Latest Jason-1 Stories
Hurricanes aren't the only hazards spinning up in the Gulf of Mexico -- they have a liquid counterpart in the waters below called ocean eddies. Offshore industries, such as oil and gas companies, have to keep a weather eye on both. In a worst-case scenario, they could find themselves caught between the two. Satellite altimetry is helping government and industry manage those risks.
Scientists hope the new follow-on mission to the Jason 1 and Topex/Poseidon satellite missions, equipped with the latest high-tech instruments, will bring them closer to answering broad fundamental questions about the ocean.
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.
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.
For more than a decade space-based radar instruments have been routinely observing ocean surface phenomena including wind, waves, oil slicks, even the eyes of hurricanes. Now â€“ employing the same principle as police speed guns â€“ satellite radar has also begun to enable direct measurements of the speed of the moving ocean surface itself.
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.
