Summit Station Science

Recent visitors to Summit Station include Harro Meijer’s team from the Netherlands, which spent a whirlwind few days on station taking shallow ice cores from a specially prepared snow field. Meijer is studying isotope diffusion in ice cores; his results will help experts better interpret information from ice cores being studied to reconstruct climate history.

The Meijer team harvested shallow ice cores to about two meters depth from an isotopically enriched site (seen here within the flag border) near Summit Station. They also conducted maintenance on dataloggers at the site.

Later, researchers processed the cores, slicing them into 1-2 cm-thick layers and packing them in plastic bags for shipment back to the Netherlands.
