Summary

Story summary

A study analyzed 589,312 hydrographic profiles from the Southern Ocean to assess upper-ocean changes from 2005 to 2022.
It examined the mixed layer depth and identified warm-water characteristics.
The study found a warming trend of 0.004 °C per year in the warm-water layer and a surface freshening.
It notes a significant wind–turbulence link in the mixed layer, indicating wind drives oceanic turbulence.
