Abstract:

Our understanding of the meridional overturning in the North Atlantic has been developed over the past many decades from modeling, theoretical and observational studies largely conducted in an Eulerian framework.  Starting in the 1990s when drifter and float data became more plentiful, a Lagrangian view of the overturning began to emerge.  This Lagrangian view challenges our conventional understanding of the overturning on a number of fronts, including the temporal and spatial description of the throughput of upper waters from the subtropical to the subpolar gyre and of deep waters from the subpolar to the subtropical gyre.  This talk will draw from studies, both Eulerian and Lagrangian, over the past decade to provide an overview of how of our understanding of the North Atlantic overturning circulation is evolving.
