New research suggests a key Southern Ocean water layer has become saltier, denser and deeper since 2016, reversing earlier freshening trends as Antarctic meltwater input fell. Scientists say the shift could have implications for ocean carbon storage, deep-ocean heat uptake and the strength of global ocean currents, prompting discussion about what it means for climate projections.

Why now: New findings showing an unexpected salinity reversal in a major water layer have implications for climate and ocean circulation models
