The Japanese ship Chikyu is the world’s largest research drilling vessel. From 26 July to 27 September 2012 researchers are sampling from the ship off the Shimokita Peninsula in the northwestern Pacific.

The researchers onboard the drilling vessel Chikyu have reached their goal with ”Expedition 337 Deep Coalbed Biosphere”: To drill down to 2,200 meter below the seafloor and collect samples from the deeply buried coal formations. And the core samples are of a high quality. Postdoc Mark Lever participates in the research expedition and coordinates the group of scientists working with molecular biology. They will undertake tasks such as counting the microorganisms by means of DNA analyses, and study whether the inflow of CO2 into the sediment stimulates activity and growth, and whether the microorganisms absorb carbon dioxide.
