Abstract:
Drilling and laboratory manipulations of glacial ice cores introduce contemporary microbes and biomolecules onto the cores. We report herein a systematic comparative study of several decontamination protocols. Only treatment with 5% sodium hypochlorite eliminated all external contaminating microbes and nucleic acids while maintaining the integrity of those within the cores.
