Water temperature and salinity from profiling float 70697

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...本数据集的盐度剖面已针对虚假点（spurious points）与传感器漂移（sensor drift）完成核查，但尚未对每一条剖面应用漂移校正，因此使用时仍需自行承担相关风险（原文后续内容未完整呈现）。
