# MLD Analysis
# DISCUSSION: I decided to calculate MLD from both a temperature threshold and a density threshold. From my observations, the MLD_T is a much better indication of the near surface mixed layer present in my region. I wanted to retain the MLD_D though, as sigma*0.125 is derived from the subtropical mode water of the North Atlantic (Levitus 1982). I figured this value could be useful for analyzing changes in the intruding Atlantic water as any value below MLD_D should be water primarily from this source.
# I should note, MLD_D is not available for about half of the profiles (154/310). This is not a bug, the reason is that there is no value at which pden == pden[1]*1.125 for these profiles. This could be a finding as well, as I think that it means that Atlantic water is not present, or at least not significantly strong in the region. This could also indicate that the profiles are very shallow. I intend to plot these unique profiles on a map to find correlation. As the MLD_D is incomplete and not indicative of the near surface mixed layer in my region, I will only be plotting MLD property trends from MLD_T data.
# UPDATE TO DISCUSSION: I find no obvious visual correlation in the spatial distribution or the depth distribution for the casts with no MLD_D value. Perhaps this is just a bad definition for MLD in my region. Or perhaps the water in region is not prominently from the subtropical mode water.
