Simulated Dynamic Balances for Mid-Ocean Mesoscale Eddies
Publisher: American Meteorological Society
Abstract: Eulerian potential vorticity and heat balances calculated for a multi-layered quasi-geostrophic model are shown to be consistent with those inferred from the MODE data. Above the thermocline the balances are the result of ...
A Statistical Description of the Vertical and Horizontal Structure of Eddy Variability on the Edge of the Gulf Stream Recirculation
Publisher: American Meteorological Society
Abstract: The vertical structure of eddy variability on the southern edge of the Gulf Stream recirculation is presented as a number of different forms of empirical orthogonal modes. The velocity dot-product modes show more barotropic ...
A Synoptic and Statistical Description of the Gulf Stream and Subtropical Gyre Using SOFAR Floats
Publisher: American Meteorological Society
Abstract: Trajectories of 17 SOFAR floats ballasted to nominal depth of 700 and 2000 m and tracked for 15 months have been analyzed to produce synoptic and statistical descriptions of the Gulf Stream and subtropical gyre. SOFAR ...
Topographic Preconditioning of Open-Ocean Deep Convection
Publisher: American Meteorological Society
Abstract: Evidence for oceanic convection over Maud Rise in the Weddell Sea suggests that bottom topography may select the location and scale of deep convecting oceanic chimneys forced by seasonal large-scale atmospheric cooling. ...
Observations of the Horizontal Interactions between the Internal Wave Field and the Mesoscale Flow
Publisher: American Meteorological Society
Abstract: Momentum and energy transfers from the mesoscale horizontal velocity shear to the internal wave field have been deduced from an analysis of a closely spaced, 25 km, moored current-meter array. The correlation between the ...
Observed and Numerically Simulated Kinetic Energies for MODE Eddies
Publisher: American Meteorological Society
Abstract: It is demonstrated that the outcome of an intercomparison between data and the vertical distribution of eddy kinetic energy predicted by a previously developed numerical model of the MODE area is frequency dependent. In ...
Deep Currents in the Central Subarctic Pacific Ocean
Publisher: American Meteorological Society
Abstract: Sections of closely spaced CTD stations along Longs. 165°W, 175°W and 175°E, in combination with 14-month current records from the central longitude, define two deep, nearly zonal currants, with speed increasing upward, ...
A New Algorithm for CTD Oxygen Calibration
Publisher: American Meteorological Society
Abstract: An algorithm for converting the Beckman dissolved-oxygen probe variables with other data from a WHOI/Brown CTD/O2 system to oxygen concentration is presented. Improvements over earlier oxygen algorithms are inclusion of ...
Anomalous Anomalies in Averaged Hydrographic Data
Publisher: American Meteorological Society
Abstract: A comparison of a recently assembled hydrographic database for the North Atlantic with the Lovitus atlas shows striking differences in the vicinity of the Gulf Stream and the North Atlantic Current. On isopycnal surfaces ...
Horizontal Scales of Variability over the Middle Atlantic Bight Shelf Break and Continental Rise from Finescale Observations
Publisher: American Meteorological Society
Abstract: bservations with fine horizontal resolution are used to identify the horizontal scales of variability over the Middle Atlantic Bight (MAB) shelf break and continental rise. Spray gliders collected observations along two ...
