Die Kryosphäre bietet Zugang zu den erhaltenen Organismen, die im Rahmen früherer Umweltbedingungen bestehen blieb. Ein Protokoll vorgestellt zu sammeln und Permafrostkerne von Böden und Eis dekontaminieren. Die Abwesenheit von exogenen DNA-Kolonien und schlagen vor, dass Mikroorganismen detektiert das Material darstellen, anstatt Kontamination durch Bohren oder Verarbeitung.
