Tabatha Rahman will be presenting Ice-Wedge Volume, Distribution, and Development in the Barrens of the Hudson Bay Lowlands, Northern Manitoba.
Date: 15 May 2024
Time: 13:00-14:00 Eastern Time
Location: Zoom (details are posted in our Teams site).
Extensive ice-wedge polygon networks are found in the ‘Barrens’ of northern Manitoba, a 50,000 km2 zone of continuous permafrost tundra that emerged from the Tyrrell Sea less than 5,500 years ago. Tabatha will present empirical results of ice-wedge volume and tri-dimensional distribution, and will focus on the environmental conditions associated with the growth and degradation of ice wedges in this uplifted permafrost peatland. Knowledge of wedge-ice morphology and development is essential for the prediction and mitigation of risks associated with anticipated permafrost thaw in the Barrens.
