Procedures for Removing Surface Contaminants from Deep Ice Cores.
Abstract
The surfaces of the deep ice cores from Greenland and Antarctica were contaminated during drilling at concentration levels several orders of magnitude greater than those found in the uncontaminated ice. Several procedures for removing these contaminants were studied. Ultrasonic vibration followed by self-cleaning in meltwater was found to be the most effective procedure for removal of surface contamination. (Author)
