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). ...
Influences on the oceanic biogeochemical cycling of the hybrid-type metals, cobalt, iron, and manganese
(Massachusetts Institute of Technology, 2012)
Trace metal cycling is one of many processes that influence ocean ecosystem dynamics. Cobalt, iron, and manganese are redox active trace metal micro-nutrients with oceanic distributions that are influenced by both biological ...
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 ...
Geophysical and geochemical constraints on the evolution of oceanic lithosphere from formation to subduction
(Massachusetts Institute of Technology, 2017)
This thesis investigates the evolution of the oceanic lithosphere in a broad sense from formation to subduction, in a focused case at the ridge, and in a focused case proximal to subduction. In general, alteration of the ...
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 ...
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, ...
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 ...
