Kryosfæren tilbyr tilgang til bevarte organismer som vedvarte etter siste miljøforhold. En protokoll er presentert for å samle og rense permafrost kjerner av jord og is. Fraværet av eksogene DNA-kolonier og antyder at mikroorganismer som detekteres representerer materialet i stedet for forurensning fra boring eller foredling.
