Constraints To Ecosystem Development in High Arctic Polar Deserts
Principal Investigator: Bliss, Lawrence
Licenced Year(s): 1994
Summary: We seek to better understand how ecosystems develop in the high arctic following retreat of ice caps. This includes studies of soil development and the influence that rocks play in this as well as studying the development of block crusts of organisms that form on the soil surface. We will also try to understand the role these crusts play in fixing nitrogen and influencing the development of flower...


Contaminant deposition measurements in precipitation in the NWT
Principal Investigator: Gregor, Dennis J.
Licenced Year(s): 1994 1993
Summary: There is only limited information on contaminant trends in arctic ecosystems. This long-term study is examining the amounts of contaminants present in arctic ice caps. By taking core samples from ice caps, the researchers are able to measure the levels of contaminants that have been deposited by precipitation over many years. This study will also improve our understanding of the levels of conta...


The role of soil algae in high arctic ecosystem development
Principal Investigator: Bliss, Lawrence
Licenced Year(s): 1993 1992 1991 1989 1988
Summary: The researcher will continue his long term work on plants in a high arctic polar desert. More specifically, this study will examine the small organisms that live in the soil and how these organisms interact with and provide benefits to plants....


University field course on the arctic environment
Principal Investigator: Howarth, Phil
Licenced Year(s): 1993
Summary: The three professors from the University of Waterloo will lecture the students on the subjects of ecology, geology and climate and conduct field trips in the vicinity of Igloolik and Iqaluit. The students will select topics to study while in Igloolik: their studies will be assessed and assigned a grade....


Inter-relationships Between Internally Feeding Insects and Species "Pedicularis" in the High Arctic
Principal Investigator: Meier, Sharon
Licenced Year(s): 1991 1990
Summary: The Researcher will continue to study plant-insect relationships and factors which play determining roles in the lives of organisms inhabiting the Arctic environment....


The Creation and Utilization of an Artifical Reef in the Churchill Region
Principal Investigator: Thornton, Sheila
Licenced Year(s): 1990
Summary: The Researcher will create an artifical reef in the Churchill region and develop an arctic ecosystem study site. She will create a species inventory which will involve benthic sampling using SCUBA gear. Species include benthic marine invertebrates, fish and pelagic invertebrates found in 0-20 metres of water....
