Abstract : We look at 3 methods for estimating the regional heat flow: a simple mean of all heat flow measurements, the heat flow at the regional median depth, and the mean of gridded heat flow measurements. We find that the simple mean is the least accurate method: simple means estimate the average heat flow at the median water depth of the heat flow survey and are often significantly biased. The heat flow at the regional median depth is more accurate, but can be biased by the spatial distribution of the heat flow survey. The mean of gridded heat flow data produces the most accurate estimate of the regional heat flow. However, the value of the gridded mean is influenced by the grid spacing, and other methods of gridding should be evaluated. (MM)
