Scientific paper

The validity of data on trace metals in Antarctic and Greenland ice and snow reported by LaViolette (1987) is questioned. It is argued that these data are probably in high positive error by up to several orders of magnitude because of major unsolved contamination problems during field sampling and/or laboratory analysis. It is suggested that the hypothesis that the trace metals found are debris from the 1908 Tunguska explosion is incorrect. In a reply by LaViollete, the ice core decontamination procedure used in the original study is defended, citing examples of other studies which have used similar procedures. The need for further trace element studies in polar snow and ice is emphasized.
