Other than diving just for the fun of it - recreational diving, there are other types of diving that people partake in. Here's a look at some of them.
Technical diving
This is any dive that goes deeper than 30 meters in which the diver lacks direct access to an open water surface. This can be in a cave or under the ice. Here are some examples of technical diving.
Deep diving
In recreational diving, a depth of 30 metres is counted as deep diving, for technical diving it's 60 metres, and in surface supplied diving, anything below 100m is regarded as a deep dive. Surface supplied diving is where the diver is supplied with air through a tube coming from the surface.
Wreck diving
This involves diving down to wrecked ships or other craft underwater. Other than the interest of the site itself, wrecks often result in good habitats for marine life, almost like an artificial reef. Wreck diving should be never done alone.
Archaeological diving
Undersea sites can offer tremendous archaeological finds. This can include wrecks and 'lost cities'. For example, diving in the Black Sea can reveal villages that have been submerged in recent millennia.
Cave diving
This is very challenging both physically and psychologically and you need to be an expert diver to try it. For example, you can easily become disoriented in a dark, underwater cave.
Ice diving
The challenge here of course is the low temperature. There are also other risks such as being trapped under the ice. For these reasons, the ice diver is usually attached to the surface by a line. This allows the diver to be pulled out if he gets disabled by cold or loses his way under the ice.
