Bering Sea storms introduce various environmental conditions that adversely affect human activity and infrastructure in the coastal zone and the ecosystems they depend upon. Storm impacts include interactions with sea ice in all potential states: large floes, shore-fast ice, and incipient sea-ice in frazil or slush state. In particular, sea ice can act to enhance or mitigate the impacts of adverse marine state, even as the event is occurring. Such occurrences should be part of a forecasting regimen, however scientific work has not been conducted on this phenomena, with the result that a physical model describing the formation of slush ice berms does not exist. To arrive at such a model requires visits to and input...
David is a professor in the Department of Geography at University of Victoria, a position he has held since 2010. For the six years prior to that, he was a research scientist and professor at UAF’s International Arctic Research Center/Department of Atmospheric Sciences. He also held Post-Doc positions at Bedford Institute of Oceanography, focusing on environmental forcing of arctic coastal regions (2002-2004), and the University of Ottawa, focusing on high-arctic data issues and computer methods for hemispheric paleo-climate reconstruction (2000-2002). His PhD focused on high-arctic climate issues His primary interests centre around the “environmental forcing” of coastal zones and the analysis of large-scale weather...

This project engaged several Western Alaska coastal communities to describe types and formation processes associated with near-shore sea-ice phenomena during the fall freeze-up season, in particular as relevant to coastal erosion, flooding, and shoreline protection. Commentary and indigenous and local observations were drawn from and analyzed through existing community observing programs (SIZONet and ANTHC-LEO) as well as from new interviews and meetings conducted for this project. Extensive work was performed to summarize, assess, and synthesize written and recorded observations and commentary. A primary result was identification of a range of slush-ice berm events that could be broadly categorized as “advective”...
