JOIDES Resolution Microbiology Lab
ODP cores have shown that bacterial life exists as deep as I km below the seafloor. The microbiology laboratory aboard JOIDES Resolution 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 will also be an epifluorescence microscope available for sample examination. Pressure vessels and -80°C freezers allow storage of samples for future study under controlled conditions onshore. The JOIDES Resolution also has facilities for conducting tracer experiments, both to quantify the extent of downhole contamination of the cores (by drilling fluid pumped down from the sea surface) and to measure the growth rates of bacteria recovered from deep beneath the sea floor.

Glove Bag (Anaerobic Chamber)
There is a Coy anaerobic chamber in the microbiology lab. This is a two person, medium size model with gloves on opposite sides of the polymer glove bag. The glove bag is 5' L X 40" H X 32" D. There is an automatic air lock for taking samples in and out of the glove bag chamber. The door to the lock is 9"W X 12" H. The air lock is automated and a single push of a button automatically cycles the air lock through a programmable sequence of applying a vacuum and flushing with nitrogen, carbon dioxide and hydrogen. This results in consistent vacuum and pressure levels. There is a catalytic box with heater to control oxygen and humidity. There is a flame device for sterilizing loops. Plumbed into the glove box are both nitrogen and an anaerobic gas mixture of 5% hydrogen, 5% carbon dioxide and the balance nitrogen.
