The North Atlantic is a special place where the ocean circulation has an important influence on Earth’s climate. The deep flow in particular plays a critical role and the fluid dynamics of the surface-to-sea-floor circulation is subtle and sensitive to extrinsic forcing. This Thursday, September 26th, 2013 at 4:00pm in MIT Room 56-114, Thomas W.N. Haine (the Morton K. Blaustein Professor and Chair of the Department of Earth & Planetary Sciences at Johns Hopkins University) will focus on the Denmark Strait, where the flow is channeled by bathymetry and dense Arctic waters overflow a shallow gap into the deep North Atlantic. Haine will simulate the fluid dynamics of this region using numerical circulation models, as well as compute the trajectories of 10,000 Lagrangian particles to elucidate the fluid kinematics and diabatic mixing processes. This approach illuminates the nature of the overflow and suggests ways in which it can be efficiently monitored. The role of scientific computing is central to these efforts, and is emphasized throughout.
