Prospects have been fading for an El Niño event in 2014, but now there's a glimmer of hope for a very modest comeback.
Every ten days, the NASA/French Space Agency Jason-2 satellite maps all the world's oceans, monitoring changes in sea surface height, a measure of heat in the upper layers of the water. Because our planet is more than 70% ocean, this information is crucial to global forecasts of weather and climate.
NASA and the French space agency Centre National d'Études Spatiales (CNES) have agreed to jointly build, launch, and operate a spacecraft to conduct the first-ever global survey of Earth's surface water and to map ocean surface height with unprecedented detail.
Based on satellite data, experts have found near-normal sea-surface height conditions across the equatorial Pacific Ocean, indicative of a so called “La Nada” event.
A unique and complex set of circumstances came together over Australia from 2010 to 2011 to cause Earth’s smallest continent to be the biggest contributor to the observed drop in global sea level rise during that time
NASA mission controllers recently lost contact with the Jason-1 satellite, and the space agency has decided to abandon this satellite and focus attention on the other two satellites currently orbiting Earth.
Thirty-five years ago this week, NASA's Jet Propulsion Laboratory launched an experimental satellite called Seasat, with the mission to study Earth and its seas. An unexpected malfunction ended the mission after just 106 days, leading some to look on the satellite as a failure.
Three NASA-built instruments that are integral components of the next in a series of U.S./European ocean altimetry satellites have arrived in France for integration with their spacecraft in preparation for a 2015 launch.
Scientists have gathered in the 'floating city' this week to talk about radar altimetry – measuring the heights of the global sea surface, freshwater bodies, land and ice using spaceborne sensors.
