Rosalie Murphy, JPL Earth Science and Technology Directorate The ocean covers 71 percent of Earth's surface and affects weather over the entire globe. Hurricanes and storms that begin far out over the ocean affect people on land and interfere with shipping at sea. And the ocean stores carbon and heat, which are transported from the ocean to the air and back, allowing for photosynthesis and affecting Earth's climate. To understand all these processes, scientists need information about winds...

Hidden Cycles Of Sea Winds To Be Revealed By NASA's RapidScat
2014-07-08 03:19:00

NASA's Jet Propulsion Laboratory Ocean waves, the hot sun, sea breezes -- the right combination makes a great day at the beach. A different combination makes a killer hurricane. The complex interactions of the ocean and the air above it that can create such different outcomes are not yet fully known. Scientists would especially like to understand the role that the daily heat of the sun plays in creating winds. In a few months, NASA will send an ocean wind-monitoring instrument to a...

QuikScat's Eye On Ocean Winds Lives On After 15 Years
2014-06-20 03:55:48

Rosalie Murphy, NASA's Jet Propulsion Laboratory Today (June 19) marks the 15th anniversary of the launch of NASA's QuikScat, a satellite sent for a three-year mission in 1999 that continues collecting data. Built in less than 12 months, QuikScat has watched ocean wind patterns for 15 years and improved weather forecasting worldwide. Despite a partial instrument failure in 2009, it provides calibration data to international partners. On this anniversary, the mission's team is preparing...

Brett Smith for redOrbit.com - Your Universe Online The best chefs in the world can create a gourmet dish from leftover ingredients and NASA scientists have set out to show they can accomplish a similar feat though the ISS-RapidScat science mission. An abbreviated form of Rapid Scatterometer, ISS-RapidScat was fashioned from spare parts and put together on a relatively short time scale. The mission will monitor ocean winds from the International Space Station. Scientists study ocean...

Ocean Winds To Be Monitored From The International Space Station
2013-01-30 07:48:19

April Flowers for redOrbit.com - Your Universe Online NASA will launch the ISS-RapidScat instrument to the International Space Station (ISS) in 2014. Reusing hardware built to test parts of the QuikScat satellite, the new instrument will measure ocean-surface wind speed and direction. ISS-RapidScat will help improve weather forecasts here on Earth, including hurricane monitoring, and will further scientific understanding of how ocean-atmosphere interactions influence Earth's climate....

Amazon Rainforest Under Threat From Climate Change

April Flowers for redOrbit.com - Your Universe Online A megadrought that started in 2005 is still affecting a portion of the Amazon Rainforest twice the size of California, a new study led by NASA's Jet Propulsion Laboratory (JPL) finds. The results of this study, combined with the observed recurrences of droughts every few years and associated damage to forests in both the southern and western Amazon over the past decade, reveal that the rainforest might be showing the initial signs of...

A NASA analysis of satellite data has quantified, for the first time, the amount of older and thicker "multiyear" sea ice lost from the Arctic Ocean due to melting. Since the start of the satellite record in 1979, scientists have observed the continued disappearance of older "multiyear" sea ice that survives more than one summer melt season. Some scientists suspected that this loss was due entirely to wind pushing the ice out of the Arctic Basin -- a process that scientists refer to as...

NASA mission managers are assessing options for future operations of the venerable QuikScat satellite following the age-related failure of a mechanism that spins the scatterometer antenna. This spinning antenna had been providing near-real-time ocean- surface wind speed and direction data over 90 percent of the global ocean every day. In recent months, the QuikScat project team has been monitoring a pattern of increasing friction in the bearings that allow the antenna to spin, leading to...


Word of the Day
ween
  • To think; to imagine; to fancy.
  • To be of opinion; have the notion; think; imagine; suppose.
The word 'ween' comes from Middle English wene, from Old English wēn, wēna ("hope, weening, expectation"), from Proto-Germanic *wēniz, *wēnōn (“hope, expectation”), from Proto-Indo-European *wen- (“to strive, love, want, reach, win”).
