Aquarius Sea Surface Salinity on Rotating Globes 2012

This data visualization shows sea surface salinity (i.e., ocean salt concentration) over a ten year period (2011 to 2021). Warm colors (orange to yellow) are areas of high salinity/hot tropics. Cooler colors (blue to violet) are fresher waters, many of which can be seen coming from rainy/river/wetter tropics. The heat of the sun forces evaporation at the ocean s surface, which puts water vapor into the atmosphere but leaves minerals and salts behind, keeping the ocean salty. The salinity of the ocean also varies from place to place, because evaporation varies based on the sea surface temperature and wind, rivers and rain storms inject fresh water into the ocean, and melting or freezing sea ice affects the salinity of polar waters. Sea Surface Salinity (i.e., ocean salt) colorbar. Date overlay for above data visualization. Example composite animation using the colorbar and date overlays.

Rectangular flat map projection (Atlantic-centered) with grid lines showing Sea Surface Salinity measurements taken by Aquarius between September 2011 and September 2014. The Aquarius spacecraft is designed to measure global sea surface salinity. It is important to understand salinity, the amount of dissolved salts in water, because it will lead us to better understanding of the water cycle and can lead to improved climate models. Aquarius is a collaboration between NASA and the Space Agency of ArgentinaThis visualization celebrates over three years of successful Aquarius observations. Sea surface salinity is shown on a flat map using simple cartesian and extended Molleide projections. Versions are included with and without grid lines, and in both Altantic-centered and Pacific-centered projections.The range of time shown is September 2011 through September 2014. This visualization was generated based on version 3.0 of the Aquarius data products.

The rapidly evolving ocean salinity shifts come to life through Aquarius blue represents the lowest. The large region of high salinity that stretches across the North Atlantic is the saltiest spot in the open ocean. The Amazon River releases a fresh water plume that heads toward Africa or bends up to the Caribbean depending on the prevailing currents. The seasonal melting of sea ice causes a sharp decrease in sea surface salinity in the Labrador Sea and the coastal waters of Greenland.

Sea surface salinity is shown at various locations around the globe highlighting the following:the Atlantic Ocean is generally much more salty than the Pacificlow salinity waters in the Eastern Equatorial Pacific are transported westwardhigh influxes of fresh water from the Amazon River basin can be clearly seenlow salinity waters are transported by the Labrador current to the southhigh influxes of fresh water from the Ganges River basin can be seen keeping the Eastern Indian Ocean lower salinity than the Western Indian OceanThe range of time shown is December 2011 through Decemeber 2012.
