Science Objectives

As part of a coordinated international effort to quantify (and eventually monitor) the variability of fluxes connecting the Arctic and Atlantic Oceans and to understand the role played by the Arctic and sub-Arctic in steering decadal scale climate variability, an integrated observing system will provide year-round measurements of volume, liquid freshwater and ice fluxes across Davis Strait. Fluxes through the Strait represent the net integrated Canadian Archipelago throughflow, modified by terrestrial inputs and oceanic processes during its southward transit through Baffin Bay. By the time they reach Davis Strait, Arctic waters already embody most of the transformations they undergo prior to exerting their influence on the deepwater formation sites in the Labrador Sea. This makes the Strait an ideal site for monitoring temporal and spatial variability in the critical upstream boundary condition for Labrador Sea convection. Measurements at Davis Strait will be used to study how fluctuations in the Arctic freshwater system modulate deep water formation to the south, thus influencing the associated meridional overturning circulation (MOC).

Regarding Radioactive Material - Steve Punshon Unv Vic:
"The source is in an electron capture detector in a GC.  It is a permanently sealed source and completely safe, as opposed to open sources, and poses no radiation risk in a regular lab environment.  I will be the only person authorised to operate the instrument.  The GC requires a 20 amp outlet (one of the live/neutral pins is rotated 90 degrees from the normal vertical orientation) and has a relatively short cord, about 6 ft.
