I have finally managed to submit this paper to JGR-Oceans. The paper represents our attempt to use passive-tracer-based methods to diagnose mixing rates globally. The basic method was developed by John, Emily Shuckburgh, Helen Jones, and Chris Hill in a 2006 paper. Here we attempt to apply this method globally to produce a map of mixing rates everywhere.
The results can be summed up by this figure, a global map of passive-tracer mixing rates.
