The authors express their sincere thanks to Prof. Dr. Bernard Wood, Department of Earth Sciences, University of Bristol and an anonymous reviewer for constructive reviewing comments which helped to improve the manuscript. The authors would like to thank Mr. T. Kaneko and Mr. T. Horiuchi, Yokohama National University, for their experimental help. The authors would like to thank all of the members of Hakureimaru II cruise over the Suiyo Seamount. This research was funded by the Ministry of Education, Culture, Sports, Science and Technology of Japan through the Special Co-ordination Fund for the Archaean Park Project, an international research project on interaction between the sub-vent biosphere and the geo-environment.

N2 - Deep-sea hydrothermal systems are of significant interest as a new scientific frontier in a number of fields. This report analyzes data obtained in ocean-drilling surveys at submarine hydrothermal vents on the Suiyo Seamount in the Izu-Bonin Arc, Pacific Ocean. These surveys obtained direct data regarding subjacent extreme environments under extreme conditions of 308°C and greater than 14 MPa. Evaluation of the vertical distribution and stereochemistry of amino acids in such a vigorous hydrothermal system leads to a model of deep-sea subterranean chemistry and biology that describes a lack of evidence of abiotically synthesized amino acids. Large enantiomeric excesses of L-form amino acids supported the existence of a vigorous subjacent microbial oasis in a hydrothermal system.
