Surface flow structure of the Gulf Stream from composite imagery and satellite-tracked drifters
Surface flow structure Gulf Stream composite imagery satellite-tracked drifters
2009/11/16
A unique set of coutemporaneous satellite-tracked drifters and five-day composite Advanced Very High Resolution Radionmeter (AVHRR) satellite imagery of the North Atlantic has been analyzed to examine...
On the Acoustic Characteristics of a Gulf Stream Cyclonic Ring
Acoustic Characteristics Gulf Stream Cyclonic Ring
2009/4/2
The acoustic properties of a cyclonic Gulf Stream ring have been studied with field data and ray computations. Cyclonic rings represent relatively low sound velocity regions with large horizontal grad...
Gulf Stream Eddies：Recent Observations in the Western Sargasso Sea
Gulf Stream Eddies Western Sargasso Sea
2009/4/2
A cyclonic Gulf Stream eddy was observed in the western Sargasso Sea by satellite infrared measurements and later confirmed by ship measurements. Fourteen months of observations indicate that the eddy...
Transient Gulf Stream Meandering. Part II：Analysis via a Quasi-Geostrophic Time-Dependent Model
Transient Gulf Stream Meandering Quasi-Geostrophic Time-Dependent Model
2009/3/26
Simultaneous path and bottom velocity measurements made during the Transient Meander Experiment, reported in Part I, are analyzed in terms of a quasi-geostrophic thin jet model of the meandering Gulf ...
Transient Gulf Stream Meandering. Part I: An Observational Experiment
Transient Gulf Stream Meandering Observational Experiment
2009/3/26
The results from an observational experiment on the mesoscale space-time variability of the Gulf Stream are reported. Various techniques, including aerial surveys, ship trackings of the 15C isotherm a...
Entrainment and Diffusion in a Gulf Stream Cyclonic Ring
Entrainment Diffusion Gulf Stream Cyclonic Ring
2009/3/24
The mixing and entrainment processes present in a cyclonic ring are investigated by means of a parametric model which is fitted to serial temperature data for a North Atlantic ring. The physical model...
A Determination of Horizontal Divergence in the Gulf Stream off Cape Lookout
Horizontal Divergence Gulf Stream off Cape Lookout
2009/3/9
A horizontal divergence of 2×10−5 sec−1 was determined by tracking three shallow drogues in the speed axis of the Gulf Stream. Concurrent bathythermograph soundings along a drogue track su...
Gulf Stream Kinematics Inferred from a Satellite-Tracked Drifter
Gulf Stream Kinematics Inferred Satellite-Tracked Drifter
2009/3/7
A drifter was deployed in the Gulf Stream and tracked for 5 months by the Nimbus 6 satellite. From this experiment we have assessed the technical capability of the satellite fixing system for measurin...
An experiment to test the feasibility of tracking Gulf Stream rings with neutrally buoyant SOFAR floats was begun in September 1974. Three floats were launched at depths of 750, 1050 and 1080 m in a r...
A Simple Topographic Model of Gulf Stream Separation
Simple Topographic Model Gulf Stream Separation
2009/3/7
A simple, frictional, linear model is used to study the motion of the Gull Stream over the continental shelf. It is found that the combination of frictional and topographic effects may provide a furth...
Distribution and Movement of Gulf Stream Rings
David Y. Lai
The distribution, number and movement of cyclonic Gulf Stream rings were estimated from an analysis of 50 000 temperature records ...
Tracking a Gulf Stream Ring with a Free Drifting Surface Buoy
Gulf Stream Ring Free Drifting Surface Buoy
2009/3/7
A newly developed buoy which is free drifting and tracked by satellite was successfully used to measure the movement of a Gull Stream ring. The buoy, launched in a young ring at 36°15′N, 58°00′W, loop...
The Application of Linear Quasigeostrophic Dynamics to Gulf Stream Rings
Linear Quasigeostrophic Dynamics Gulf Stream Rings
2009/3/7
We have used linear quasigeostrophic dynamics to calculate the motion, decay and dispersion rates of radially symmetric initial disturbances with scales appropriate to Gulf Stream Rings. Baroclinic ri...

Numerical Simulation Gulf Stream Mid-Ocean Eddies
2009/3/7
The circulation of the western North Atlantic is simulated with a primitive equation model that has 5 levels and a horizontal grid size of 37 km. The idealized model domain is a rectangular basin, 300...
Further Studies of a Cold Eddy on the Eastern Side of the Gulf Stream Using Satellite Data and Ship Data
Gulf Stream Satellite Data Cold Eddy Ship Data
2009/2/23
A cold eddy was observed in late March and early April 1975 to encounter the eastern boundary of the Gulf Stream and entrain warm Gulf Stream water into its outer fringes. Available evidence indicated...
