Instabilities of an eastern boundary current with and without Large-scale Flow Influence
(Massachusetts Institute of Technology, 2011)
Eastern oceanic boundary currents are subject to hydrodynamic instability, generate small scale features that are visible in satellite images and may radiate westward into the interior, where they can be modified by the ...
Chaotic advection, mixing, and property exchange in three-dimensional ocean eddies and gyres
(Massachusetts Institute of Technology, 2018)
This work investigates how a Lagrangian perspective applies to models of two oceanographic flows: an overturning submesoscale eddy and the Western Alboran Gyre. In the first case, I focus on the importance of diffusion as ...
When an eddy encounters shelf-slope topography
(Massachusetts Institute of Technology, 2016)
Eddies in the ocean move westwards. Those shed by western boundary currents must then interact with continental shelf-slope topography at the western boundary. The presence of other eddies and mean flows complicates this ...
The effect of stratification on wind-driven, cross-shelf circulation and transport on the inner continental shelf
(Massachusetts Institute of Technology, 2012)
Observations from a three-year field program on the inner shelf south of Martha's Vineyard, MA and a numerical model are used to describe the effect of stratification on inner shelf circulation, transport, and sediment ...
Equatorial ocean dynamics impacting upwelling west of the Galápagos Archipelago
(Massachusetts Institute of Technology, 2019)
The Galápagos Cold Pool (GCP) is a region of anomalously cold sea surface temperature (SST) just west of the Galápagos Archipelago. Modeling studies have shown that the GCP is maintained by wind- and current-driven upwelling. ...
Near-inertial and thermal to atmospheric forcing in the North Atlantic Ocean
(Massachusetts Institute of Technology, 2010)
Observational and modeling techniques are employed to investigate the thermal and inertial upper ocean response to wind and buoyancy forcing in the North Atlantic Ocean. First, the seasonal kinetic energy variability of ...
Dynamics of North Atlantic western boundary currents
(Massachusetts Institute of Technology, 2017)
The Gulf Stream and Deep Western Boundary Current (DWBC) shape the distribution of heat and carbon in the North Atlantic, with consequences for global climate. This thesis employs a combination of theory, observations and ...
Circulation and convection in the Irminger Sea
(Massachusetts Institute of Technology, 2010)
Aspects of the circulation and convection in the Irminger Sea are investigated using a variety of in-situ, satellite, and atmospheric reanalysis products. Westerly Greenland tip jet events are intense, small-scale wind ...
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 ...
