A diver descends 20 meters below sea level, then ascends 8 meters, dives again to double the depth of the second dive, and finally ascends 15 meters. What is the divers final depth relative to sea level?

**What Is the Diver’s Final Depth After This Complex Descent?** Dive deeper into the numbers behind one of the most attention-grabbing underwater sequences — where a diver descends 20 meters below sea level, ascends 8 meters, dives again deeper—this time doubling the depth of the second dive—then ascends 15 meters. Curious observers and water safety advocates alike are asking: what’s the diver’s final position beneath the surface? What’s truly happening here is a precise series of vertical movements beneath the ocean, combining depth, ascent, and calculated increases. The diver starts at 20 meters down, moves up 8 meters—to 12 meters below sea level—then dives again, plunging to double that second depth of 8 meters, which is 16 meters below. After ascending 15 meters, the diver emerges to a final depth that reveals how delicate and dynamic underwater navigation really is. This sequence, while seemingly simple, illustrates key principles of depth measurement and vertical displacement in diving. Understanding the final depth helps clarify not only the diver’s position but also oceanic pressure dynamics, safety margins, and training protocols. It’s a query people are increasingly asking as underwater exploration trends grow in both recreation and research.
