Latest Sea surface height Stories
The tropical Pacific Ocean has transitioned from last winter's El NiÃ±o conditions to a cool La NiÃ±a, as shown by new data about sea surface heights, collected by the US-French Ocean Surface Topography Mission (OSTM)/Jason-2 oceanography satellite.
The latest image of Pacific Ocean sea surface heights from the NASA/European Ocean Surface Topography Mission/Jason-2 oceanography satellite, dated June 11, 2010, shows that the tropical Pacific has switched from warm (red) to cold (blue) during the last few months.
Since May 2009, the tropical Pacific Ocean has switched from a cool pattern of ocean circulation known as La NiÃ±a to her warmer sibling, El NiÃ±o.
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.
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.
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.
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, 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.
