| Summary: | Figure 3. Prediction surfaces of the (a) linearly approximated depth observations and estimated mean depth field of three example isotherms (8°C, 14°C, and 20°C), that were predicted using five interpolation methods: (b) 0.5° grid cell mean, (c) HYCOM reanalysis, (d) quadratic linear model, (e) objective analysis based on the quadratic linear model, and (f) generalized additive model. The color scale in each panel represents a 250 m range centered on median observed depth of each displayed isotherm, thus the relatively muted color contrast in the 20°C series of plots reflects the lower total variability in isotherm depth at this temperature level when compared with the 8°C and 14°C series of plots.
