Latest Ocean surface topography Stories
Global sea level has risen 20 centimeters (eight inches) in the past 100 years, and the rate of rise is predicted to accelerate as Earth warms. NASA satellites will help us understand and deal with these changes.
A satellite that will help scientists better monitor and understand rises in global sea level, study the world's ocean circulation and its links to Earth's climate, and improve weather and climate forecasts, is undergoing final preparations for a June 15 launch from California's Vandenberg Air Force Base.
A NASA and French Space Agency (CNES) spacecraft designed to continue a long-term survey of Earth's oceans has arrived at Vandenberg Air Force Base, Calif., for final launch preparations.
Two different teams of ocean adventurers set records this winter crossing the Tasman Sea. One was the first expedition to kayak from Australia to New Zealand; the other was the first Australians to row across the Tasman Sea.
The tropical Pacific Ocean remains in the grips of a cool La NiÃ±a, as shown by new data of sea-level heights from mid-October of 2007, collected by the U.S-French Jason altimetric satellite.
The joint NASA/Centre National d'Etudes Spatiales Topex/Poseidon oceanography satellite ceased operations after nearly 62,000 orbits of Earth. The spacecraft lost its ability to maneuver, bringing to a close a successful 13-year mission.
For the first time, researchers have the tools and expertise to understand the rate at which sea level is changing and the mechanisms that drive that change. Sea levels rise and fall as oceans warm and cool and as ice on land grows and shrinks.
For the first time, orbiting satellites have observed and measured a major tsunami event in open ocean, the Indian Ocean tsunami that resulted from the magnitude 9 earthquake southwest of Sumatra on December 26.
