Absolute geostrophic currents in the East Auckland Current region

New Zealand Journal of Marine and Freshwater Research, 2002
Abstract Absolute geostrophic currents are estimated for the full depth of the water column off the north‐east coast of New Zealand for February 1998. This is achieved by objectively‐mapping subsurface Acoustic Doppler Current Profiler (ADCP) data using horizontal length scales determined from repeat high‐resolution Expendable Bathythermograph (XBT ...

Absolute geostrophic currents in global tropical oceans

Chinese Journal of Oceanology and Limnology, 2016
A set of absolute geostrophic current (AGC) data for the period January 2004 to December 2012 are calculated using the P-vector method based on monthly gridded Argo profiles in the world tropical oceans. The AGCs agree well with altimeter geostrophic currents, Ocean Surface Current Analysis-Real time currents, and moored current-meter measurements at ...

Shaping of the Continental Rise by Deep Geostrophic Contour Currents

Science, 1966
Geostrophic contour-following bottom currents involved in the deep thermohaline circulation of the world ocean appear to be the principal agents which control the shape of the continental rise and other sediment bodies.

The boundary currents east and north of Madagascar: 1. Geostrophic currents and transports

Journal of Geophysical Research: Oceans, 1988
Geostrophic currents and transports in the boundary currents near Madagascar are described for a section at 23°S off the east coast and at 12°S to the northeast of Cape Amber. These results are based on conductivity‐temperature‐depth and expendable bathythermograph sections made during cruises of the Marion Dufresne in 1984, 1985, and 1986 ...

Estimates of Geostrophic Surface Currents in the South Atlantic Bight

Marine Geodesy, 2009
The determination of long-term trends in the behavior of the Gulf Stream is critical to understanding the meridional heat transfer cycle and associated global climate change. In this study, in situ current measurements from cross-stream transects of an Acoustic Doppler Current Profiler (ADCP) were used in conjunction with satellite altimetry data to ...

Geostrophic currents in shelf areas

Continental Shelf Research, 1986
Abstract A method for obtaining geostrophic currents in a stratified ocean is discussed. It combines the use of hydrographic data and numerical modelling. For geostrophic flow in a flatbottom stratified ocean it is shown along the lines of Gill and Clarke (1974 , Deep-Sea Research , 21 , 325–345) that the surface elevation is determined by the

Monitoring geostrophic currents at the equator

Deep Sea Research Part A. Oceanographic Research Papers, 1987
Abstract A single intensively sampled (1 km station spacing) density section across the equator from 3°N to 3°S at 140°N15′W was made in November 1984. The close station spacing allowed us to consider the effects of internal wave aliasing and to filter these out of dynamic height computations.

Mode-one internal tides propagating across a geostrophic current

Physics of Fluids, 2021
As a mode-1 internal tide (IT) propagates across a geostrophic current V(x, z), we have investigated the amount of IT energy reflected from the current and the impact of the current on the transmitted wave field. These are quantified by considering the reflection coefficient R and the linear modal energy conversion Pn, where n is the modal number. Here,

Ageostrophic, anticyclonic instability of a geostrophic, barotropic boundary current

Physics of Fluids, 2004
After having previously demonstrated the occurrence of ageostrophic, anticyclonic instability (AAI) for several other steady flows, in this paper we further test the hypothesis that rotating, stably stratified, shear flows are generally subject to AAI at finite Rossby (Ro) and Froude (Fr) numbers by calculating the inviscid, incompressible normal modes
