摘要：

In order to take measures against environmental impacts during the process of mining seafloor massive sulfides (SMS), it is important to measure some of the components of hydrothermal origin with high resolution in time and space on-site as well as to understand the ecosystem in the hydrothermal environments. The adoption of spectrophotometry for measuring concentrations of the components, such as H2S and Fe, is proposed in the study. It is necessary to extract the absorbance spectrum of each component from the one of seawater for the first step. Applying a determination method referred to as principal component regression (PCR), the fundamental
