f. Subsurface salinity.

The article investigates the changes in ocean subsurface salinity in 2013. Topics discussed include the average gridded salinity anomalies at standard depths from the surface to 2,000 meters, the zonally-averaged difference between salinities in the Pacific Ocean and the long-term averages, and the increased salinity reported in the subtropical and tropical North Atlantic and the in the subpolar North Atlantic.
