Objectives

This was the third and last scheduled "tracer documentation" cruise associated with the North Atlantic Tracer Release Experiment (NATRE). Its object was to study the rates of both vertical and horizontal mixing in the main pycnocline of the Northeast Atlantic subtropical gyre, using a release of sulphur hexafluoride tracer, marked by neutrally buoyant floats. The task of the present cruise was to document the distribution of the tracer one year after release.
