Eddy forcing of the mean circulation in the western North Atlantic
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1984-08)
This thesis addresses several aspects of the problem of determining the effect of the low-frequency eddy variability on the mean circulation of the Western North Atlantic. A framework for this study is first established ...
Mesoscale variability and mean flow interaction near the Gulf Stream as seen by satellite altimetry and numerical modelling
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 2001-09)
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 ...
A study of the large scale circulation and water mass formation in the Nordic seas and Arctic Ocean
(Massachusetts Institute of Technology and Woods Hole Oceanographic Institution, 1993-10)
In this thesis, production of dense water that feeds the dense overflows across the Greenland-Scotland Ridge has been considered. A new circulation scheme is developed which is consistent with the water masses, currents ...
FVCOM validation experiments : comparisons with ROMS for three idealized barotropic test problems
(American Geophysical Union, 2008-07-26)
The unstructured-grid Finite-Volume Coastal Ocean Model (FVCOM) is evaluated using three idealized benchmark test problems: the Rossby equatorial soliton, the hydraulic jump, and the three-dimensional barotropic wind-driven ...
Age characteristics of a shelf-break eddy in the western Arctic and implications for shelf-basin exchange
(American Geophysical Union, 2008-02-22)
Radioisotope evaluation of a cold-core, anticyclonic eddy surveyed in September 2004 on the Chukchi Sea continental slope was used to determine its age since formation over the shelf environment. Because the eddy can be ...
Horizontal advection, diffusion, and plankton spectra at the sea surface
(American Geophysical Union, 2009-02-04)
Plankton patchiness is ubiquitous in the oceans, and various physical and biological processes have been proposed as its generating mechanisms. However, a coherent statement on the problem is missing, because of both a ...
Correction to “Intraseasonal variability near 10°N in the eastern tropical Pacific Ocean”
(American Geophysical Union, 2007-03-16)
Ocean turbulence, III : new GISS vertical mixing scheme
We have found a new way to express the solutions of the RSM (Reynolds Stress Model) equations that allows us to present the turbulent diffusivities for heat, salt and momentum in a way that is considerably simpler and ...
Zonal circulation across 52°W in the North Atlantic
(American Geophysical Union, 2004-11-18)
In July–August 1997, a hydrographic/Acoustic Doppler Current Profiler (ADCP)/tracer section was occupied along 52°W in the North Atlantic as part of the World Ocean Circulation Experiment Hydrographic Program. Underway and ...
Influence of mixing on CFC uptake and CFC ages in the North Pacific thermocline
(American Geophysical Union, 2004-07-17)
A diagnostic, isopycnal advection-diffusion model based on a climatological, geostrophic flow field is used to study the uptake of chlorofluorocarbons (CFCs) into the portion of the thermocline that outcrops in the open ...
