    • The Argo Project revealed the general characteristics of the salinity distribution in the global ocean.

      However, the Argo floats can only provide information up to 5 m below sea surface．

      However, the salinity in this 5 m surface layer changes dynamically with the effects of evaporation and precipitation between the atmosphere and the ocean, river runoff, and the freezing and melting of sea ice.

      In addition, the Argo floats are distributed only at an average rate of 1 unit per 300 km×300 km (an area similar to Hokkaido), and a detailed distribution of salinity cannot be obtained.
