A NASA-built instrument aboard an international satellite has made its first global map of the salt in the surface of Earth's seas, just three months after the high-tech sensor rocketed into orbit.

Global maps of sea-surface salinity are particularly helpful for studying the water cycle, ocean-atmosphere exchanges and ocean circulation, which are all vital components of the climate system ...

Scientists find rising ocean salinity in Antarctica, reversing decades-long trends and accelerating sea ice loss.

A sudden salinity spike in the Southern Ocean is accelerating Antarctic ice loss and triggering a dangerous climate feedback ...

A team of researchers has developed an innovative approach that maps the soil salt contentaround the world with an exceptional detail of 10 meters.

The ocean's salinity levels affect how much sea ice forms and, in turn, affects Earth's albedo. The more salt there is, the more the freezing point drops, making it harder for ice to form.
