Short summary

Due to a thermal insulation effect of oceanic crust, the seafloor heat flux is predicted to be low over young lithosphere (compared to other cooling models). Consequently, the amount of heat extracted from oceanic lithosphere by ventilated hydrothermal circulation is predicted to be significantly lower than previous models. About 50% of total hydrothermal power is extracted on ridge axes.
