Rapid Variability in the Japan/East Sea: Basin Oscillations, Internal Tides, and Near-Inertial Oscillations
Basin Oscillations Internal Tides
2015/7/24
Many processes contribute to the variations of currents, sea surface height (SSH), and thermocline depth in marginal seas. Energetic examples range broadly over time scales from slow mesoscale and int...
Tidal and Sub-inertial Fluctuations in the Florida Current
Sub-inertial Fluctuations Florida Current
2009/3/26
A 50-day time series was obtained from a current meter mooring in the Florida Current off Miami. The results agree with earlier observations regarding the significance of several-day oscillations in t...
On the Detection of “Inertial” Waves with Pycnocline Followers
“Inertial” Waves Pycnocline Followers
2009/3/9
The vertical displacements associated with oscillations near the local inertial frequency f, in a stratified ocean, are found to be significant, even very close to f. For a frequency, ω=(1+)f, the rat...
Observations on the Vertical Polarization and Energy Flux of Near-Inertial Waves
Vertical Polarization Energy Flux Near-Inertial Waves
2009/3/7
Vertical profiles of horizontal ocean currents are used to study the vertical structure and temporal behavior of internal waves in the ocean, particularly those near the local inertial frequency. The ...
An Analysis of Inertial Oscillations Observed Wear Oregon Coast
Inertial Oscillations Wear Oregon Coast
2009/3/7
Nearly two months of current meter data taken during the summer of 1973 at eleven depths at a station off the coast of Oregon in 100 m of water have been analyzed. The spectra show an 8% increase in t...
Inertial Current in Lake Ontario, Winter 1972–73 (IFYGL)
Inertial Current Winter 1972–73 Lake Ontario
2009/2/23
Nearly four months of continuous current and temperature data, taking during the 1972–73 winter depths of about 15 and 75 m in Lake Ontario, have been analyzed for evidence of inertial oscillations. T...
Wind-Driven Inertial Currents in the Magdalen Shallows, Gulf of St. Lawrence
Wind-Driven Inertial Currents Magdalen Shallows
2009/2/23
Power spectrum analyses of the residual current components from the Magdalen Shallows (autumn 1970) gave a prominent peak at the inertial frequency. Bandpass filtering showed that the inertial oscilla...
A nonlinear inertial model of a steady-state coastal upwelling circulation is presented. The model describes a longshore equatorward current and countercurrent structure which is independent of any pa...
Internal Wave Spectra at the Buoyant and Inertial Frequencies
Internal Wave Spectra Buoyant Inertial Frequencies
2009/2/19
Spectra of the vertical displacement (potential energy) have been observed to be only slightly enhanced at the buoyancy frequency ω = N, whereas spectra of horizontal velocity u, v (kinetic energy) ar...
Boundary Layer under Near-Inertial Internal Waves over a Critically Sloping Bottom
Boundary Layer Critically Sloping Bottom Near-Inertial Internal Waves
2009/2/18
Internal waves reflecting off sloping bottoms have been shown to have boundary-layer scales proportional to ν½ (ν is viscosity). As the characteristic slope of the wave approaches the slope of ...
A Study of Oceanic Boundary-Layer Characteristics Including Inertial Oscillation at Three Drifting Stations In the Arctic Ocean
Oceanic Boundary-Layer Characteristics Inertial Oscillation Three Drifting Stations the Arctic Ocean
2009/2/16
Measurements of surface drift and near-surface currents taken during August 1975, at drifting ice stations of the AIDJEX experiment in the central Arctic, are used to infer the response of the upper o...
Inertial oscillations in current records in the top 100 m of the ocean collected on three moorings 50 and 70 km apart are examined. At 12 and 32 m depth the records are horizontally coherent at inerti...
Topographically Induced Changes in the Structure of an Inertial Coastal Jet：Application to the Agulhas Current
Inertial Coastal Jet Agulhas Current
2009/2/13
Calculations are made of the changes in the structure of an inertial current which can be induced by slow changes in the topography of the continental shelf and slope along which it flows. The particu...
An Experimental Study of Gravity-Inertial Waves and Wind-Induced Kelvin-Type Upwellings in a Rotating System
Gravity-Inertial Waves Rotating System Wind-Induced Kelvin-Type Upwellings
2009/2/10
Large-amplitude gravity-inertial waves have been observed in stratified seas. These waves, of a shorter period than the Coriolis period, are linked to a gust of wind. Numerous theories have been propo...
Inertial Oscillations on the Continental Shelf of the Gulf of Lions—Observations and Theory
Inertial Oscillations Lions—Observations Continental Shelf
2009/2/9
Observations in the Gulf of Lions (northwestern Mediterranean Sea) in summer have shown that gusts of wind lasting a few days generate transient upwellings and inertial motions. Oscillations at the in...
