To dive on an Antarctica Dive expedition you need to have 30 dives in a dry suit. More importantly you need to be completely comfortable in your dry suit and BCD. You also need to do a couple of training dives where you simulate the turning on and off your cylinder valve. You’ll need to be able to turn off your buddy’s valve if his second stage free flows. When we dive in Antarctica, we use H valves, with two regulators for this very reason. Any intermediate cold water sport diver would be able to Scuba Dive in Antarctica.
