Outline of Ocean Current Data
This is the ocean current data obtained from the drift by vessels, observation by GEK and ADCP and ARGOS surface buoy displacement. In addition, the position of the ARGOS surface buoy is the observation position which becomes the middle value of the before and after the position. Temperature and salinity are data of sea water withdrawn with the intake method at the time of observation of ADCP, etc.
