Hydrographic data from R/V Endeavor cruise #143

Abstract

Hydrographic data collected during R/V Endeavor cruise 143 is presented as a preliminary study of subduction in the northeast Atlantic south of the Azores Front. The front is clearly defined at the northern end of CTD section #1 which also shows a layer of 16-18°C water subducted to the south. Section #2, 280 km to the east, is dominated by a large cyclonic ring with characteristics similar to 'eastern' rings reported earlier . An anomalously salty parcel of Mediterranean water in this section is typical of highly saline lenses seen in the Canary Basin.
