Rivers and streams in winter: the love-hate relationship of water and ice
Benoit Turcotte, Ph.D., P.Eng, Senior Hydrologist, Yukon Government
Sunday, December 9, 2018, 7:30 pm Beringia Centre, Whitehorse
Most people assume that once the cold season begins, streams freeze and rivers hibernate. However, winter is probably the most dynamic and fascinating period of the year from a hydrology point of view: the first cold nights initiate a tango between the water and the ice that can persist well into the winter season. With snowmelt, the dance recommences, this time leading to the most dramatic expression of northern rivers: breakup. Join Benoit Turcotte as he take you on a journey through winter along different watercourses, highlighting current Yukon hydrology challenges along the way.
Designing Yukon Growing Environments
Bob Sharp, Experiential Science Educator
Sunday, November 25, 2018, 7:30 pm Beringia Centre, Whitehorse
It’s not just a greenhouse. Growing your own food in a Northern Climate requires some special arrangements designed to simulate optimal growth conditions for the plants you wish to grow. Join master tinkerer, Bob Sharp, as he runs through principles, designs and northern technologies used to create such environments. It’s never too early to start planning for the next season.
2nd Annual Ian Church Memorial Lecture
Applied climate research in northern Canada
Dr. Ronald Layden, Manager, North Slave Research Centre, Aurora College, Yellowknife
Tuesday, May 29, 2018, 7:30 pm Beringia Centre, Whitehorse
How is climate change directly affecting Northern communities today, and what are their research priorities as a result? Join Ronald Layden as he describes several related studies: 1) understanding how climate change is impacting basin hydrology and hydroelectric energy production in the NWT; 2) the challenges of using solid waste gasification systems for energy in Northern communities; 3) improving ice roads and increasing their efficiency and 4) a methane survey in the Mackenzie Delta from the Yukon to the Arctic Ocean.
Effects of dust storms on ancient and modern climates in proglacial valleys

In the Yukon, and in other high latitude mountainous areas, warming temperatures within glaciated valleys are causing increased glacial melt. The eroded sediment thus left exposed frequently becomes wind-blown dust. Such events of the past are evident in layers of loess within the surrounding soils. This mineral-rich dust not only provides essential nutrients for aquatic and terrestrial productivity, but also affects the earth’s radiation balance. The extent of its effect is a major source of uncertainty in global climate change models. Join James King as he explores how these dynamics interoperate, with special reference to the Slims River (A'ay Chu) valley.
