The Azores current system from a meridional section at 24.5°W
High spatial resolution hydrographic data, including Lowered Acoustic Doppler Current Profiler (LADCP) measurements, were acquired along a meridional section at 24.5W in October 2009. The data are analyzed in detail with the purpose of definitively defining and quantifying the zonal Azores Current S...
