Climate Forcing of Sea Ice: Causes, Consequences and Partnerships

The Arctic climate is changing and this forces sea ice dynamic and thermodynamic processes in very complex ways. This forcing causes change in the geophysics and thermodynamics of the system through a full range of time and space scales, with teleconnections to lower latitudes of our planet. In this presentation, Dr. Barber will review findings from his group that span the micrometer to 1000 km scale in terms of how various scales of climate forcing affect the geophysics of sea ice. He will also review recent changes in these geophysical processes and, in particular, focus on high frequency events and the cascading effects these events have to larger time and space scales. Dr. Barber will then present a summary of the consequences of these geophysical changes in terms of coupled biological, physical and geochemical exchanges across the ocean-sea ice-atmosphere (OSA) interface and provide projections for the expected trajectory and rate of change we can expect in the coming decades. The talk will conclude with an introduction to CEOS partnerships through our national (ArcticNet) and international networks (Arctic Science Partnership (ASP)). Dr. Barber will provide examples of existing and planned large-scale Arctic marine programs and infrastructure in which we seek international collaboration and engagement.

David G. Barber received a Bachelor’s degree (1981) and Master’s degree (1987) from the University of Manitoba, and a Ph.D. degree (1992) from the University of Waterloo, Ontario. He was appointed to a faculty position at the University of Manitoba in 1993 and received a Canada Research Chair in Arctic System Science in 2002. He is currently Associate Dean (Research), The Riddell Faculty of Environment, Earth and Resources. Dr. Barber has published over 240 articles in the peer reviewed literature pertaining to climate change, sea ice dynamic and thermodynamic processes, remote sensing of sea ice, physical-biological coupling in the Arctic marine system and impacts on society (www.umanitoba.ca/ceos). Dr. Barber is recognized internationally through scientific leadership in large network programs (including: NOW, CASES, ArcticNet, CFL, BaySys and CMO). He is an invited member of several Natural Sciences and Engineering Research Council (NSERC) national committees and international committees. He has supervised to completion: 6 honours theses; 26 MSc theses; 22 PhD dissertations and 23 postdoctoral fellows/Research Associates. Twenty-five of his previous students have University positions and 30 work in research, consulting or government. He currently supervises 9 MSc students; 3 PhD students, and 18 Post Doctoral Fellows / Research Associates; leading one of the largest sea ice focused research groups in the world. Dr. Barber is a UM Distinguished Professor, a Fellow of the Royal Society of Canada (Science Academy), and an Officer of the Order of Canada.
