The paper you are referring to is:
Microbial Activity at Gigapascal Pressures
Anurag Sharma, James H. Scott, George D. Cody, Marilyn L. Fogel,
Robert M. Hazen, Russell J. Hemley, and Wesley T. Huntress
Science 295: p. 1514 Feb 22, 2002.
There is a news article about it on p 1444.
The paper is from Carnegie Inst. in Wash DC.
They say the max P they use corresponds to 50 km of earth crust, or
160 km of water (much more than any known ocean).
(The link given will probably not lead to the article, beyond the
abstract, except for those with subscription.)
