However, a new study by Garcia - Eidell et al. shows that satellite - based methods produce reasonably accurate measurements of
Arctic sea surface salinity from season to season and year to year.
Recent progress toward satellite measurements of the
global sea surface salinity field, Satellites, Oceanography and Society, D. Halpern, ed., Elsevier Oceanography Series, 63, 367 pp.
The research team compared four different satellite - based strategies to map monthly changes in Arctic
sea surface salinity from 2011 to 2015.
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.
These advances include the near - global three - dimensional sampling by the Argo array of temperature and salinity profiling floats and spaceborne measurements of
sea surface salinity using the European Space Agency's Soil Moisture and Ocean Salinity (SMOS) spacecraft and NASA's Aquarius mission aboard the Argentine SAC - D spacecraft (which ceased operations in June 2015).
In section 4.5, the authors point out the need to simulate a number of features realistically and the model does not really do them very well, especially basic things
like sea surface salinity.

Pacific Sea Surface Salinity at End of Little Ice Age, Science, 295, 1511 - 154.
These data sets include weekly polar - gridded Level - 3 products of Aquarius L - band Normalized Radar Cross Section retrievals,
Sea Surface Salinity retrievals, and radiometer Brightness Temperature observations.
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).
Provide a forum for discussion on specific topics related to
improving sea surface salinity and soil moisture retrievals through dedicated working groups.
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.
Explore common L - band sensor and algorithm issues
for sea surface salinity and soil moisture retrievals derived by SMOS and Aquarius data.
Nonetheless, the findings demonstrate that satellite - based measurements of
Arctic sea surface salinity are reasonably accurate and successfully reflect changes due to river runoff, melting sea ice and glaciers, and ocean circulation.
[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.
Coral isotope measurements provide information on both sea surface temperature and
sea surface salinity, so they can indicate times of increased or decreased temperature and / or precipitation associated with changes in the position of the SPCZ.
NASA Aquarius level - 3 weekly polar - gridded Normalized Radar Cross Section,
Sea Surface Salinity, and Brightness Temperature data products are now available from NSIDC.
At this point, the NERP may also generate cyclones, pumping saltier water to the surface and creating small anomalies in
sea surface salinity.
and
Sea Surface Salinity, where there is also an interesting coincident decrease in salinity off the coast of Africa:
Measurement of
sea surface salinity is a new capability.
