1. Objectives

The oceans play an important role in the global carbon cycle, acting as a large carbon sink. However, the temporal and spatial variability is very large. The North Atlantic and North Pacific are the largest sink areas, whereas the Eastern Equatorial Pacific is the largest source. The integration of extensive measurements covering the global oceans with sufficient temporal coverage is the only promising approach to identify the sources and sinks in order to estimate the oceanic net CO2 flux, and so observations should be shared among all countries, with Japan's primary mission being to observe the Pacific Ocean. An accurate knowledge of oceanic sinks and sources, together with their temporal variability, will contribute to modeling of the global carbon cycle for forecasting climate changes.
