Oceanography has been defined the application of all 【S1】______
sciences to the study of the sea. Before the nineteenth century,
scientists with an interest in the sea were few or far between, 【S2】______
Certainly Newton considered some theoretical aspects of it in his
writings, but he was unwilling to go to sea to farther his work. For 【S3】______
most people the sea was remote, and with the except of early 【S4】______
intercontinental travelers or others who earned a living from the
sea, there was little reason to ask many questions about it, to let 【S5】______
alone ask what lied beneath the surface. The first time that the 【S6】______
question "What is at the bottom of the oceans?" had to be
answered with any commercial consequence was the laying of a 【S7】______
telegraph cable from Europe to America was proposed. The
engineers had to know the depth profile of the route to estimate
the length of cable that had to be manufactured. It was into Maury
of the US Navy that the Atlantic Telegraph Company turned, in 【S8】______
1853, for information on this matter. In the 1840s, Maury had
been responsible for encouraging voyages during which
soundings were taken to investigate the width of the North
Atlantic. Later, some of his findings aroused much popular 【S9】______
interests in his book The Physical Geography of the Sea. 【S10】______
