There was a substantial amount of bad data at the surface due to interference from bubbles. That was removed. There where a few vertical stripes that did not exist in the os38, a few of which coincided with speed changes, so these where removed.

I decided to reset some editing there as I originally thought # it was caused by bubble interference and removed quit a bit of # data. Again at dday 72.0 I reset some editing to gain back what might # be a real physical feature and not just bubble interference in the # wh300. ------------------------------------------------------------ Final calibration for consistency with neighboring cruises: AMP=1.01 ANG=-0.2 quick_adcp.py --steps2rerun rotate:navsteps:calib --rotate_angle $ANG --rotate_amplitude $AMP --auto catwt **watertrack** ------------ Number of edited points: 58 out of 73 amp = 1.0031 + -0.0001 (t - 67.2) phase = -0.06 + -0.0174 (t - 67.2) median mean std amplitude 1.0020 1.0031 0.0114 phase 0.0340 -0.0601 0.8468 ------------ ------------------------------------------------------------- ### 5.
