UAVs stands for Unmanned Aerial Vehicles. The British Antarctic Survey has successfully completed a series of flights with these robotic airplanes. So far they have been flown over 20 flights lasting around 40 minutes each. The planes make measurements "about the exchange of heat between the lower atmosphere and sea ice." The planes basically look like large model airplanes (see a photo of one along with the original article here). It is interesting how this technology is harder to operate in the Antarctic, but overall easier to operate here than some other locales because safety wise there is not much to run into.
