the Collinson Inlet structure. In order to confirm the meteorite impact origin of this structure, unequivocal shock metamorphic criteria need to be documented. Shatter cones are the only diagnostic shock effect visible to the naked eye (French and Koeberl 2010). The research team will seek out the potential s...

Summary: It is believed that during the last ice-age on northern Ellesmere Island, Lake Hazen was `pushed' further south as a result of the presence of glaciers. The researchers are investigating the Lake Hazen Basin area to determine the nature of this ancient lake. Sediment samples will be taken from both Lake Hazen as well as the surrounding area to study the past environment and organisms (now fossils...

Summary: The Cambrian period is an interval of geologic time that is poorly known in arctic Canada. Previous studies have been very basic and almost no fossils have been recovered. Sections of sedimentary rock will be measured in detail, with attention focused on the structure of the sediments as well as the presence of fossils. A map will then be constructed showing the layers in which fossils occur. ...

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: Stromatolites are variously shaped mounds or reefs composed of sediments and the fossilized remains of single-celled marine organisms called blue-green algae. There are massive fossil reefs located on Baffin Island which are some of the largest known of their age. By studying the structure, form and chemical make-up of these reefs, information about the ancient ocean and the growth of ancient re...

Summary: The Researcher will continue to investigate lakes on the unglaciated terrain of Fosheim Peninsula to determine the former environments of high and low arctic lakes. By analyzing the physical and chemical properties of the sediments, as well as the preserved biological remains within them, the nature and timing of rapid environmental changes at the close of the last glaciation may be explained....

Summary: The Researcher and his team will study the age, chemistry and fossil organisms preserved in the lake sediments of the Truelove Lowland and similar coastal lowlands. The information will be used to reconstruct the environmental changes that have taken place in these Polar Oases during the last 40,000 years....
