5. In the paragraph above Fig. 7, “all water salinities were 0%” should be “all water salinities were 0‰”.

We would like to apologize for any inconvenience these errors may have caused.

The original article has been updated.

1. In the last sentence in abstract, “approximately 0.1 °C and 0.5%” should be “approximately 0.1 °C and 0.5‰”.

2. In the last sentence above experimental apparatus section, “salinity range of 0–35%” should be “salinity range of 0–35‰”.

8. In the Conclusion section, “up to 0.1 °C and 0.5%” should be “up to 0.1 °C and 0.5‰”.

After publication of this article¹, it was brought to our attention that the mathematical expressions ‘‰’ were mistakenly replaced by ‘%’ for salinities. Details are listed below.

7. In the paragraph below Fig. 7, “for salinity, the difference is less than 0.5%” should be “for salinity, the difference is less than 0.5‰”.

6. In the caption of Fig. 7, “all the water salinities are 0%” should be “all water salinities are 0‰”.

3. In Double-edge filter section, “salinity range of 0–35% ” should be “salinity range of 0–35‰ ”.

4. In the paragraph above Fig. 6, “salinity of 0%” should be “salinity of 0‰”; “20.59 °C and 0.45%” should be “20.59 °C and 0.45‰”; “0.45% for salinity” should be “0.45‰ for salinity”.
