Arctic summer sea ice is declining rapidly: a trend with enormous implications for global weather and climate. Now in its eighth year, the multi-year Arctic Switchyard project is tracking the Arctic seascape to distinguish the effects of natural climate variability from human-induced climate change. The University of Washington is leading the project.
- A) The Canadian Forces Station, Alert
We will fly from the Canadian military base at Alert, Ellesmere Island, land on the ice by ski plane to drill holes, deploy instruments and retrieve water samples. We will measure water temperature, salt content and levels of dissolved oxygen, and a wide variety of natural and man-made substances. Our goal is to understand how much fresh water is entering the system, where it is coming from (sea ice melt, river run-off and so on) and where it exits the arctic, altering currents in the North Atlantic Ocean.
During the next few weeks we will blog from the field; Follow our work on the Arctic Switchyard project page.
