Water temperature and salinity from profiling float 68399

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...本数据集所包含的盐度剖面（salinity profiles）已针对虚假数据点与传感器漂移问题完成校验。但尚未对每一条剖面应用漂移校正方案，因此使用时仍需自行承担相关风险（原文此处语句未完整结束）。
