Abstract
TO the oceanographer the eastern part of the Malay Archipelago is one of the most interesting regions of the world. The Challenger, Gazelle, Siboga and Planet showed that it consists of a number of enclosed seas, often of great depth, which are separated from one another or from the surrounding oceans by much “shallower sills. They are filled from sill level downwards with the densest water which can gain access to them, the water at the depth of the sill. Thus the Sulu Sea has a temperature of more than 10° C. from 400 m. to the bottom in 4,400 m. The oceanography of such a region must depend to a very large extent on the contours of the bottom, but no detailed survey was possible until the invention of the echo sounding gear.
