Yon echantiyon debaz, refè soti nan anba tè oswa lanmè etaj la, se pa nan kondisyon primitif, akòz chanjman nan presyon menmen pandan y ap k ap deplase li nan sifas la, ki soti nan fon lanmè gwo nan kondisyon atmosferik. Kòm yon rezilta mekanik, fizik, ak pwodui chimik pwopriyete kòm byen ke kondisyon lavi pou mikwo-òganis nan byosfr nan gwo twou san fon yo siyifikativman chanje.

A core sample, recovered from beneath the land or sea floor, is no longer in pristine condition, due to the enormous pressure change while moving it to the surface, from great depths to atmospheric conditions. As a result mechanical, physical, and chemical properties as well as living conditions for microorganisms of the deep biosphere are significantly altered.
