WebIn the ocean, for every 10 meters of depth, the pressure increases by nearly 1 atmosphere! Imagine the pressure at 10,000 meters; that would be 1,000 kilograms per square centimeter (14,700 lbs/sq in). Today’s submarines usually dive to only about 500 meters; to go deeper than this they must be specially designed for greater depth (Figure 14.20). WebTo map the ocean floor we need to know the depth at a number of places. The process of measuring the depths is known as. bathymetry. . These measurements were first made through. soundings. , where a weighted line (lead line) was let out by hand until it touched the bottom, and the depth could be recorded from the length of the line (Figure 1.4.1).
