Amundsen 2014 Campaign
Ten NETCARE scientistswere on board the Canadian Coast Guard Ship Amundsen, a research icebreaker, studying atmospheric and oceanic composition throughout the central Arctic. The cruise departed from Quebec City on July 8, entering Lancaster Sound on July 17, undergoing a partial exchange of scientists at Resolute Bay, Nunavut on July 24, before heading west through the Northwest Passage. All NETCARE scientists left the ship on August 14 in Kugluktuk, Northwest Territories.
The scientific goal was to assess the impact of the ocean in promoting the formation of atmospheric aerosols. In particular, as sea ice retreats in years to come, it is important to understand the role that oceans play in affecting Arctic climate. To do this, we took measurements of biogeochemical parameters in the ocean to explore the production of molecules that are released from the ocean to the atmosphere. On the atmospheric side, we measured the concentrations of these gases and their oxidation products, and studied the nature of the ambient atmospheric aerosol particles, including their size, concentration, composition and cloud nucleating abilities.
