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 ...
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 ...
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 ...
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 ...
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. ...
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 ...
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 ...
Energy pathways and structures of oceanic eddies from the ECCO2 State Estimate and Simplified Models
(Massachusetts Institute of Technology, 2013)
Studying oceanic eddies is important for understanding and predicting ocean circulation and climate variability. The central focus of this dissertation is the energy exchange between eddies and mean ow and banded structures ...
The production of temperature and salinity variance and covariance : implications for mixing
(Massachusetts Institute of Technology, 2013)
Large-scale thermal forcing and freshwater fluxes play an essential role in setting temperature and salinity in the ocean. A number of recent estimates of the global oceanic freshwater balance as well as the global oceanic ...
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 ...
