Trial instrument of in situ auto-chemical analysis for the purpose of long term observation in the ocean.

这项研究的目的是开发一种现场化学自动分析仪，以获得高精度的锰数据，这将对研究海底热液活动和冷渗漏具有重要意义。首先建立了一种高灵敏度的锰分析化学发光检测方法，然后构建了流通式原位锰分析仪伽莫斯(GAMOS)。对于现场流动分析，分别采用蠕动泵和隔膜泵两种泵系统进行短期和长期运行。通过将Gamos安装在新开6500潜水器(JAMSTEC)和R/V Hakuho Maru的CTD-Carousel采样系统上，分别于1997年7-9月和1998年3月调查了东太平洋海隆南部(D=2,600 m)和马里亚纳海槽南部(D=3,200 m)的热液活动地点。此外，我们还成功地获得了1998年9-10月阿尔文巡航期间的MN和温度(T)的详细数据。热液活动具有复杂的时空变化特征，表现为Mn/T的变化。这些在海上重复的Gamos操作显著提高了它的性能。在这个项目的最后一年，Gamos被安装到AUV“R-One”(工业科学研究所)上，建立了AUV原位分析系统，这在世界上是第一次。

The purpose of this study is to develop an in-situ chemical auto-analyzer for obtaining highly accurate Mn data, which will be essentially important to research submarine hydrothermal activity and cold seepage. At first we developed a highly sensitive chemiluminescence detection method for Mn analysis, then constructed a flow-through in situ Mn analyzer GAMOS (Geochemical Anomalies Monitoring System). For the in situ flow-through analysis, two pump systems, peristaltic pump and diaphragm pump, were employed for short term and long term operations, respectively. By attaching GAMOS to the submersible Shinkai 6500 (JAMSTEC) and a CTD-Carousel sampling system of R/V Hakuho Maru, hydrothermally active sites in the southern East Pacific Rise (D=2,600 m) and in the southern Mariana Trough (3,200 m) were surveyed in July to September, 1997, and in March, 1998, respectively. In addition, we successfully obtained detailed data of Mn and temperature (T) during the Alvin cruise in September to October, 1998. Complicated temporal and spatial variations of hydrothermal activity were characterized by Mn/T variations. These repetitive GAMOS operations at sea improved its performance significantly. In the last year of this project, GAMOS was installed to the AUV "R-One" (Institute of Industrial Science) to establish an AUV-in situ analyzer system for the first time in the world.
