The Great Rift Valley is a huge gash cut into East Africa, extending 3000 kilometers from Malawi in southern Africa to the Red Sea in the north. Beneath the Great Rift Valley, the next new ocean on Earth may be forming. This radio broadcast ptovides interviews with geologists who are studying this part of Africa to learn how new seas appear. The tectonic plates that form the continents drift continuously about the globe as new oceans open up and old ones get closed down. But, occasionally, continents themselves split apart and new ocean floor forms from volcanoes that erupt in the the ensuing rift. It is this event that geologists believe they are witnessing in East Africa. The broadcast discusses Project EAGLE (Ethiopia Afar Geoscientific Lithospheric Experiment), an investigation into how a continental rift turns into a new ocean. The broadcast is 30 minutes in length.
