The latest image of sea-surface height measurements from the U.S./French Jason-1 oceanography satellite shows the Pacific Ocean remains locked in a strong, cool phase of the Pacific Decadal Oscillation, a large, long-lived pattern of climate variability in the Pacific associated with a general cooling of Pacific waters. The image also confirms that El Niño and La Niña remain absent from the tropical Pacific. The new image is available online at:...

Less than a month after launch, the NASA-French space agency Ocean Surface Topography Mission (OSTM)/Jason 2 oceanography satellite has produced its first complete maps of global ocean surface topography, surface wave height and wind speed. The new data will help scientists monitor changes in global sea level and the distribution of heat in the ocean. This information is used to monitor climate change and ocean circulation, and to enable more accurate weather, ocean and climate forecasts. The...

For humans in the path of destructive hurricanes and tsunamis, an accurate warning of the pending event is critical for damage control and survival. Such warnings, however, require a solid base of scientific observations, and a new satellite is ready for the job. The Ocean Surface Topography Mission (OSTM)/Jason 2 adds to the number of eyes in the sky measuring sea surface and wave heights across Earth's oceans. The increased coverage will help researchers improve current models for...

Imagine the lives that could be saved from flash floods and drought, the millions of dollars in fuel costs that could be avoided for fishing vessels, and the homes that could be spared from the effects of coastline erosion if only scientists could more accurately predict the dynamics of Earth's often unpredictable oceans. Armed with increasingly more accurate forecasts, weather services in countries across the globe are improving time-sensitive warnings of cyclones, flooding and high sea...

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. Satellite ocean observations are a standard part of marine operations around the world. Keeping track of local...

Ocean tides and currents across the globe still hold within their watery grasp the key to unanswered questions about our planet. 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: How does ocean circulation vary from season to season, from year to year and from decade to decade? How much can the ocean change from natural and...

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. With a thunderous roar and fiery glow, the Ocean Surface Topography Mission/Jason 2 satellite arced through the blackness of an early central coastal California morning at 12:46...

In economics, there's a metaphor that says "a rising tide lifts all boats," meaning overall improvement in the economy benefits everyone. While that's a good thing in economics, when it comes to our oceans, rising seas are a growing problem for all of us.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. Melting ice from Greenland and Antarctica could raise sea level more than one meter (three feet)...

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.The Ocean Surface Topography Mission (OSTM)/Jason 2 is a partnership of NASA, the National Oceanic and Atmospheric Administration (NOAA), the French Space Agency Centre National d'Etudes...
