The effects of ocean eddies on tropical cyclones
(Massachusetts Institute of Technology, 2012)
The purpose of this study is to understand the interactions of tropical cyclones with ocean eddies. In particular we examine the influence of a cold-core eddy on the cold wake formed during the passage of Typhoon Fanapi ...
Urea and nickel utilization in marine cyanobacteria as evaluated by incubation, proteomic, and uptake techniques
(Massachusetts Institute of Technology, 2013)
Nitrogen and trace metal biogeochemical effects on phytoplankton productivity were compared through whole water bottle incubations and proteomic evaluation of in situ harvested particulate matter from two distinct oceanographic ...
Vortices in sinusoidal shear, with applications to Jupiter
(Massachusetts Institute of Technology, 2016)
In this thesis, we have studied the existence of vortex steady states in a sinusoidal background shear flow in a 1.75 layer quasi-geostrophic model. Trying to find vortex structures by integrating the Hamiltonian system ...
Abyssal mixing from bottom boundary effects in Mid-Atlantic Ridge flank canyons
(Massachusetts Institute of Technology, 2010)
This paper begins to explore a previously neglected mechanism for abyssal ocean mixing using bottom boundary layer dynamics. Abyssal mixing and the associated upward buoyancy fluxes are necessary to balance the sinking of ...
Ice shelf-ocean interactions in a general circulation model : melt-rate modulation due to mean flow and tidal currents
(Massachusetts Institute of Technology, 2012)
Interactions between the ocean circulation in sub-ice shelf cavities and the overlying ice shelf have received considerable attention in the context of observed changes in flow speeds of marine ice sheets around Antarctica. ...
The response of the Red Sea to a strong wind jet near the Tokar Gap in summer
(Massachusetts Institute of Technology, 2011)
Remote sensing and in situ observations are used to investigate the ocean response to the Tokar Wind Jet in the Red Sea. The wind jet blows down the pressure gradient through the Tokar Gap on the Sudanese coast, at about ...
An inverse approach to understanding benthic oxygen isotope records from the last deglaciation
(Massachusetts Institute of Technology, 2014)
Observations suggest that during the last deglaciation (roughly 20,000-10,000 years ago) the Earth warmed substantially, global sea level rose approximately 100 meters in response to melting ice sheets and glaciers, and ...
Syn-eruptive degassing of a single submarine lava flow : constraints on MORB CO₂ variability, vesiculation, and eruption dynamics
(Massachusetts Institute of Technology, 2010)
Mid-ocean ridge basalts (MORBs) exhibit a wide range of CO2 concentrations, reflecting saturation to supersaturation (and rarely undersaturation) relative to their emplacement depths. In this study, we explore the mechanisms ...
The Influence of heat transport on Arctic amplification
(Massachusetts Institute of Technology, 2019)
The Arctic surface air temperature has warmed nearly twice as much as the global mean since the mid-20th century. Arctic sea ice has also been declining rapidly in recent decades. There is still discussion about how much ...
Oceanic response observations due to passing tropical cyclones : an assessment of drag and sea spray parameterizations
(Massachusetts Institute of Technology, 2016)
Most traditional theories regarding upper oceanic response due to passing tropical cyclones involve an initial and predominant upwelling based on storms' strong cyclonic flow and resulting positive wind stress curl imparted ...
