Introduction
We have been developing newly small and simple in situ system for pCO2 measurement using spectro-photometric technique.
A lot of observations to obtain the fate of CO2 in the atmosphere which is related with long term climate change have been carried in the world (Fig.1). However, the sea surface pCO2 observations on research vessels and commercial ships concentrated in the North Atlantic and North Pacific. To obtain the spatial and temporal variation of surface pCO2 in the whole ocean, new simplified automated pCO2 measurement system is needed. We have been developing newly small and simple in situ system for pCO2 measurement using spectro-photometric technique. We also consider the observation system using our pCO2 sensor. This study is made under the Japan EOS Promotion Program (JEPP).
