In a city where sea level is of particular significance, a scientific conference on the radar that records sea-surface height will be held in September. The deadline for abstract submissions for the symposium in Venice, Italy, on two decades of radar altimetry is fast approaching. The ℠20 Years of Progress in Radar Altimetry´ Symposium will be held at the Venice Convention Centre Palazzo del Casinó from 24 to 29 September 2012. Organized in collaboration with the...

Repeating La Niña Hitting Its Peak: NASA
2012-01-21 04:27:40

La Niña, "the diva of drought," is peaking, increasing the odds that the Pacific Northwest will have more stormy weather this winter and spring, while the southwestern and southern United States will be dry. Sea surface height data from NASA's Jason-1 and -2 satellites show that the milder repeat of last year's strong La Niña has recently intensified, as seen in the latest Jason-2 image of the Pacific Ocean shown above. The image is based on the average of...

Image 1 - CryoSat Rides New Waves
2011-12-23 04:10:38

ESA´s CryoSat mission has been gathering detailed information on the thickness of Earth´s ice since its launch in 2010. Through international collaboration, this state-of-the-art mission is soon to be used to monitor conditions at sea for marine forecasting. CryoSat was built to measure tiny variations in the thickness of Earth´s ice. As a result, the mission is providing scientists with the data they need to help improve our understanding of the relationship between ice,...

Image 1 - Japanese Devastation The Result Of Merging Waves
2011-12-06 09:57:05

[ Watch the Video ] Researchers from NASA and Ohio State University have discovered that the deadly tsunami generated from the March 2011 Tohoku-Oki earthquake that devastated northeastern Japan resulted from merging waves, causing the killer tsunami to double in intensity over ocean ridges, and then amplifying its power upon landfall. Data taken from NASA and European radar satellites captured at least two wave fronts during the events that day. The fronts merged to form a single, more...

  An Update from NASA's Sea Level Sentinels: Like mercury in a thermometer, ocean waters expand as they warm. This, along with melting glaciers and ice sheets in Greenland and Antarctica, drives sea levels higher over the long term. For the past 18 years, the U.S./French Jason-1, Jason-2 and Topex/Poseidon spacecraft have been monitoring the gradual rise of the world's ocean in response to global warming. While the rise of the global ocean has been remarkably steady for most of...

The tropical Pacific Ocean has transitioned from last winter's El Niño conditions to a cool La Niña, as shown by new data about sea surface heights, collected by the U.S-French Ocean Surface Topography Mission (OSTM)/Jason-2 oceanography satellite. This OSTM/Jason-2 image of the Pacific Ocean is based on the average of 10 days of data centered on Sept. 3, 2010. A new image depicts places where the Pacific sea surface height is higher (warmer) than...

A relatively new type of El Niño, which has its warmest waters in the central-equatorial Pacific Ocean, rather than in the eastern-equatorial Pacific, is becoming more common and progressively stronger, according to a new study by NASA and NOAA. The research may improve our understanding of the relationship between El Niños and climate change, and has potentially significant implications for long-term weather forecasting. Lead author Tong Lee of...

Scientists and agencies monitoring the oil spill in the Gulf of Mexico are keeping a wary eye on changes in the nearby Loop Current, a warm ocean current that is part of the Gulf Stream. Beginning as a large flow of warm water from the Caribbean, the Loop Current heads up into the eastern part of the Gulf of Mexico and then turns south before finally moving out through the Straits of Florida and northward into the Gulf Stream. Deep and fast moving, the Loop Current often breaks off and forms...

Since May 2009, the tropical Pacific Ocean has switched from a cool pattern of ocean circulation known as La Niña to her warmer sibling, El Niño. This cyclical warming of the ocean waters in the central and eastern tropical Pacific generally occurs every three to seven years, and is linked with changes in the strength of the trade winds. El Niño can affect weather worldwide, including the Atlantic hurricane season, Asian monsoon...

Satellites that were designed to measure sea level over the world's oceans can serve a valuable purpose over land, a new study has found. Researchers used NASA's TOPEX/Poseidon satellite and the European Space Agency's ENVISAT satellite to measure the height and extent of flooding in North America, South America, and Asia. The study shows that satellites can supplement the measurements that the United States Geological Survey (USGS) gathers from flood gauges on the ground -- at little or no...

jument
  • A beast of burden; also, a beast in general.
'Jument' ultimately comes from the Latin 'jugum,' yoke.
