On Tuesday morning, John helped the LANL and UAF teams by laying out snow grid and shallow well positions. Anna, Sasha and Andy augered runoff wells, while Cathy picked-up Joel, Garrett and the new 2 inch diameter SIPRE corer from the airport. We have been using a standard SIPRE for several years now, but had reason to believe that a smaller diameter core would facilitate collection of some deeper permafrost samples. Coring began mid-afternoon and the new corer worked very well; punching 6 cores in a few hours. We will meet up again with the LBNL group this evening to prepare for laying out additional coring locations tomorrow.
