Salinity changes are linked to the cycling of freshwater around the planet and influence ocean circulation.The new map, which shows a tapestry of salinity patterns, demonstrates Aquarius' ability to detect large-scale salinity distribution features clearly and with sharp contrast. The map is a composite of the data since Aquarius became operational on Aug. 25. The mission was launched June 10 from Vandenberg Air Force Base in California. Aquarius/SAC-D is a collaboration between NASA and Argentina's space agency, Comision Nacional de Actividades Espaciales (CONAE).To produce the map, Aquarius scientists compared the early data with ocean surface salinity reference data. Although the early data contain some uncertainties, and months of additional calibration and validation work remain, scientists are impressed by the data's quality.The map shows several well-known ocean salinity features such as higher salinity in the subtropics; higher average salinity in the Atlantic Ocean compared to the Pacific and Indian Oceans; and lower salinity in rainy belts near the equator, in the northernmost Pacific Ocean and elsewhere. These features are related to large-scale patterns of rainfall and evaporation over the ocean, river outflow and ocean circulation. Aquarius will monitor how these features change and study their link to climate and weather variations.Other important regional features are evident, including a sharp contrast between the arid, high-salinity Arabian Sea west of the Indian subcontinent, and the low-salinity Bay of Bengal to the east, which is dominated by the Ganges River and south Asia monsoon rains. The data also show important smaller details, such as a larger-than-expected extent of low-salinity water associated with outflow from the Amazon River.Aquarius was built by NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Calif., and the Goddard Space Flight Center in Greenbelt, Md., for NASA's Earth Systems Science Pathfinder Program.

For most of the world's oceans, the most important things that influence its color are phytoplankton. Phytoplankton are very small, single-celled plants, generally smaller than the size of a pinhead that contain a green pigment called chlorophyll. All plants (on land and in the ocean) use chlorophyll to capture energy from the sun and through the process known as photosynthesis convert water and carbon dioxide into new plant material and oxygen. Although microscopic, phytoplankton can bloom in such large numbers that they can change the color of the ocean to such a degree that we can measure that change from space. The basic principle behind the remote sensing of ocean color from space is this: the more phytoplankton in the water, the greener it is...the less phytoplankton, the bluer it is.

Aqua always crosses the equator from south to north at about 1:30 PM local time. One of the instruments on Aqua, MODIS, measures 36 spectral frequencies of light reflected off the Earth in a 2300-kilometer wide swath along this orbit, so that MODIS measures almost the entire surface of the Earth every day.The first animation shows the Aqua satellite orbiting for one day, August 27, 2005, showing a set of MODIS measurements taken that day that have been processed to look like a a true-color image of the Earth. Notice that MODIS only takes data during the dayside part of the orbit because it measures reflected light from the Sun, and that there is a bright band of reflected sunlight in the center of swaths over the ocean. Also visible in this animation are Hurricane Katrina, just to the west of Florida in the Gulf of Mexico, and Typhoon Talim, in the western Pacific between Japan and New Guinea.The second animation spans five days of Aqua orbits, from August 27, 2005 through August 31, 2005. For this animation, the orbits and data are shown over an Earth image that shows the day and night parts of the Earth at each time of the animation. The daylight part of the Earth is a cloud-free MODIS composite, while the nighttime regions show the 'city lights', the Earth's stable light sources. During the first day, August 27, the Aqua satellite is shown with a red line indicating the orbit of the satellite. Since the Earth's surface is stationary in this animation, the satellite orbit moves westward with the sun. During the second day, August 28, the most recent observation swath is shown in addition to the satellite orbit line. In this way , the drift of th orbit relative to the observations is illustrated. Starting with the third day, August 29, the orbit line disappears and the observation swaths accumulate. The observations cover the Earth during the third day except for small gaps at the equator, which are filled in during the fourth day, August 30. The animation continues to show the MODIS observations through August 31, the fifth day.The third animation shows the same composition as the second one, but the point of view has changed to that of the Sun. In this animation, the Earth rotates and the orbit is stationary. At this date, the North Pole of the Earth is tilted towards the Sun and in daylight, while the South Pole is tilted away and is in darkness. || ", "hits": 113 }, { "id": 3321, "url": "https://svs.gsfc.nasa.gov/3321/", "result_type": "Visualization", "release_date": "2006-04-17T00:00:00-04:00", "title": "Aqua MODIS True Color Progression during Hurricane Katrina", "description": "The Aqua satellite orbits the Earth every 99 minutes in a polar, sun-synchronous orbit.
