FIGURE 6 | Comparisons of temperature and salinity from the profiler and hydrographic data on three different days on (A) August 29, 2016, which is 25 days, (B) November 24, 2016, 112 days, and (C) January 24, 2017, 173 days after the first deployment. The dashed line is for the profiler and the solid one for the hydrographic observations. The numbers in the figure represent the difference between the two within upper mixed layer in each case. The time difference between the profiler and the hydrographic cast is less than 1.5 h in all three.
