This is a combined tracer injection and HRP experiment, being conducted at about 12N, 54W, in an region of thermohaline staircase features prevalent in the depth range of 200 - 450 meters. The goal of this experiment is to quantify the intensity of vertical mixing in a thermohaline staricase. To do this, XBTs were used to map the extent and levels of the staircases, which then guided selection of a suitable location to inject the tracer. The tracer injection runs were done at night and HRP dives were done during the day. Once the injections were completed, five days of continuous HRP profiling tracked the patch of water containing the tracer. Sampling of the tracer patch interspersed with HRP profiles constituted the activity until the end of the cruise.
