SCUBA descent and ascent rates: what is the descent rate?

Explanation:
Descent rate is simply how fast you descend from the surface to deeper depths. A controlled descent lets you equalize your ears, monitor your gear, and avoid rapid pressure changes that can cause barotrauma or loss of orientation. The option describing a descent rate of 75 feet of seawater per minute matches the concept of a steady, down-ward pace used in training. The other numbers describe ascent rates, which relate to rising toward the surface rather than going down. So, the descent rate best described here is 75 fsw/min.
