Sure... I work on experiments where we basically we instrument ice sheets with radio antennas and look for radio emission that might come from really energetic particles smashing into the ice. One of the experiments I work on (the Askaryan Radio Array) is at the South Pole. Each detector has a single board computer to take data and such. They are cabled via fiber to the IceCube lab at Pole, where data is relayed to. About half the time, the South Pole has internet either via NASA satellites or DSCS (there is also Iridium all the time, but that is not for general use), and via some jump hosts, I can ssh into the detectors.
