North Ice Cap Ice Core Chemistry
An ice core was collected from the summit dome (1275 m elevation) of North Ice Cap near Thule, Greenland using an IDDO Hand Auger in May of 2014. The core was hand sampled under clean conditions and analyzed for major ion concentration and stable water isotope ratios. These data suggest that the mea...
