| Research Abstract |
Pitch, roll, and heading variationsof the platform on which ADCP is mounted will affect the measurements of water velocity of ADCP. It is considered that the magnitude of velocity error is especiallylarge in the western boundary current. In order to eliminate errors due to pitch and roll biases, attitude variations were measured by GPS on the ADCP mounted Ferry boat which across the Kuroshio in the Tokara strait. As a result, when in large attitude variations, up to 11% errors were included in the ADCP velocity data.
