Using the past to inform the future: A paleoecological perspective of the impacts of drought and fire on lakes, permafrost and forests
chercheur principal: Pisaric, Michael FJ
Année(s) de permis: 2019 2018 2017 2016
Résumé: The objectives of this research are to examine the frequency and severity of past wildfire and drought (drought-like) conditions in the southern Northwest Territories. Specifically, the research team will examine the following questions: 1) how frequent and severe have fires been in the past; 2) are fires becoming more frequent/severe due to the impacts of climate change; 3) what impact does wildf...

Precambrian banded iron-formations: palaeoceanographic, palaeoclimatic, and palaeobiologic implications
chercheur principal: Aubet, Natalie
Année(s) de permis: 2011 2010
Résumé: The research purpose is intended to better resolve the climatic and oceanic chemical conditions that ultimately led to the origins of animal life and the Cambrian explosion by focusing on the exceptionally well-preserved ancient banded iron formations from the Rapitan Group (NWT, Canada) and the overlying carbonate units. Specifically, detailed analyses of these rocks will help in the understandin...
