Presented at the 2013 Aquarius/SAC-D Science Team MeetingThe subtropical surface salinity maximum (SSS-max) in the North Atlantic was studied as part of the SPURS (Salinity Processes in the Upper Ocean Regional Study) experiment in 2012-2013. This paper documents the structure and variability of the SSS-max using Aquarius data during the two-year period August 2011 - August 2013. The Aquarius data show the seasonal migration and freshening of the SSS-max in good agreement with previous observations. The extent of the SSS-max has a surprisingly large amount of secular variability. It has decreased in area by about 20[%] over the time period that Aquarius has been making measurements. There has also been a general freshening of the area where the SSS-max is located, larger than any expected seasonal changes. The seasonal variability of sea surface salinity is documented. The SSS-max itself shows almost no seasonal variability of salinity, whereas to the north and south of it there is a well-defined seasonal cycle. This is consistent with the important role played by Ekman transport in the formation of the SSS-max.
