The “Canadian/Greenland Data Hole”: …perhaps the most poorly sampled region of the Arctic Ocean! The “Canadian/Greenland Data Hole”: …perhaps the most poorly sampled region of the Arctic Ocean! Freshwater outflows

The “freshwater switchyard”: A good place to detect the origins of freshwater that’s about to leave the Arctic Ocean The “freshwater switchyard”: A good place to detect the origins of freshwater that’s about to leave the Arctic Ocean 3 project components: 1.Large-scale hydrochemical sections (Schlosser + Smethie) 2.Boundary current section at the shelf break (Steele) 3.Sea ice transport studies (Kwok) Large-scale sections Boundary current section …based on Jones et al. (1998); Steele & Boyd (1998); Proshutinsky et al. (2002); Rigor et al. (2002)

Samples to be drawn at Alert. Boundary current survey : helicopter, 6-9 stations CTD-O, XCP, surface layer bottles. …modified from Newton & Sotirin (1997) Sea ice transport studies : satellites u ice : AMSR passive μwave, ENVISAT SAR; h ice : altimeters on IceSAT (laser) & ENVISAT, CryoSAT (radar)
