USE OF VOLCANOES FOR DETERMINATION OF DIRECTION OF LITTORAL DRIFT

Per Bruun, Gisli Viggosson

Abstract


The title of this paper may sound like a ;joke Correctly the title ought to be "Determination of Direction of Littoral Drift on the South Coast of Iceland by Geomorphological Approach" In order to check the results of such study based on the movements of river entrances and their geometry the use of an accelerometer buoy to be placed in offshore open waters for collection of wave data combined with the results of meteorological data was discussed Then the volcano Surtsey suddenly emerged from 400 ft depth (Nov 1964) and its huge outpours of volcanic material built up an "offshore pole station", where the shoreline development provided some information which supported conclusions from the shoreline study on the mainland Computation of wave energy input provided further information.
