Any time you scuba dive at an altitude higher than 300 metres/1000 feet above sea level, you’re altitude diving.

How deep can you dive and not get the bends?
At depths greater than 40 metres (130 ft), a diver may have only a few minutes at the deepest part of the dive before decompression stops are needed. In the event of an emergency, the diver cannot make an immediate ascent to the surface without risking decompression sickness.
How are the depth of a dive and altitude related?
Essentially, the higher the altitude, the greater the change in pressure through the first 30 feet of depth underwater because the ambient air pressure is less at altitude than it is at sea level and it decreases as you move higher. To compensate, adjust your dive plan.
