Abstract

The obvious question to ask about the sea floor is how deep it is and why. The overall depth distribution first became known through the voyage of H. M. S. Challenger (Fig. 1.1). We see that there are two most common depths: a shallow one near sea level (shelf seas), and a deep one between 1 and 5 km (normal deep ocean). The sea floor connecting shelves and deep ocean is of intermediate depths and makes up the continental slopes and rises. There is a portion of sea floor which is twice as deep as normal: such depths occur only in narrow trenches, mainly in a ring around the Pacific Ocean (Table 2.1).
