ESA’s SMOS And NASA’s Aquarius Missions Monitoring Ocean Salinity
2013-04-22 14:21:15

ESA [ Watch The Video Freshwater Plume From SMOS And Aquarius ] The saltiness of the oceans is being closely monitored from space by both ESA´s SMOS and NASA´s Aquarius missions, but in slightly different ways. By joining forces, researchers are exploiting these complementary missions to benefit climate science even further. Everyone knows that seawater is salty, but it isn´t that obvious that the concentration of salt — the salinity — of the surface waters...

Salt Levels In Draa Basin Groundwater A Detriment To Farming
2013-04-08 19:37:12

Brett Smith for redOrbit.com — Your Universe Online Arid but habitable regions around the world depend on limited water resources for drinking and crop irrigation. Any disruption or contamination of the water supply could be a major problem for a local population. The Draa Basin in Sub-Saharan Africa is one such region, as it has relied on runoff from Morocco's High Atlas Mountains. It has also been dammed and directed toward oases hundreds of miles to the south. A group of...

Salinity Levels In Atlantic Ocean Are Off The Chart, According To NASA Instrument

WATCH VIDEOS: [Aquarius Measuring Salty Seas 1] - [Aquarius Measuring Salty Seas 2] Lawrence LeBlond for redOrbit.com - Your Universe Online The salinity level of the world´s rivers, lakes and oceans has been a growing topic in response to global climate change. As NASA´s Aquarius instrument has shown previously, seasonal salinity has been on the rise in oceans all around the world. This year, the picture is no less striking, with deep shades of oranges and reds, at least in...

A Better Look At Salinity From SMOS
2012-10-01 08:26:12

Earth observation measurements shouldn´t be taken with a pinch of salt. ESA is comparing readings of sea-surface salinity from drifting floats to confirm the SMOS water mission´s measurements. Since its launch in 2009, ESA´s Soil Moisture and Ocean Salinity (SMOS) satellite has been helping us to understand the water cycle. As with any Earth observation mission, it is important to validate the readings acquired from space. This involves comparing the satellite data with...

Lee Rannals for redOrbit.com - Your Universe Online A new expedition is set to get a better picture of how salt content fluctuates in the ocean's upper layers, and how it shifts rainfall patterns. The NASA-sponsored expedition called the Salinity Processes in the Upper Ocean Regional Study (SPURS) will provided new data to help calibrate the salinity measurements NASA's Aquarius instrument has been collecting from space since August 2011. SPURS scientists will hop aboard the vessel...

WASHINGTON, Sept. 5, 2012 /PRNewswire-USNewswire/ -- A NASA-sponsored expedition is set to sail to the North Atlantic's saltiest spot to get a detailed, 3-D picture of how salt content fluctuates in the ocean's upper layers and how these variations are related to shifts in rainfall patterns around the planet. (Logo: http://photos.prnewswire.com/prnh/20081007/38461LOGO) The research voyage is part of a multi-year mission, dubbed the Salinity Processes in the Upper Ocean Regional Study...

As Ground Radars Switch Off, SMOS Satellite Measurements Improve
2012-07-04 15:13:20

Over a dozen radio signals that have hindered data collection on ESA´s SMOS water mission have been switched off. The effort also benefits satellites such as NASA´s Aquarius mission, which measures ocean salinity at the same frequency. We all know what happens when you place a cell phone too close to a speaker: seconds before the phone rings, that obnoxious buzz interrupts your favourite song. This is radio interference — an unwanted reception of radio signals. Not only...

NASA's Aquarius Yields Global Map Of Ocean Salinity
2011-09-23 04:39:30

   NASA's new Aquarius instrument has produced its first global map of the salinity of the ocean surface, providing an early glimpse of the mission's anticipated discoveries. Aquarius, which is aboard the Aquarius/SAC-D (Satelite de Aplicaciones Científicas) observatory, is making NASA's first space observations of ocean surface salinity variations - a key component of Earth's climate. Salinity changes are linked to the cycling of freshwater around the planet and...

Written by Rosemary Sullivant, NASA/JPL The breakthrough moment for oceanographer Gary Lagerloef, the principal investigator for NASA's new Aquarius mission, came in 1991. That's when he knew it would be possible to make precise measurements of ocean salinity from space. It has taken nearly two decades to turn that possibility into a reality. Lagerloef was looking at data collected by a NASA aircraft flying over the ocean off the coast of Maryland. It was testing a new radiometer, an...

When NASA's salt-seeking Aquarius instrument ascends to the heavens this June, the moon above its launch site at California's Vandenberg Air Force Base won't be in the seventh house, and Jupiter's latest alignment with Mars will be weeks in the past, in contrast to the lyrics of the song from the popular Broadway musical "Hair." Yet for the science team eagerly awaiting Aquarius' ocean surface salinity data, the dawning of NASA's "Age of Aquarius" promises revelations on how salinity is...

Soil Salinity
2013-04-01 11:15:13

Soil salinity is the salt content within the soil; the process of increasing the content of salt is known as salination. Salt is a natural element of water and soils. Salination can be a result of natural processes such as the gradual withdrawal of an ocean or mineral weathering. It can be caused by artificial processes such as irrigation as well. Soils that are affected by salt are a result of excess accumulation of salts, normally most obvious at the surface of the soil. Salts can be...
