New research using salinity data from NASA's Aquarius instrument has given scientists an unprecedented look at a key factor involved in the formation of an oceanic wave feature in the tropical Pacific and Atlantic Oceans that influences global climate patterns. Previous observations of tropical instability waves have been limited to satellite observations of sea surface temperature, sea level, ocean surface wind, and ocean surface chlorophyll abundance, as well as sparse direct ocean measurements. Aquarius provides an unprecedented opportunity to observe their salinity. [Source: NASA Jet Propulsion Laboratory]
