本数据为在大连理工大学低温实验室开展的海冰生消过程冰下水体盐度变化观测试验数据。数据文件包含要素如下：冰生长和融化期间水下不同深度处的水体盐度。冰生长期间水下不同深度处水体盐度低温试验从2022年10月4日16:54开始，至2022年10月13日16:04结束，观测频率为1分钟，观测位置为水下30和45 cm处的水体盐度。冰融化期间水下不同深度处水体盐度低温试验从2022年1月8日18:00开始，至2022年1月18日15:00结束，观测频率为1小时，观测位置为水下5、15、20、30和40 cm处的水体盐度。

This dataset comprises observational experimental data regarding salinity variations of sub-ice water during sea ice growth and decay, conducted at the Cryogenic Laboratory of Dalian University of Technology.

The data file includes the following measured variables: water salinity at various underwater depths during sea ice growth and melting.

For the sea ice growth phase experiment: the low-temperature salinity measurement campaign at different underwater depths ran from 16:54 on October 4, 2022 to 16:04 on October 13, 2022, with a sampling interval of 1 minute. The measured depths were 30 cm and 45 cm below the ice.

For the sea ice melting phase experiment: the low-temperature salinity measurement campaign at different underwater depths ran from 18:00 on January 8, 2022 to 15:00 on January 18, 2022, with a sampling interval of 1 hour. The measured depths were 5 cm, 15 cm, 20 cm, 30 cm and 40 cm below the ice.
