Hydrology of an Antarctic Polar Desert

The polar deserts of Antarctica are weird places to study hydrology. The more precipitation we get, the less runoff occurs; the ephemeral streams are supplied by glacial melt, yet melt is rarely seen on the glaciers. And the windier it gets, the warmer the air gets, and less runoff occurs.

All of these odd phenomena occur because in summer the ice surfaces are on the cusp of melting and small changes in the energy balance cause big changes in the hydrology.

Archaeological and Paleo-Environmental Research in the Hakai-Luxvbalis Conservancy, Central Coast of BC

Date:
Friday, November 29, 2013 - 15:30 to 16:30
Location:
8-166

Over the last few years a large interdisciplinary effort to examine the cultural and natural history in the Hakai region has been initiated. Supported largely by the Hakai Beach Institute on Calvert Island and in partnership with the Heiltsuk and Wuikinuxv Nations, one aspect of the research involves delineating changes in late Pleistocene and Holocene landscapes, as well as human lifeways in this highly productive, resource rich area.

Critical Habitat Planning: More Than Just Lines On a Map

Woodland caribou (Rangifer tarandus caribou) in Alberta, Canada, are designated as threatened due to their reduced distribution, a decrease in the number and size of populations, and threats of continued declines associated with oil and gas extraction and forestry industries. Assessing and managing cumulative effects of human activities on caribou and providing adequate habitat to allow for its persistence is of critical importance.

Saga of the Spruce Beetle Outbreak in the Bowron

Date:

Location:

Strong winds approaching 150 km/hour in October 1975 caused widespread spruce blow-down and breakage in the upper Bowron river valley and to a lesser extent, in adjacent valleys. Several warm winters with heavy snow packs and early springs set the conditions for one-year life cycle spruce beetles. Overlapping one and two-year cycle beetles resulted in huge beetle flights and dramatic expansion and intensification of the infestation.

Talking to Trees: A Dendrochronological Assessment of the Atmospheric Pollution Effects of Athabasca Bitumen Mining Downwind From the Industry

Date:

Location:

Bitumen mining in Alberta is considered one of the largest economic vehicles in Canada, but the assessment of this industry's environmental impacts is incomplete. The region downwind of this pollution source is occupied by an Indigenous population concerned for the health and viability of their territory.
