What would the criteria be to volunteer for Antarctica? Would branch be able to help out with that?

I worked in Antarctica for seven seasons, 35 months, on the 'ice' working out of McMurdo. I proudly wear the Antarctic Service Medal that I earned as a civilian on my military uniform. Unless you are assigned to Operation Deep Freeze, are in the US Coast Guard or fly C-17's with the Air Force or C-130's with the 109th Air National Guard, it is hard to go down in a military capacity. As a civilian you could work for one of the civilian contractors there, or go down as a researcher affiliated with a university or project. The ASM is one of the few medals that is awarded to civilians. I hope I will one day be given the opportunity to work in the Arctic so that I can earn the Arctic Service medal and be 'bi-polar', but the odds of that are very slim.

Even if it’s a definite NO, I still wanna know. I think it would be cool for 1 month or how ever long it is. Overall I want it for the Antarctica service medal. To be honest.

If memory serves there are Army and USAF units that support the mission. The Army unit was the the Trans Gp at Ft Lee. Aside from that, you might get a TDY gig as a researcher or research support. The National Science Foundation runs the US facilities in Antarctica.
