Lesson 30-1     Exploring the sea-floor

Our knowledge ofthe oceans a hundred years ago was confined to the two- dimensional shape ofthe sea surface and the hazards of navigation presented by the irregularitiesin depth of the shallow water close to the land. The open sea was deep andmysterious, and anyone who gave more than a passing thought to the bottomconfines of the oceans probably assumed that the sea bed was flat. Sir James Clark Ross had obtained a sounding of over2,400 fathoms in 1839, but it was not until 1869, when H.M.S Porcupine was putat the disposal of the Royal Society for several cruises that a series of deepsoundings was obtained in the Atlantic and the first samples were collected bydredging the bottom. Shortly after this the famous H. M. S. Challengerexpedition established the study of the sea-floor as a subject worthy of themost qualified physicists and geologists.
