Our Rising Seas

Changing conditions in the Pacific have stirred up Earth’s largest ocean and redistributed its heat, piling up warm waters along U.S. Western shores and raising sea level in the process.

Launched on January 17, 2016, Jason-3 is a partnership that includes NOAA, NASA, CNES, and EUMETSAT.  The map shown here was generated using sea surface height measurements from the first 10 days (...
