The seasonal and interannual variability of the West Greenland current system in the Labrador Sea
(Massachusetts Institute of Technology, 2010)
The Labrador Sea, as one of a few places of deep water formation, plays an important role in the Meridional Overturning Circulation. While the interior of the Labrador Sea, where the deepest convection takes place, is known ...
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 ...
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 ...
Mechanisms for enhanced turbulence in the Drake Passage Region of the Southern Ocean
(Massachusetts Institute of Technology, 2016)
The Southern Ocean is one of the most energetic regions of the world ocean due to intense winds and storm forcing, strong currents in the form of the Antarctic Circumpolar Current (ACC) interacting with steep topography, ...
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 ...
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 ...
Physical controls on copepod aggregations in the Gulf of Maine
(Massachusetts Institute of Technology, 2013)
This thesis explores the role that the circulation in the Gulf of Maine (GOM) plays in determining the distribution of dense aggregations of copepods. These aggregations are an important part of the marine ecosystem, ...
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 ...
