All samples were collected during IODP Expedition 329. We thank the Expedition 329 captain, crew, technicians, and science party of the R/V JOIDES Resolution for their assistance during the expedition. We especially thank Steven Midgley for his postcruise help in providing logging data. We thank Dr. Mark Alexander Lever for very helpful comments. Postexpedition analyses were funded by the National Science Foundation (NSF) Division of Ocean Sciences (grant OCE-1130735) and the NSF-funded Center for Dark Energy Biosphere Investigations (grant NSF-OCE-0939564). This is a contribution to the Deep Carbon Observatory (DCO). It is Center for Dark Energy Biosphere Investigations (C-DEBI) contribution #335. Top of page \| Previous \| Next
