Exploring the Bed of the Ocean

Abstract

THE earth has, for very good reasons, been called the water planets About 140 million square miles, or more than 70 per cent of the globe, are covered with water, and more than 90 million square miles of water has a depth exceeding 2,000 fathoms. No part of the eath's solid crust is less accessible to scientific investigations than the floor of the ocean. No part, on June other hand, offers a greater variety of unsolved problems. In our days, when both the north ane the south poles have been reached, the deserts.of central Asia, the primeval forests of Africa and of South America, and the barren ice-fields of Greenland and the antarctic continent have been explored, the last remaining white area on the world map is the ocean floor.
