A new NASA-French space agency oceanography satellite launched today from Vandenberg Air Force Base, Calif., on a globe-circling voyage to continue charting sea level, a vital indicator of global climate change. The mission will return a vast amount of new data that will improve weather, climate and ocean forecasts.
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.
Boosted by the influence of a larger climate event in the Pacific, one of the strongest La NiÃ±as in many years is slowly weakening but continues to blanket the Pacific Ocean near the equator, as shown by new sea-level height data collected by the U.S.-French Jason oceanographic satellite.
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.
Move over, Superman, with your X-ray vision. Marine scientists have now figured out a way to "see through" the ocean's surface and detect what's below, with the help of satellites in space.
Imagine a space tool so revolutionary it can determine the impact of climate change, monitor the melting of glaciers, discover invisible waves, predict the strength of hurricanes, conserve fish stocks and measure river and lake levels worldwide, among other scientific applications.
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.
