During the 1980's, the Commission published the Geological Atlas of the World, which included the maps of the 5 oceans of the globe. Two decades have elapsed and the knowledge of the sea-floor experienced very significant progress; therefore some 5 years ago, the Commission decided to launch a new type of ocean mapping. The Structural Map of the Indian Ocean is the first of this new series of maps.展开更多
