PASADENA, Calif. "“ 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. The new satellite will study ocean circulation and the effect oceans have on weather, climate and how Earth is responding to global climate change. The Ocean Surface Topography Mission, called OSTM for short, will be flown on the Jason-2 spacecraft, which was transported on April...

Boosted by the influence of a larger climate event in the Pacific, one of the strongest La Niñas 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.This La Niña, which has persisted for the past year, is indicated by the blue area in the center of the image along the equator. Blue indicates lower than normal sea...

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. Both took advantage of something that sailors have been relying on since the launch of Topex/Poseidon in 1992"“maps of ocean currents made possible by ocean altimetry. The teams consulted with David Griffin, a research scientist with Australia's Commonwealth...

The tropical Pacific Ocean remains in the grips of a cool La Niña, as shown by new data of sea-level heights from mid-October of 2007, collected by the U.S-French Jason altimetric satellite. This La Niña, which has slowly strengthened for the past nine months, is indicated by the blue area in the center of the image along the equator. Blue indicates lower than normal sea level (cold water). "After eight very dry years on the Colorado River watershed...

JPL -- 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. "Topex/Poseidon revolutionized the study of Earth's oceans, providing the first continuous, global coverage of ocean surface topography and allowing us to see important week-to-week oceanic variations," said Dr. Mary Cleave, associate administrator...

NASA -- 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. Other factors that contribute to sea level change are the amount of water stored in lakes and reservoirs and the rising and falling of land in coastal regions. "From the Mississippi Delta to the Maldives Islands off the coast of India to the...

JPL -- 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. The measurements are of tremendous value to researchers worldwide and will aid our understanding of these events. U.S. and French teams working in parallel with altimetry data from the joint NASA/French Space Agency Jason and Topex/Poseidon oceanography satellites have...


Word of the Day
mallemaroking
  • Nautical, the visiting and carousing of sailors in the Greenland ships.
This word is apparently from a confusion of two similar Dutch words: 'mallemerok,' a foolish woman, and 'mallemok,' a name for some persons among the crew of a whaling vessel.
