HE44C:
The Beaufort Sea in Transition: Responses to Climate Change and Human Impacts II Posters


Session ID#: 9626

Session Description:
The Beaufort Sea comprises a seasonally ice-covered and comparatively shallow shelf characterized by the strong influence of productive waters from the Chukchi Sea in the west and high riverine inputs along the entire shelf, peaking in the east with the Mackenzie River. Over a steep slope, shelf waters interact with the complex hydrography of the deep Canada Basin. This interface between the coast of North America and the open Arctic Ocean is experiencing sea ice retreat, increased coastal erosion, enhanced primary productivity and upwelling, and oil and gas exploration. We welcome scientists from all disciplines of the ocean-science community to submit abstracts for this session to help advance our knowledge of the status and processes that define this critical interface and its response to climate change and human impacts. We are especially interested in abstracts that link aspects of circulation, primary productivity, nutrient and carbon chemistry, arctic contaminants and/or the structure and function of biological communities to environmental forcing factors.
