Figure 3 - Annual cycles of SST and turbulence at 0, 140 W. SST (black), subsurface turbulent heat flux < Jq>20-60m
(blue) and the part of the surface heat flux that contributes to mixed layer heating (Jq0- Ih)
(red). Natural variability is represented by 95% bootstrap confidence intervals on 15-minute averages of Jq
for the largest (August) value by the adjacent blue bar, and for all of the data by the blue bar adjacent to the December value (adapted from Moum et al., 2013).
