Larry Anderson, Jim Ledwell and Dennis McGillicuddy, WHOI
In January 2001, J. Ledwell and colleagues released 175 kg of the inert
tracer SF6 in the 10oC
step of the thermohaline staircase east of Barbados near 13oN
54oW to study mixing in the staircase region.
The mean depth of this step was approximately 380 meters. D. McGillicuddy
and L. Anderson performed the same experiment in their 0.1o-resolution
primitive equation model of the North Atlantic for 1993 for comparison.
