Major Southern Hemisphere Ocean Layer Shifts, Raising Questions About Heat and Carbon Storage

Antarctic Sea ice decline makes key ocean water mass saltier, raises warming concerns

BENGALURU: A decline in Antarctic sea ice since 2015 has reversed decades of freshening in a major ocean water mass, making it saltier and denser, a study

Decline in Antarctic sea ice has increased salinity: Researchers

The study noted that the saltier AAIW causes disruption in how ocean layers are stratified.

The deep ocean’s protection against warming started to change in 2016. Nobody knows what happens now

Melting sea ice protects the deep ocean from warming – but when sea ice levels declined, the system began to break down.

Major Southern Hemisphere ocean layer shifts, raising questions about heat and carbon storage

The Antarctic Intermediate Water (AAIW)—a vast layer of fresh water spanning much of the Southern Hemisphere's ocean—has rapidly reversed its long-term trends in salinity and density, according to new research. The AAIW helps store carbon, supply oxygen and drive global ocean currents.

Antarctic Sea Ice Loss Alters Ocean Freshwater System

MELBOURNE, Oct 29: Research from the University of Melbourne and Indian Institute of Science indicates that Antarctic Intermediate Water (AAIW) is becoming saltier and denser due to a significant decline in Antarctic sea ice. This change has serious implications for deep-ocean warming and sea levels. The study, published in Nature Climate Change, reveals that prior

Environmental News Network - Antarctic Sea Ice Loss Batters Ocean’s Freshwater Engine

The Antarctic Intermediate Water (AAIW) – a vast layer of freshwater spanning much of the Southern Hemisphere’s four oceans – has rapidly reversed its long-term trends in salinity and density, according to new research led by the University of Melbourne and the Indian Institute of Science.
