We sincerely thank Tamaki Ura, Yoshiaki Nose (Institute of Industrial Science, University of Tokyo) and Makoto Tsutsumi (Ocean Research Institute, University of Tokyo) for their skillful assistance during shore-based pressure tests. We also acknowledge the scientific group and crew of the R/V Hakuho-Maru (KH-98-1) during shipboard operation. The authors are very grateful to Mr. Gary J. Massoth and two anonymous referees for improving the manuscript. This study was partly supported by grants-in-aid from the Ministry of Education, Science, Sports, and Culture (Nos. 07558198, 09554029), and also from the RidgeFlux Project of the Science and Technology Agency of Japan.

N2 - This paper presents the first in situ flow-through chemical analyzer using a chemiluminescence (CL) method in the deep sea to a depth of 5200 m. The analyzer, called GAMOS (Geochemical Anomalies MOnitoring System), determines the concentration of dissolved manganese continuously using a H2O2-luminol CL method. A detection limit of 0.23 nM was obtained. The GAMOS was used successfully for hydrothermal plume observation.
