What really happens to the human body—and the environment—when you dive past 200 feet? At this depth, everything changes. Light fades, pressure increases dramatically, and the risks become very real.

This means that the pressure in a fluid changes depending on its height, depth and temperature. The particles in a gas move quickly in random directions. Therefore the particles regularly bump ...

Density in particular is an important property in ocean science because small spatial changes in density result in spatial variations in pressure at a given depth, which in turn drive the ocean ...
