Variability of zooplankton and sea surface temperature in the Southern Ocean
(Massachusetts Institute of Technology, 2006)
Interactions between physical and biological processes in the Southern Ocean have significant impacts on local ecosystems as well as on global climate. In this thesis, I present evidence that the Southern Ocean circulation ...
Production and analysis of a Southern Ocean state estimate
(Massachusetts Institute of Technology, 2006)
A modern general circulation model of the Southern Ocean with one-sixth of a degree resolution is optimized to the observed ocean in a weighted least squares sense. Convergence toward the state estimate solution is carried ...
Comparison of wind stress algorithms, datasets and oceanic power input
(Massachusetts Institute of Technology, 2009)
If the ocean is in a statistically steady state, energy balance is a strong constraint, suggesting that the energy input into the world ocean is dissipated simultaneously at the same rate. Energy conservation is one of the ...
On the warm bias along the South-West African Coast in coupled models : an oceanic perspective
(Massachusetts Institute of Technology, 2008)
Coupled ocean/atmosphere simulations exhibit systematic warm biases over the South West African (SWA) coastal region. Recent investigations indicate that coastal ocean dynamics may play an important role in determining the ...
Evolution of the Irminger Current anticyclones in the Labrador Sea from hydrographic data
(Massachusetts Institute of Technology, 2006)
The continuous supply of heat and fresh water from the boundaries to the interior of the Labrador Sea plays an important role for the dynamics of the region and in particular, for the Labrador Sea Water formation. Thus, ...
Mesoscale variability and mean flow interaction near the Gulf Stream as seen by satellite altimetry and numerical modelling
(Massachusetts Institute of Technology, 2001)
The interaction between the eddy field and the mean flow near the Gulf Stream is studied here using satellite altimeter measurements and an eddy resolving numerical model. The eddy vorticity flux in the quasigeostrophic ...
Arctic Ocean circulation in an idealized numerical model
(Massachusetts Institute of Technology, 2008)
The mid-to-deep Arctic Ocean is generally characterized by a cyclonic circulation, contained along shelves and ridges. Here we analyze the general Arctic circulation using an idealized numerical model consisting of a ...
Winter mixed-layer development in the central Irminger Sea : the effect of strong, intermittent wind events
(Massachusetts Institute of Technology, 2006)
The impact of the Greenland tip jet on the wintertime mixed-layer of the southwest Irminger Sea is investigated using in-situ moored profiler data and a variety of atmospheric data sets. The mixed-layer was observed to ...
Submesoscale coherent vortices in the deep Brazil Basin
(Massachusetts Institute of Technology, 2000)
With Lagrangian and hydrographic data taken in the deep Brazil Basin, we identify several submesoscale coherent vortices (SCVs). These features contrast with SCV paradigms in that float data indicate approximately equal ...
Linear and nonlinear Rossby waves in basins both with and without a thin meridional barrier
(Massachusetts Institute of Technology, 2002)
The linear and nonlinear Rossby wave solutions are examined in homogeneous square basins on the [beta]-plane both with and without a thin meridional barrier. In the presence of the meridional barrier the basin is almost ...
