    Relationship of Salinity, Density and Temperature

    Assuming a closed system...
    Temperature and Density: Inverse (as temperature increases, density decreases)
    Salinity and Density: Proportional (as salinity increases, density increases)
    Temperature and Salinity: None (as temperature changes, salinity remains the same)

    Animations of Satellite and Surface Oceans Data

    These websites provide animations that provide stunning views of the Earth created from satellite sensor data. These data are the combined efforts of ocean and atmosphere scientists from many organizations.

    NASA animations: Average Sea Surface Temperature, Salinity and Density
    (This website has links to animations on a globe and a mercator map.) Animations include:
    * Average Sea Surface Temperature (SST )
    * Average Sea Surface Salinity (SSS)
    * Average Sea Surface Density (SSD)
    NASA Animations: (mercator) 1 year: December 2011 through December 2012 showing:
    Global Sea Surface Salinity
    Salinity and ocean circulation
    Salinity and global seawater migration
    NOAA animations: Sea Surface Temperature (World mercator map, last 6 months)
    Monthly Isopycnal & Mixed-layer Ocean Climatology (MIMOC): Animations show pycnocline (temperature and salinity) data of different parts of the world.

    The NASA animations provide views of how salinity, temperature, and density change over the course of a year.
