Sea surface salinity as a proxy for Arctic Ocean freshwater changes ...
The changing Arctic freshwater content and distribution have significant implications for ocean circulation, climate, and water and biogeochemical cycles. The paucity of in-situ salinity measurements in the Arctic Ocean has limited our ability to study Arctic-Ocean freshwater variability. Although s...

The changing Arctic freshwater content and distribution have significant implications for ocean circulation, climate, and water and biogeochemical cycles. The paucity of in-situ salinity measurements in the Arctic Ocean has limited our ability to study Arctic-Ocean freshwater variability.

Motivated by the recent development of sea surface salinity (SSS) remote sensing, we explore the use of SSS as a proxy for Arctic freshwater changes.
