Slideshow: Monthly maps of sea surface salinity (hover over images to pause the slideshow).
Maps of sea surface salinity are based on the latest algorithms (V5) developed by the Aquarius Calibration/Validation working group. These maps are produced by Norman Kuring, NASA Goddard Space Flight Center and include the following projections:

Click on the images (below) for a closer view.

In the maps, reds show higher salinity (40 grams per kilogram) and purples show relatively low salinity (30 grams per kilogram). For weekly views, click here then use the blue arrow to scroll through the gallery.
