Heat flow
The Ross Sea region experiences elevated heat flow, consistent with a rift setting. The average heat flow over the Ross Sea region is probably close to 70 mW/m2, with a high standard deviation. Near the active volcano Mount Erebus, heat flow has been measured as high as 164 mW/m2. Results are shown in Figure 21.
