Abstract
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 a nalyzer, 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 s uccessfully for hydrothermal plume observation. (C) 2001 Elsevier Science B .V. All rights reserved.
