Antarctic Sea Ice Decline Triggers Ocean Salinity Increase

  • The rapid decline of Antarctic sea ice since 2016 has triggered a dramatic shift in the Southern Ocean's salinity.
  • A vast layer of the Southern Ocean, extending from 2,300 to 4,000 feet deep, has seen a sharp increase in salinity.
  • This shift reverses decades of freshening and echoes changes that may have driven past ice ages.
  • The salinity increase could potentially shift storm tracks and accelerate sea-level rise globally.
  • Researchers documented these changes in a paper published on Wednesday.
