Microbiology Lab location on Fo'c's'le Deck



Overview

Microbial life has been discovered in cores recovered from as deep as 1 km below the seafloor. The Microbiology laboratory enables microbiologists to investigate this deep biosphere. The laboratory contains an anaerobic chamber with rock splitting and other sampling equipment for taking uncontaminated samples from the cores, a laminar flow hood for preparing uncontaminated samples for study, and facilities for incubating samples. There is also an epifluorescence microscope available for sample examination. Pressure vessels and -86°C freezers allow storage of samples under controlled conditions for future shore-based study. The ship also has facilities for conducting tracer experiments to quantify the extent of downhole contamination of the core by drilling fluid pumped down from the seafloor.
