      The Funka bay in Hokkaido, Japan, faces the Western North Pacific Ocean. Open ocean water flows into the bay twice a year in spring and autumn. The waters stay in the Funka bay during a certain period of summer and winter. The Funka bay is a model sea area, where we can examine the water quality  changes in time series within the same water mass.


      The Training Ship Ushio-maru is used mainly to observe the coastal area in Hokkaido. This survey measures not only basic ocean parameter such as water temperature and salinity, but also organic gas components including isoprene, nutrients, and dissolved inorganic carbon.
