This data visualization shows the areas where sea surface salinity has increased (depicted in red) and descreased (depicted in blue) over ten years (2011 to 2021).

This data visualization shows the areas where sea surface salinity has increased (depicted in red) and descreased (depicted in blue) over ten years (2011 to 2021).

The heat of the sun forces evaporation at the ocean's surface, which puts water vapor into the atmosphere but leaves minerals and salts behind, keeping the ocean salty. The salinity of the ocean also varies from place to place, because evaporation varies based on the sea surface temperature and wind, rivers and rain storms inject fresh water into the ocean, and melting or freezing sea ice affects the salinity of polar waters.

This depicts the surface salinity concentration trend from 2011 to 2021.

Colorbar for decadal trend of sea surface salinity covering 2011 to 2021. Areas in red are where surface salinity measurements have increased and areas in blue are where surface salinity has decreased.
