Late Holocene hurricane activity and climate variability in the Northeastern Gulf of Mexico
(Massachusetts Institute of Technology, 2011)
Hurricane activity in the Northeastern Gulf of Mexico and its relationship to regional and large-scale climate variability during the Late Holocene is explored. A 4500-year record of hurricane-induced storm surges is ...
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 ...
Physics of diurnal warm layers : turbulence, internal waves, and lateral mixing
(Massachusetts Institute of Technology, 2017)
The daily heating of the ocean by the sun can create a stably stratified near-surface layer when the winds are slight and solar insolation is strong. This type of shallow stable layer is called a Diurnal Warm Layer (DWL). ...
Linear and nonlinear stratified spindown over sloping topography
(Massachusetts Institute of Technology, 2010)
In a stratified rotating fluid, frictionally driven circulations couple with the buoyancy field over sloping topography. Analytical and numerical methods are used to quantify the impact of this coupling on the vertical ...
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 ...
Submesoscale turbulence in the upper ocean
(Massachusetts Institute of Technology, 2016)
Submesoscale flows, current systems 1-100 km in horizontal extent, are increasingly coming into focus as an important component of upper-ocean dynamics. A range of processes have been proposed to energize submesoscale ...
