How do you go underwater in Antarctica?
Underwater research is conducted by divers wearing full wet suits and SCUBA gear. Dive tenders bore a hole in the sea ice, which is eight to 12 feet thick, and lay rubber mats around the hole. A weight on a rope is dropped to the benthos below. Flags are tied every 12 inches on the rope, so that a diver can always locate the rope that marks the dive hole. Divers fill specimen buckets with animals, stones and other material from the benthos, and the buckets are hauled up by the dive tenders. When the divers are ready to come to the surface, they return to the flagged rope and rise as fast as their bubbles. The dive tenders then help the divers out of the water.
How do scuba divers explore the underwater world through bouyancy?

It consists of a regulator, tank, buoyancy control device -harness and instruments. Dive watch - Used to measure the dive time. Dive computer - Monitors your depth and time underwater to keep you within established limits. Weight system - Offsets your tendency to float so you can descend gently underwater when you want to. Fins - Allow you to swim using only your powerful leg muscles. Dive light - Used to look into cracks and crevices, and for diving at night. Dive knife - A handy tool as well as an important safety device. Dive flag/float - Keeps boaters away from where you're diving.

for the same reason a boat floats. Upthrust which is greater than gravity. Alternatively you can just swim vertically upwards. Beware though, if you go too far down then your body will be crused by the water pressure
Why cant scuba divers go 300 feet under the water?
Nothing other than training. Technical diver do it all the time, but recreational divers are limited by either air or nitrox which is narcotic at 40 meters (131 feet) and a very short time limit where technical divers can be trained in using helium as well as how to perform decompression stops.
