What? |
A program to study freshwater circulation (sea ice + upper ocean) in the “freshwater switchyard” between Alert (Ellesmere Island) and the North Pole.

Where? |
Sections cross both the Transpolar Drift Stream and the North American Boundary Undercurrent, which vary interannually in composition and strength.

Why? |
This region is historically very poorly sampled, and it lies upstream of North Atlantic deepwater convection sites.
|
How? |
Annual springtime hydrographic surveys:
The LARGE-scale survey (Alert - North Pole by Twin Otter using THICR
The SMALL-scale survey (100 km across the continental slope by helicopter
… also: satellite studies of sea ice transport.
