The working group submitted to the Panel a proposal for the arrangement of an interdisciplinary workshop on Marine Slides and other Mass Movements, and the Panel decided to fund such a workshop. Mass movement of soils and rocks on subaerial slopes is a subject which has been intensely studied over the past fifty years, and its literature is becoming extens­ ive. The submarine phenomenon, although similar in its pbysical basis, is much less studied, but has become an important subject (particularly during the past decade) because of the increase of man's use of the coastal en­ vironment and the intensified exploration for oil and minerals on the continental margins and ocean basins.
