Description
Summary:During cruises in the Norwegian Sea in 1969 and 1972 seven heat flow values were measured between Iceland and the Vøring Plateau. The six eastern values of this profile show a positive trend eastsoutheastwards which coincides with a possible transition from oceanic to continental ernst suggested by seismic results. One heat flow value taken near Iceland and 250 miles west of the others reflects the influence of the Mid-Atlantic Ridge. An estimation of the heat flow at a depth of 15 km below the measuring localities yields values with a small, possibly insignificant negative trend towards the east-southeast. The temperatures at 15 km depth are estimated to be 190°C beneath the zone of seamounts and 280 °C beneath the Vøring Plateau.
