Scientists North Atlantic Ocean currents New England coast sea level
2019/10/28
A new study by NSF-funded scientists at the Woods Hole Oceanographic Institution clarifies the influence of major currents in the North Atlantic Ocean on sea level along the coast of the northeastern ...
Shipboard Deployment of a VHF OSCR System for Measuring Offshore Currents
Shipboard Deploymen VHF OSCR System Measuring Offshore Currents
2015/8/10
In July 1994, an OSCR unit was deployed aboard the R/V Columbus Iselin to explore the feasibility of obtaining offshore, vector surface currents from a single platform. The concept is straightforward....
Frictional Currents in the Mixed Layer at the Sea Surface
Frictional Currents Mixed Layer Sea Surface
2009/4/3
The wind-driven flow in the mixed layer between the free surface and the top stable sheet of a thermocline is usually turbulent. The frictional component of such a flow may be separated from a depth-i...
Interactions between Steady Won-Uniform Currents and Gravity Waves with Applications for Current Measurements
Interactions Gravity Waves Steady Won-Uniform Currents Current Measurements
2009/4/3
Interactions between steady non-uniform currents and gravity waves are generalized to include the case of a random gravity wave field. The Kitaigorodskii-Pierson-Moskowitz frequency spectrum is used a...
Theoretical Aspects of Wind-Driven Currents in a Sea or Lake of Variable Depth with No Horizontal Mixing
Wind-Driven Currents Variable Depth with No Horizontal Mixing
2009/4/3
Steady-state wind-driven circulations in a basin of variable depth, with only vertical turbulent mixing, are considered. The geostrophic flow away from the coast is determined for an arbitrary bottom ...
Surface Currents off Oregon as Determined from Drift Bottle Returns
Surface Currents Drift Bottle Returns Determined
2009/4/3
It is generally known that surface currents off Oregon flow equatorward in summer when winds are from the northwest and poleward in the winter when winds are from the south. A detailed pattern of surf...
Wind Effects on Currents Observed in Juan de Fuca Submarine Canyon
Wind Effects Juan de Fuca Submarine Canyon Currents Observed
2009/4/3
Juan de Fuca submarine canyon has depths exceeding 200 m extending completely across the continental shelf. Observations of currents in the canyon during winter 1970 showed relatively large currents a...
An Ekman Model of Coastal Currents in a Lake or Shallow Sea
Ekman Model Coastal Currents Shallow Sea
2009/4/2
Coastal currents are investigated by use of asymptotic solutions in a steady-state barotropic lake or shallow sea of variable depth, with only vertical eddy viscosity and zero Rossby number. Earlier w...
Continental Shelf Waves：Low-Frequency Variations in Sea Level and Currents Over the Oregon Continental Shelf
Continental Shelf Waves Sea Level Low-Frequency Variations Oregon Continental Shelf
2009/4/2
Sea level variations and currents on the Oregon continental shelf exhibit wavelike characteristics in a frequency band from approximately 0.15 to 0.45 cycle per day (cpd). Shelf wave dispersion curves...
Observed Anisotropy of Spectral Characteristics of Internal Waves Induced by Low-Frequency Currents
Spectral Characteristics Internal Waves Low-Frequency Currents
2009/3/26
The isotropy of the internal wave field is investigated from short-time spectra of horizontal current measured in the deep sea. A significant anisotropy is detected at high frequencies during most per...
Some Characteristics of Nearshore Currents along the North Shore of Lake Ontario
Nearshore Currents North Shore of Lake Ontario
2009/3/26
In three periods during 1970 representative of spring, summer and fall, the horizontal currents off Oshawa in Lake Ontario were measured at distances of 3, 6, 11 and 16 km offshore. All records were s...
Two time-dependent “vertical cross section models” are analyzed and applied to wind-driven currents in Lake Ontario. The models are: 1) a linear frictionless, two-level model, and 2) a numerical model...

2009/3/26
The mean meridional profile of dynamic topography across the zonal currents of the equatorial Pacific Ocean is disturbed by the observed deviation of monthly sea level at island stations from the long...
We study below with the aid of linearized equations, but using a quadratic bottom friction law, the barotropic forced (aperiodic) response to wind stress or external pressure gradient of various simpl...

2009/3/26
A simple, two-layer, quasi-geostrophic model is used to investigate the stability of baroclinic currents confined to a finite length scale L in a basin of considerably larger dimension (4L). The curre...
