On - the - ground measurements are notoriously difficult in the harsh environment of the Arctic, but satellites could help close the gap in
measuring sea surface salinity.

There's no satellite in space that's capable of directly
measuring ocean acidity, but an international team of scientists writing in the journal Environmental Science & Technology described last week how satellite measurements of
sea surface temperatures,
salinity and plankton activity could be combined and used to estimate pH.
[5] Linsley et al. (2006) reconstructed
sea -
surface temperature and
sea surface salinity in the southwest Pacific starting circa 1600CE by
measuring the oxygen isotopic composition of four Porites coral records from Rarotonga and two from Fiji.
The group highlighted the added value of
measuring paired coral strontium / calcium ratios (Sr / Ca) and oxygen isotope ratios (δ18O), two key proxies for
sea surface temperature that are often referred to as paleothermometers (δ18O also reflects
sea surface salinity).
This ocean - to - land moisture transport leaves an imprint on
sea surface salinity, making this «nature's rain gauge» to
measure the variations of the water cycle.
