La criosfera ofrece acceso a los organismos conservados que persistieron en las condiciones ambientales del pasado. Un protocolo se presentará a recoger y descontaminar los núcleos de permafrost de suelos y hielo. La ausencia de colonias exógenos y el ADN sugiere que los microorganismos detectados representan el material, en lugar de la contaminación de la perforación o de procesamiento.
