Antarctica 2013--2014 Part 8: Ice Tunneling

Photo of Ice Tunnels

A few weeks ago I went on a tour of the South Pole ice tunnels. These run underneath the station, connecting it to the power plant, food storage, water treatment plant, and water supply. Probably the most interesting part was understanding how the water supply works. Fresh water comes from a Rodrigues well ("rodwell"), a hole in the ice we slowly expand by melting and pumping water out of it. To do so, we have to pump in hot water. Part of the heat is excess from the power plant, but the water needs to be heated again to 120 F immediately before being pumped into the rodwell.
