Abstract

Smethie In collaboration with a previously funded program by Pickart (WHOI), the PIs will contribute to the identification of the origin of Classical Labrador Sea Water (CLSW) in the Irminger Basin, map the pathways of CLSW, Denmark Strait Overflow Water (DSOW), and Iceland-Scotland Overflow Water (ISOW) IN THE Irminger Basin, estimate the rate of DSOW flow to the Irminger Basin, and document variations of DSOW and ISOW in the Irminger Basin and the source of these variations. They will use, primarily, CFC-11, -12, and -113. They will perform inverse modeling to understand diapycnal mixing in the Deep Western Boundary Current and controls on how the overflow water mixes with and entrains surrounding waters.
