Abstract
Data on subsurface temperature conditions from borehole measurements in various parts of Iceland were presented. The subsurface temperature field is in many areas found to be controlled by the movement of water in the upper part of the crust, and so is also the surface heat flow by conduction.
Data were presented to show that conditions for free convection of water may well exist in the neovolcanic zone of Iceland. It is suggested that this phenomenon may account for the anomalous heat flow pattern observed on the Mid-Atlantic Ridge.
