Physics Colloquium
Dr. Adam Bourassa, University of Saskatchewan
"Volcanoes in the Stratosphere: The View from Space."
The stratosphere is a region of the atmosphere that has been famously known for decades for the depletion of the ozone layer. However, it has recently been recognized that the stratosphere is coupled in important ways to the temperature of the Earth's surface, for understanding both short term weather and long term climate. One of the key parameters of stratospheric composition is aerosol, which, by scattering incoming solar radiation has an overall global cooling impact. Over time, this has a large natural variability due to the impact of energetic volcanic eruptions that can inject aerosol directly to the stratosphere. The Canadian OSIRIS satellite instrument is one of the few operational satellites that can measure aerosol in the stratosphere through a remote sensing technique known as limb scattering. This talk will review the physics involved in making these measurements and highlight several results from the study of recent volcanic eruptions.
When: Friday, March 23rd, 2012 12:30 PM - 1:30 PM
Where: Room 1L11

Department of Anthropology Visiting Speaker Series Presents:
"Prophetic Identities: Indigenous Missionaries on British Colonial Frontier, 1850-75"
Dr. Tolly Bradford, University of Manitoba
Tolly Bradford holds a PhD in History from the University of Alberta. He is currently a research associate in the Department of History at the University of Manitoba and an historical consultant to Canada's Truth and Reconciliation Commission. An expert in nineteenth-century British Christian missions, his work examines the ways in which Christianity has shaped indigeneity, politics, and economy in settler societies like Canada and South Africa. His first monograph, Prophetic Identities: Indigenous Missionaries on British Colonial Frontier, 1850-70, will be published by UBC Press this spring.
Light refreshments and coffee will be provided.
When: Friday, March 23rd 2012, 12:30 PM - 1:30 PM
Where: Room 2M70
