Summit Storms and Work

We've spent the past few days huddled up in the Big House hiding from the storm that ripped through Greenland, with temperatures dipping to -14 F and winds up to 40 knots. Luckily, all of our tents held up and we managed not to lose anything in the wind or under the drifting snow. During Condition 1 weather no one is allowed to travel alone outside, we radio the camp manager each time we're leaving or arriving at a location, and no one can leave the station without a GPS, radio, and emergency beacon.

The Summit Science crew allowed us to use some space inside the Summit Operations Building to prepare our radar sleds and mount various GPS antennas to our snowmobiles. Being allowed to work inside saved us a few days while waiting out the nasty weather. Big thanks to the operations crew!

Once the weather cleared, we spent Thursday and Friday building our sleds, organizing our cache loads, and testing the radar equipment. The Twin Otter plane is supposed to spend Saturday and Sunday dropping off ice core boxes, extra food, snowmobile gas, and propane to four locations along our route.

After setting up all the sleds and testing the equipment, we were able to to get a tour of the Temporary Atmospheric Watch Observatory. Located 1/2 mile south of the Big House (in the clean air sector), the TAWO measures temperature, wind speed, humidity, incoming radiation, atmospheric black carbon, and other particulates floating around in the air. We walked past the GISP2 borehole, which was one of the main reasons Summit Camp was established in the 1990's. GISP2 drilled down 3053 m through the ice sheet and into the bed rock, the deepest ice core ever recovered at the time. After dinner, Gabe gave a 20 minute science lecture on preliminary results from the 2016 GreenTrACS traverse and our plans for the upcoming traverse.
