The objectives of the Gulf of Cadiz Expedition were to observe the vortices shed in the wake of Ampere Seamount, to survey Meddies formed by the Mediterranean outflow near Cape St. Vincent, Portugal, and to study the structure and dynamics of the outflow plume west of the Strait of Gibraltar. During the Expedition (September 4-28, 1988), velocity, hydrographic, and dissipation measurements were made using a variety of instrument systems (XCP, ...
Velocity profiles collected with an expendable current profiler (XCP) and with a recoverable free fall profiler, TOPS(Total Ocean Profiling System), are compared in the vicinity of the geographic and geomagnetic equators. The XCP operates on the principles of motional induction, measuring the electric currents that result from the movement of seawater through the vertical component of the earth's magnetic field. Induced electric currents that results from the movement of seawater ...
