Abstract: In September?October 1988 and in April 1989 two 4-week cruises were organized to study the structure and dynamics of Gulf Stream meanders. The first one focused on an anticyclonic crest, and the second one on a cyclonic ...

Abstract: Between September 1980 and May 1983, 16 sections of temperature and velocity were obtained with the Pegasus instrument along a transect crossing the Gulf Stream at 73°W. The mean temperature and velocity fields of the upper ...

Abstract: An overview of the first 4.5 years of operation of a program to monitor the structure and variability of the Gulf Stream (GS) is presented. A container vessel that operates on a weekly schedule between Port Elizabeth, New ...

Abstract: The spatial distribution of static stability in the Gulf Stream was studied using cross-and downstream XBT sections taken between Cape Hatteras and 70°W. The cross-stream sections revealed large variations in static ...

Abstract: Historical hydrographic sections are used to investigate the seasonal and interannual variability in the meridional heat flux at 36°N in the North Atlantic. The data consist of ten transatlantic sections and sections from ...

Abstract: The terms in the Lagrangian potential vorticity equation are estimated by three different methods using clusters of SOFAR floats in the main (700 m) and lower (1300 m) thermocline of the POLYMODE region. The Lagrangian ...

Abstract: A unique set of Lagrangian observations has recently been collected in the Gulf Stream using the newly developed isopycnal RAFOS float. Between January, 1984 and October, 1985, thirty-seven of these drifters were launched ...

Abstract: Two surveys of the absolute velocity field of an eddy of Mediterranean Water (meddy) in the Eastern North Atlantic were conducted one year apart in 1984 and 1985. Two velocity regimes were revealed. Within the radius of ...

Abstract: POGO is a simple technique for measuring water transport between the surface and some preselected depth. Equipped with a 12-kHz pinger for tracking and range measurement, a xenon flasher for nighttime relocation, and a VHF ...

Abstract: The RAFOS float is a small neutrally buoyant subsurface order, which, like its big brother the SOFAR float, uses the deep sound (or SOFAR) channel to determine its position as a function of time. Whereas the SOFAR float ...
