Velocity data with LADCP

  1. Please see the Data book for details of data.

  2. Data process
    3. Vertical profiles of velocity are obtained by the inversion method (Visbeck, 2002).

    Velocity profile only the range where the bottom track data were obtained.
    For the process the data, only the data within the range are used.

    Year/Month/Day Hour/Minutes Time_Zone: The time at the bottom of the cast.
    Degree_Latitude Minites_Latitude [N/S]: The latitude at the bottom of the cast.
    Degree_Longitude Minites_Longitude [E/W]: The longitude at the bottom of the cast.
    Magnetic_Deviation: Magnetic deviation calculated using IGRF.
    Flag: Flags of weak target strength. If target strength < 25.0, the value is set to "1". Data with the flag of "1" are bad mesurements.
