Water temperature and salinity from profiling float 68301

The salinity profiles have been checked for spurious points as well as sensor drift. The drift correction has not been applied to each profile so ther is still a use at your own...已针对虚假点（spurious points）与传感器漂移（sensor drift）对盐度廓线（salinity profiles）开展核查。但尚未对每条廓线应用漂移校正（drift correction），因此使用时仍需自行承担风险。
