No respite in the weather, but Heike and I headed back out to deploy a PAR (photosynthetically active radiation) sensor for Christopher Krembs and a pressure guage to measure changing water depth beneath the landfast ice. Deployment of both of these went easily, requiring just some holes in the ice with the auger. A final attempt to freeze-in the plastic sheets was foiled once again by the chainsaw freezing-up and so they completed their second round-trip to the sea ice.
Lesson of the day: A 3m long 6-inch diamater air-filled pipe is surprisingly buoyant.
