Structure and Transport of the Antarctic Circumpolar Current at Drake Passage from Short-Term Measurements
Antarctic Circumpolar Current Short-Term Measurements Drake Passage
2009/3/7
Three-week average speeds from an array of current meter moorings which spanned Drake Passage were used in conjunction with geostrophic calculations to estimate the short-term transport of the Antarct...
A Cyclonic Eddy in the Antarctic Circumpolar Current South of Australia：Results of Soviet-American Observations Aboard the R/V Professor Zubov
Cyclonic Eddy R/V Professor Zubov Antarctic Circumpolar Current
2009/2/23
Hydrographic, expendable bathythermograph and 16-day current meter records are combined to describe the oceanic structure south of Australia (along 132°E) between 24 January and 1 March 1977. A strong...
On the Estimation of Absolute Geostrophic Volume Transport Applied to the Antarctic Circumpolar Current
Absolute Geostrophic Volume Transport Antarctic Circumpolar Current
2009/2/13
An objective method of estimating the geostrophic barotropic volume transport across an oceanographic section is developed and applied to the transport of the Antarctic Circumpolar Current through the...
The Dynamics of Large-Scale, Wind-Driven Variations in the Antarctic Circumpolar Current
Large-Scale Antarctic Circumpolar Current Wind-Driven Variations
2009/2/8
A nonlinear model is developed and analytical results obtained to discuss the response of the Antarctic Circumpolar Current to wind forcing over a wide range of frequencies. The main results are as fo...
The Net Transport of the Antarctic Circumpolar Current through Drake Passage
Net Transport Drake Passage Antarctic Circumpolar Current
2009/2/8
Estimates of the net transport through Drake Passage are made for three periods during which the year-long DRAKE 79 current meter array spanning the Passage was in operation. Relative geostrophic shea...
Monitoring the Transport of the Antarctic Circumpolar Current at Drake Passage
Antarctic Circumpolar Current Drake Passage
2009/2/6
Data from an extensive moored instrument array and three hydrographic cruises are used to calculate a time series of the net transport through the upper 2500 m of the Drake Passage. The baroclinic geo...
The interaction between a close wind-gyre and a neighboring eastward current is investigated using a hierarchy of increasingly complex analytical models. The method used to determine the vertical stru...
Topographic Influences on Wind-Driven, Stratified Flow in a β-Plane Channel：An Idealized Model for the Antarctic Circumpolar Current
Topographic Influences Wind-Driven Stratified Flow β-Plane Channel Antarctic Circumpolar Current
2008/12/27
Topographic influences are examined in an eddy-resolving model of oceanic channel flow forced by steady zonal winds. With small explicit lateral friction, transient eddies generated by the baroclinic ...
Vorticity Dynamics of Seasonal Variations of the Antarctic Circumpolar Current from a Modeling Study
Antarctic Circumpolar Current Seasonal Variations
2008/12/24
A one-layer numerical model was developed to analyze the vorticity dynamics of the seasonal variations of currents in the Southern Ocean. The model includes the continental geometry and bathymetry of ...
Wind-Driven Flow over Topography in a Zonal β-Plane Channel：A Quasi-geostrophic Model of the Antarctic Circumpolar Current
Circumpolar Current Wind-Driven Flow Zonal β-Plane Channel Antarctic Circumpolar Current
2008/12/23
The paper gives a detailed account of the dynamical balance of a wind-driven zonally unbounded flow over topography. The problem is investigated with a quasi-geostrophic β-plane channel with two layer...
