Slope/shelf circulation and cross-slope/shelf transport out of a bay driven by eddies from the open ocean
(Massachusetts Institute of Technology, 2009)
Interaction between the Antarctic Circumpolar Current and the continental slope/shelf in the Marguerite Bay and west Antarctic Peninsula is examined as interaction between a wind-driven channel flow and a zonally uniform ...
Ice shelf-ocean interactions in a general circulation model : melt-rate modulation due to mean flow and tidal currents
(Massachusetts Institute of Technology, 2012)
Interactions between the ocean circulation in sub-ice shelf cavities and the overlying ice shelf have received considerable attention in the context of observed changes in flow speeds of marine ice sheets around Antarctica. ...
Diapycnal advection by double diffusion and turbulence in the ocean
(Massachusetts Institute of Technology, 1999)
Observations of diapycnal mixing rates are examined and related to diapycnal advection for both double-diffusive and turbulent regimes. The role of double-diffusive mixing at the site of the North Atlantic Tracer Release ...
Buoyancy-driven circulation in the Red Sea
(Massachusetts Institute of Technology, 2014)
This thesis explores the buoyancy-driven circulation in the Red Sea, using a combination of observations, as well as numerical modeling and analytical method. The first part of the thesis investigates the formation mechanism ...
Internal hydraulic jumps with upstream shear
(Massachusetts Institute of Technology, 2017)
Internal hydraulic jumps in flows with upstream shear are investigated numerically and theoretically. The role of upstream shear has not previously been thoroughly investigated, although it is important in many oceanographic ...
Investigating the role of Trichodesmium spp. in the oceanic nitrogen cycle through observations and models
(Massachusetts Institute of Technology, 2014)
This work concerns the nitrogen fixation and abundance of Trichodesmium colonies in the western subtropical-tropical North Atlantic and their connections with physical processes. Data were collected in fall 2010 and spring ...
Stability of large-scale oceanic flows and the importance of non-local effects
(Massachusetts Institute of Technology, 2009)
My thesis covers two general circulation problems that involve the stability of largescale oceanic flows and the importance of non-local effects. The first problem examines the stability of meridional boundary currents, ...
