Cruise report : Oceanus 250 Leg 4 High Resolution Profiler survey for the North Atlantic Tracer Release Experiment: (NATRE), March 25-April 24, 1992

Abstract

This report describes fine- and microstructure profile data taken on R/V Oceanus cruise 250 leg 4, between March 25 and April 24, 1992. During this cruise, an area of the Canary Basin near the Subduction Experiment's central mooring was surveyed with the High Resolution Profiler (HRP). The goals of the survey were to describe the hydrographic properties of the water adequately to recommend a location for the North Atlantic Tracer Release Experiment (NATRE) tracer injection, and to characterize the microstructure for comparison with the NATRE results. The work performed at sea, instrumentation, data return and processing procedures will be summarized in this report.
