The migration South has begun again. This year I’m heading back as the equipment operator on a small 4-person team: The West Antarctic Support (WAS) Recovery Crew.
Two years ago (2012-13) there were several active camps in West Antarctica: Pine Island Glacier (PIG), the West Antarctic Ice Sheet (WAIS) Divide, WISSARD, Byrd, and Siple. My post summarizing these camps and projects can be found here. With the Government Shut-Down last year the removal of the PIG and Byrd camps could not be completed and the supply berms were left to drift over. These regions have large accumulation rates – averaging over a meter annually in some coastal areas in addition to drifting snow.
Pine Island Glacier is quite a ways from McMurdo, way out “west” towards the peninsula (point A on the map below). Because it’s so far away and because the weather is so notoriously bad Hercs heading out to PIG relied on WAIS as a fueling point and Byrd as their back up. It’s easier to fly to WAIS so to initially establish PIG camp a traverse was organized to haul materials that were flown into WAIS. The projects utilizing PIG were completed in Feb 2013. The plan for cleaning up the camp was a tractor team to traverse from WAIS to PIG, collect the materials, and haul them back to WAIS where it would be used or flown via LC-130 to McMurdo. Then the government shutdown happened and the traverse had to be cancelled…So this year, two years since it was left, we’re going to try again. Our team has been organized to augment the traverse, making sure this stuff gets unburied and removed before it flows into the ocean.
The rough schedule is to fly down to McMurdo in early November. After getting our equipment together (tents, stoves, safety and comms gear etc) we’ll fly out to WAIS. From WAIS we’ll get on a Twin Otter and head out to PIG by mid-late November. We won’t have the support of a full camp, it will just be the four of us and a few small tents (Arctic Ovens – “tent-city” tents). We’ll dig out the equipment, get it up and running, and use it to help dig out the supply berm, establish a field skiway for Twin Otters, and greet the PIG Traverse when the roll in hopefully around Dec 10. Once the traverse is loaded up and underway we’ll fly back to WAIS and out to Byrd. There isn’t a traverse planned for Byrd, so our job will be to repair some known broken equipment and try to move supplies to a new berm, or at least the snow surface as able. By late January we should be heading back to McMurdo.
As I mentioned earlier, the weather in West Antarctica is notoriously bad and delays are expected. Our schedule is flexible with options to assist with other projects if we are delayed longer than expected at one site or other.
It will be a challenging season. At WAIS there will be very limited text email, satellite phones, and radio, but there will also be cooks and galley (mess tent), and even snow melters for showers. At PIG it will be roughing it, even by Antarctica standards. It’s not as extremely cold as at Pole, but it’s wetter, which can be even more difficult. We won’t have any showers, or bathrooms, nor cooks. We’ll sleep in small unheated tents and hope for good weather. It’s close to the coast, but not close enough to see animals or water, mostly it will be back in the flat white…

Great photos. Thanks for keeping us up to date on your adventures. I hope all goes well in this recovery effort. We miss you!
Thanks Amy! I hope you guys have a wonderful holiday season up North!
Yikes; cleaning out PIG sounds like a challenge. Hope all goes well.
