Off the coast of Western Australia, the Southern Indian Ocean is becoming significantly less salty, and scientists say it’s ...

A huge stretch of the Southern Indian Ocean is rapidly losing its salt, and scientists warn this subtle shift could quietly disrupt global ocean currents and marine life in unexpected ways.

Han’s team estimates that the area covered by salty seawater in this Southern Indian Ocean region has shrunk by about 30% over the past 60 years. They describe it as the fastest freshening seen ...

New research from the University of Copenhagen suggests that volcanic eruptions during the Ice Age may have triggered sudden climate change by disrupting the Atlantic Meridional Overturning ...

Six projects will investigate innovative approaches that could help slow Arctic sea ice loss and reduce escalating ...

But scientists say a warming world is throwing off this balance. As Arctic ice melts, freshwater enters the North Atlantic — making the ocean water less dense, so it is less likely to sink. As a ...

The oceans are mostly composed of warm salty water near the surface over cold, less salty water in the ocean depths. These ...

The southern Indian Ocean off the west coast of Australia is becoming less salty at an astonishing rate, largely due to ...

Climate change is rapidly freshening one of Earth’s saltiest ocean regions in the Southern Indian Ocean, potentially disrupting circulation.

A powerful shift is unfolding deep beneath the Pacific. After months of La Niña dominance, ocean heat is rising fast and trade winds are faltering.
