Abstract

In order to develop new techniques and instruments for in situ measurement, we conducted combined measurement of physical, chemical and biological activities during the scientific exploration in the area of Hatoma Knoll in April to May, 2005. In this exploration, we first deployed a newly developed 'Integrated in situ Analyzer-Gene (IISA-Gene)', which is a micorfluidics-based instrument capable of doing PCR (polymerase chain reaction) in deep sea environments. In this paper, the overview of the system and the results of the first deployment will be described. Some perspectives for further development of the technologies for combined in situ measurement will also be discussed.
