Satellite imagery has revealed a yet-to-be-explained rise in the Southern Ocean's salinity. It could be a key factor in the decline of the region's sea ice.

The ocean around Antarctica is rapidly getting saltier at the same time as sea ice is retreating at a record pace. Since 2015 ...

Researchers have discovered a dramatic and unexpected shift in the Southern Ocean, with surface water salinity rising and sea ...

Which ocean is the saltiest? Of the world’s five ocean basins — Pacific, Atlantic, Indian, Southern and Arctic — the Atlantic has the highest salinity, says the National Weather Service.

Though satellites are capable of capturing salinity data from large portions of the ocean, data from buoys and in-water devices, such as the Velella velella sensors, provides localized, ...

Based on ocean model experiments, the researchers found that salinity effect on El Niño warming is very sensitive to zonal locations of salinity anomalies.

The salinity level in some seas is much higher than the rest of the ocean, like the Mediterranean. Some lakes, such as California's Mono Lake and the Caspian Sea in Asia, are saltier.

Another alarming possibility: Salinity, which is the concentration of salt in seawater, has a major effect on deep ocean currents that affect global climate, moving heat from the tropics to the poles.
