Yesterday was a very productive day for the FirnCover crew:
- Darren and Max dug snow pits to measure snow density and stratigraphy from last winter.
- GPS surveys were conducted to gauge how much the camp actually moves from year to year: how much the ice is spreading and it’s elevation (loss or gain). These measurements along with other factors can contribute to determining the total mass balance of the ice sheet.
- A 16 m (52.5 ft) ice core was drilled successfully (performed early in the morning before temperatures got warmer). The core was divided into 160 individual 10 cm (~ 4 in) segments and stratigraphy and density measurements were logged. A compaction instrument was then installed over the ice core hole.
- Aleah’s permeability test was run successfully.
- Darren repaired a generator that had failed that morning. A replacement was requested “just in case”. (The ice sheet is not a place you want to spend time in without a working generator.)
After a long day of hard work, they enjoyed a delicious dinner Baptiste made: breaded fish, alfredo sauce, hashbrowns, cooked vegetables and a refreshing “slushy” white wine. (Sounds better than what I had last night!)
The plan for today is to pack up at KAN-U early and make the traverse back to DYE-2 before potential bad weather blows in. The weather forecast expects head winds of up to 35 knots – too dangerous for traversing. Let’s hope they make it back to their home base well before the high winds kick in later in the afternoon.
Be safe, guys!
Barbara, I’m so glad they’re able to communicate with you regularly and keep you and thus all of us up to date on progress.
Mike’s been calling almost daily to keep me updated! 🙂
