UVSHIP as well as patch_hcorr.py was applied to the os38nb and os38bb. No calibration adjustments were done, although an argument to apply a slight rotation to the os38 could be made. The wh300 had low data quality during high seas. This is likely due to bubble interference, and resulted in large chinks of data loss.
