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.

Density drives the pattern of deep ocean currents, and ocean currents drive global climate.

The SeaWiFS instrument is carried aboard the satellite OrbView-2, providing important information about the oceans, the land, and the life within them. On land, the dark greens show where there is abundant vegetation and tans show relatively sparse plant cover. In the oceans, red, yellow, and green pixels show dense phytoplankton blooms, those regions of the ocean that are the most productive over time, while blues and purples show where there is very little of the microscopic marine plants called phytoplankton. 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.

Carbon makes up Earth's plants and animals, and is also stored in the ocean, the atmosphere, and the crust of the planet. A carbon atom could spend millions of years moving through Earth in a complex cycle. This conceptual animation provides an illustration of the various parts of the Carbon cycle. Purple arrows indicate the uptake of Carbon; yellow arrows indicate the release of Carbon. On land, plants remove carbon from the atmosphere through photosynthesis. Animals eat plants and either breath out the carbon, or it moves up the food chain. When plants and animals die and decay, they transfer carbon back to the soil. Moving offshore, the ocean takes up carbon through physical and biological processes. At the ocean's surface, carbon dioxide from the atmosphere dissolves into the water. Tiny marine plants called phytoplankton use this carbon dioxide for photosynthesis. Phytoplankton are the base of the marine food web. After animals eat the plants, they breathe out the carbon or pass it up the food chain. Sometimes phytoplankton die, decompose, and are recycled in the surface waters. Phytoplankton can also sink to the bottom of the ocean, where they become buried in marine sediment. Over long time scales, this process has made the ocean floor the largest reservoir of carbon on the planet. In a process called upwelling, currents bring cold water containing carbon up to the surface. As the water warms, the carbon is then be released as a gas back into the atmosphere, continuing the carbon cycle. Carbon is found in the atmosphere as Carbon dioxide, which is a greenhouse gas. Greenhouse gases act like a blanket, and trap heat in the atmosphere. In the past two centuries, humans have increased atmospheric carbon dioxide by more than 30%, by burning fossil-fuels and cutting down forests. || ", "hits": 385 }, { "id": 10495, "url": "https://svs.gsfc.nasa.gov/10495/", "result_type": "Produced Video", "release_date": "2009-10-09T00:00:00-04:00", "title": "Marine Food Web", "description": "This conceptual animation illustrates some of the ecological pathways between species within the marine ecosystem.

Aqua circles the Earth every 99 minutes and is in a polar orbit, passing within ten degrees of each pole on every orbit. The orbit is sun-synchronous, meaning that the satellite always passes over a particular part of the Earth at about the same local time each day. 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.

A check up of the Earth's planetary health reveals that the lowest rung in the ocean food chain is shrinking. For the past 20 years (early 1980s to present), phytoplankton concentrations declined as much as 30 percent in northern oceans. Scientists from NASA, the National Oceanic and Atmospheric Administration (NOAA), and Oregon State University say warmer ocean temperatures and low winds may be depriving the tiny ocean plants of necessary nutrients. However, they still do not know if the loss of phytoplankton is a long-term trend or a climate oscillation. Scientists can monitor ocean and planetary health through phytoplankton. Since the whole ocean food chain depends on the health and productivity of phytoplankton, a significant change could indicate a shift in our climate. Phytoplankton consists of many diverse species of microscopic free-floating ocean plants that form the base of the ocean's food chain. These plants thrive on sunlight and nutrients. Limit either one and phytoplankton will not grow. This animation shows the Multivariate ENSO Index (MEI) in red and the net primary production NPP anomaly in units of Tgrams carbon per month in green. The MEI is a multivariate index that incorporates sea level pressure, surface zonal and meridional wind components, sea surface temperature, surface air temperature, and cloudiness (Wolter and Timlin, 1998). The MEI index is calculated for the tropical Pacific (i.e., between 10 degrees North and 10 degrees South, from Asia to the Americas) with units of kg m-3. The Net Primary Production (NPP) data was generated from the Vertically Generalized Production Model (VGPM). The VGPM data set is available at the following URL: http://web.science.oregonstate.eduocean.productivity/ .

The first automated technique for determining SST was accomplished by measuring the temperature of water in the intake port of large ships. A large network of coastal buoys in U.S. waters is maintained by the National Data Buoy Center (NDBC). Since about 1990, there has also been an extensive array of moored buoys maintained across the equatorial Pacific Ocean designed to help monitor and predict the El Niño phenomenon. Since the 1980s satellites have been increasingly utilized to measure SST and have provided an enormous leap in our ability to view the spatial and temporal variation in SST. The satellite measured SST provides both a synoptic view of the ocean and a high frequency of repeat views, allowing the examination of basin-wide upper ocean dynamics not possible with ships or buoys. For example, a ship traveling at 10 knots (20 km/h) would require 10 years to cover the same area a satellite covers in two minutes.This animation uses SST data taken at nighttime from the MODIS/Aqua and MODIS/Terra satellites. This data has many important applications that permit scientists to use ocean temperatures to observe ocean circulation and locate major ocean currents. Ocean current analysis can facilitate ocean transportation. Additionally, by using SST, scientists can monitor changes in ocean temperatures and relate these to weather and climate changes like coral bleaching around the Great Barrier Reef. Finally, the SST changes have many important biological implications for hospitable/inhospitable conditions for many organisms including species of plankton, seagrasses, shellfish, fish, coral, and mammals. || ", "hits": 26 }, { "id": 3342, "url": "https://svs.gsfc.nasa.gov/3342/", "result_type": "Visualization", "release_date": "2005-03-17T00:00:00-05:00", "title": "IKONOS and Aqua MODIS Imagery of Southern Great Barrier Reef", "description": "Coral bleaching may be one of the greatest threats to the Great Barrier Reef.

This warm water trapped the ocean nutrients that normally come to the surface in the upwelling cold water, leading to a drastic decrease in phytonplankton and other ocean life in the region. The unique Galapagos ecosystem was severely affected and many species, including sea lions, seabirds, and barracudas, suffered a very high mortality level. During the second week of May, 1998, the ocean temperatures plummeted 10 degrees in one day, and the ocean productivity exploded with large phytoplankton blooms. After this time, many species recovered very rapidly and the land species started to reproduce immediately.
