Fig. 3. (A) Example data trace of temperature measurements from one experiment. Probes 1–3 were placed at the interface between the heat source and the standard material, probes 4–6 were placed between the standard material and the deep blubber surface, and probes 7–9 were placed at the interface between the epidermis and air (see Fig. 2). (B) Example data trace of heat flux values from the deep and superficial heat flux discs from the same experiment. For both traces, only data from the final 30 min of the experiment were used in the thermal calculations.
