Antarctic ocean water trend reversed, scientists warn

For decades, Antarctic Intermediate Water, a key sub-surface ocean layer, was becoming fresher as Antarctic sea ice melted. Since 2016, record-low sea ice has reversed this long-standing trend, altering salinity patterns in the deep ocean. Observers are highlighting the shift as a sign of rapid, ongoing change in the Southern Ocean linked to warming and sea ice decline.

Why now: New findings show a decades-old ocean salinity trend reversing since 2016 due to record-low Antarctic sea ice.
