Steffensen (University ofCopenhagen) and Bruce Vaughn(INSTAAR) inspect the ice core drill ontop of Flade Isblink, a small ice cap at81°N in NE Greenland, summer 2006.This collaborative project with theNiels Bohr Institute at the University ofCopenhagen tested new drilling fluidsfor use in the upcoming IPY-NEEMdeep drilling, as well as obtaining anice record to see if this small isolatedice cap survived the Holocene climaticoptimum.
