High resolution profiler study of deep mixing in the Romanche fracture zone
Between November 20 and December 10, 1994, studies of the deep mixing processes in the Romanche Fracture Zone (RFZ) of the Mid-Atlantic Ridge were conducted from the French research vessel N/O le Noroit. Oceanographers from France and the U.S. worked together to acquire the unique data obtained on t...
