Brief Description of Research
1. CO2 flux at the surface ocean from ship-board observation
Ocean surface CO2 flux is measured by VOSs (volunteer observation ships) program in the north Pacific. NIES is operating CO2 measurement system on board cargo ships in the north Pacific from 1995 to the present. Results identified the distribution, seasonal and inter-annual change in CO2 source and sink intensity of the north Pacific. Program is still ongoing with two atmosphere/ocean VOSs and two atmosphere VOSs, in which collaborations with NIWA (New Zealand), CSIRO (Australia) are continuing. In 2002, collaboration with Professors D. Wallace and A. Kortzinger of University of Kiel was done to operate cargo ship CO2 observation in the north Atlantic, using CO2 system developed by Dr. Nojiri on board a car carrier between Europe and US, to identify the CO2 sink intensity of the north Atlantic. Observing pCO2 program with Gothenburg University is also continuing to operate pCO2 system on board Swedish Arctic survey vessel. These data sets are joining CDIAC (US) data set and newly designed collaboration of global scientists for ocean surface CO2 study database (SOCAT) under UNESCO/IOC, in which I am working the chair of Pacific regional activity.
2. Development of on board monitoring system about CO2 and related ocean biogeochemical parameters
I developed a novel pCO2 equilibrator for on board ship observation. The pCO2 equilibrator and CO2 system are operated for the monitoring program by VOSs in the Pacific and north Atlantic. NIES organized jointly with UNESCO/IOC ocean carbon program (International Ocean Carbon Coordination Program) of ocean pCO2 measurement systems. Two campaigns have been carried out in 2003 and 2009 utilizing a seawater pool facility in Japan. This facilitates global improvement of pCO2 observation technology and results in the increasing accuracy of CO2 flux estimation.
3. Biological impact of ocean acidification
From 2008, Ministry of Environment, Japan is funding a manipulation experiment as ‘Experimental study of ocean acidification impact on calcifiers’ examining impact of ocean acidification for marine organisms, which is leaded by me. I developed a precise pCO2 controlling system for manipulation experiment. I started collaboration with EU ocean acidification group of scientists (EPOCA) to have common knowledge about accurate laboratory set up for ocean acidification experiment.
