ICESat-2 Antarctic Traverse: South Pole Station: The Last Stop Before the TraverseDecember 19th, 2017 by Tom Neumann
After a few extra days in the seaside town of McMurdo Station, we flew on a ski-equipped LC-130 for the sunny environs of South Pole Station, where we had a flawless touchdown on the groomed skiway next to the station. This is our last stop before embarking on the traverse in about a week. Our main objective here is to prepare our vehicles and sleds for travel, and take some cool pictures.
The Amundsen-Scott South Pole station is located right at 90 degrees south latitude (ok, maybe not exactly there, but the station is within about 100m of 90 S). It’s named for the Norwegian explorer Roald Amundsen, who first set foot here in December of 1911, and for the British explorer Robert F. Scott, who followed closely behind in January 1912. The United States established a station here in 1957 as part of the International Geophysical Year, and it has been continuously occupied ever since. The current station, commissioned in 2008, is the third major station the U.S. Antarctic Program has built here. The prior station (the iconic geodesic dome) was disassembled and sent back to the US.
We are here in the height of the summer season, and there are ~150 people on station making the most of the relatively warm weather (-30 C, or -22F) for construction projects, moving cargo, and of course, science projects like ours. In winter, the station is much quieter with around 40 people spending the long winter keeping the station running.
For the first few days we’re here, our main job is to do very little. The South Pole Station sits on top of the East Antarctic Ice Sheet at about 10,000 feet above sea level, which is a big jump from the sea level McMurdo Station. The keys to acclimatization are to drink plenty of water and avoid exercise, though a little walking is fine. After about three days, we will be cleared to move on to more vigorous activities.
There is a marker placed at the geographic South Pole, designed by the wintering crew at the station. Every year on January 1, the new marker is placed and the marker from the past year is put on display inside the station. Since the entire station (and skiway, and cargo, and traverse vehicles) are on top of the ice sheet, the whole station moves along with the ice. The ice shifts about 30 feet per year toward the 40 degrees west line of longitude where it eventually becomes part of the Filchner-Ronne ice shelf. (Don’t worry though, at the current velocity, it will take tens of thousands of years to get there.)
The perhaps more familiar scene is from the ceremonial south pole – a post with barbershop stripes and a reflective ball on top, surrounded by the flags of nations signing the original Antarctic treaty. The two poles are a few hundred yards apart and are both worth a visit if you find yourself down this way. Tell ‘em Tom sent you.
Earlier today, we visited our cargo that we shipped from McMurdo and had a look at our sleds. It looks like everything has arrived, and as soon as our breath catches up with us, we will begin packing the sleds and pitching our tents!
