show the saltiness, also known as “salinity,” of the ocean surface. The ocean's salinity is key to studying the water cycle and ocean circulation, both of which are important to Earth's climate.<\/p>\r\n<p>Throughout Earth's history, the weathering of rocks has delivered minerals, including salt, into the ocean. Over decades, this amount of salt in ocean basins has been relatively stable. The water cycle operates on much faster time scales, however, causing changes in salinity patterns. For example, freshwater enters the ocean from rivers, melting ice, rain, and snow. These processes tend to make the ocean less salty. On the other hand, processes that cause freshwater to exit the ocean—such as evaporation and formation of sea ice—make the ocean saltier.<\/p>\r\n<p>Differences in salinity play a major role in moving seawater around the globe. Below the wind-blown ocean surface, salinity and temperature drive circulation by controlling the “density” (mass per unit volume) of seawater. The weight of dissolved salt increases water's density and when salinities are equal, colder water is denser than warmer water. In addition to moving salt and water, density-driven circulation is crucial to moving heat around our planet. The movement of heat by our ocean—for example, from the equator to the poles—is crucial to keeping Earth's climate “just right.”<\/p>\r\n<p>These maps are made from satellite observations which cover the globe every week. The black areas show where data were not available, usually close to the coasts where strong signals from the land can interfere with accurate measurements.<\/p>","DESC_INT":"<p>Although everyone knows that seawater is salty, few know that even small variations in ocean surface salinity (i.e., concentration of dissolved salts) can reveal important information about our planet. Over long periods of time, the amount of salt in Earth's ocean basins has remained relatively fixed. Short-term variations in salinity patterns\u2014seen in weekly maps from NASA's Aquarius satellite instrument\u2014reflect changes in the water cycle and ocean circulation, both of which are linked to climate.<\/p>\r\n\r\n<p>Interpreting salinity patterns begins with knowing how water cycles among the ocean's physical states: liquid, vapor, and ice. As a liquid, water dissolves rocks and reacts with emissions from hydrothermal vents, creating a complex solution of mineral salts in our ocean basins. In other states\u2014vapor and ice\u2014water and salt are incompatible. As a result, evaporation of ocean water and formation of sea ice both increase the salinity of the ocean. However, these \u201csalinity-raising\u201d factors are counterbalanced by processes that decrease salinity such as the continuous input of fresh water from rivers, precipitation of rain and snow, and melting of ice. Since about 86% of global evaporation and 78% of global precipitation occur over the ocean, monitoring salinity is key to understanding Earth's global water cycle.<\/p>\r\n\r\n<p>Surface winds drive currents in the upper ocean. Deep below the surface, ocean circulation is primarily controlled by changes in seawater density (mass per unit volume), which depends on salinity and temperature. The weight of dissolved salt increases water's density. Likewise, lower temperature increases seawater's density. In some regions, such as the North Atlantic near Greenland, cold high-salinity surface waters can become dense enough to sink to great depths. This type of density-controlled circulation interconnects all ocean basins, transporting not only salt and water but also the heat that affects Earth's climate.<\/p>\r\n\r\n<p>Recent studies suggest that seawater is becoming fresher in high latitudes and tropical areas dominated by rain, while in sub-tropical high evaporation regions, waters are getting saltier. In addition to the direct impact of an apparent \u201cacceleration\u201d of the water cycle, such changes could affect how excess heat from a warning climate is absorbed and transported by the oceans. Thus, monitoring changes in ocean surface salinity is helping scientists better recognize connections between the water cycle and ocean circulation in our changing climate.<\/p>","DESC_ADV":"Aquarius Level 3 sea surface salinity (SSS) standard mapped image data contains gridded 1 degree spatial resolution SSS averaged over daily, 7 day, monthly, and seasonal time scales. These images show the sea surface salinity product for version 4.0 of the Aquarius data set from the AQUARIUS\/SAC-D mission. The monthly images are made from the smoothed version of the dataset. The Aquarius instrument is onboard the AQUARIUS\/SAC-D satellite, a collaborative effort between NASA and the Argentinian Space Agency Comision Nacional de Actividades Espaciales (CONAE). The instrument consists of three radiometers in push broom alignment at incidence angles of 29, 38, and 46 degrees incidence angles relative to the shadow side of the orbit. Footprints for the beams are: 76 km (along-track) x 94 km (cross-track), 84 km x 120 km and 96km x 156 km, yielding a total cross-track swath of 370 km. The radiometers measure brightness temperature at 1.413 GHz in their respective horizontal and vertical polarizations (TH and TV).

The black areas show where data were not available, usually close to the coasts where strong signals from the land can interfere with accurate measurements.</p> </span> </div> </div> <div class="bot"></div> </div> </div> <div class="col-r"> <div class="box analyze"> <div class="mid"> <div class="side-hd"> <h3> <span class="arr"></span> <span class="l"></span> <a href="javascript:;" onclick="addSceneImage('1690566','Sea Surface Salinity (1 month, 2011-15) May 2015', 'https://web.archive.org/web/20200926095144/https://neo.sci.gsfc.nasa.gov/servlet/');" id="btn-analyze-image" class="btn-analyze-image hover">Add to Analysis</a> </h3> </div> <div class="side-post"> <div class="details"> <p>Currently viewing:</p> <h3><span id="download-date">May 2015</span></h3> <p><strong><a id="permalink" class="permalink" href="view.php?datasetId=AQUARIUS_SSS_M&date=2015-05-01">Permalink</a></strong></p> </div> <div class="downloads"> <h3>Downloads <a class="fancyhelp btn-info" href="/web/20200926095144/https://neo.sci.gsfc.nasa.gov/parts/help_download.php">info</a></h3> <form> <table> <tr> <th>File Type:</th> <td> <select class="updateFormat"> <option value="JPEG" selected="selected"> JPEG </option> <option value="PNG"> PNG </option> <option value="FLOAT.TIFF"> GeoTIFF (floating point) </option> <option value="TIFF"> GeoTIFF (raster) </option> <option value=""> ----- </option> <option value="CSV"> CSV </option> <option value="SS.CSV"> CSV for Excel </option> <option value="KMZ"> Google Earth </option> </select> </td> </tr> <tr class="color-option"> <th colspan="2"> <input type="radio" name="colorbar-select" class="updateColor" id="colorbar-color" value="rgb" checked> <label for="colorbar-color">Color</label> <input type="radio" name="colorbar-select" class="updateColor" id="colorbar-grayscale" value="gs"> <label for="colorbar-grayscale">Grayscale</label> </th> </tr> <tr class="size-option"> <th>1.0 degrees</th> <td><strong><a href="https://web.archive.org/web/20200926095144/https://neo.sci.gsfc.nasa.gov/servlet/RenderData?si=1690566&cs=rgb&format=JPEG&width=360&height=180" class="download" target="_blank">360 x 180</a></strong> <a href="https://web.archive.org/web/20200926095144/https://neo.sci.gsfc.nasa.gov/servlet/RenderData?si=1690566&cs=rgb&format=JPEG&width=360&height=180" class="download download-link" target="_blank">download</a></td> </tr> <tr class="size-option"> <th>0.5 degrees</th> <td><strong><a href="https://web.archive.org/web/20200926095144/https://neo.sci.gsfc.nasa.gov/servlet/RenderData?si=1690566&cs=rgb&format=JPEG&width=720&height=360" class="download" target="_blank">720 x 360</a></strong> <a href="https://web.archive.org/web/20200926095144/https://neo.sci.gsfc.nasa.gov/servlet/RenderData?si=1690566&cs=rgb&format=JPEG&width=720&height=360" class="download download-link" target="_blank">download</a></td> </tr> <tr class="sscsv"> <th colspan="2"><strong><a href="https://web.archive.org/web/20200926095144/https://neo.sci.gsfc.nasa.gov/servlet/RenderData?si=1690566&cs=gs&format=SS.CSV&width=250&height=125" target="_blank">CSV for Excel older than 2007</a></strong> <a href="https://web.archive.org/web/20200926095144/https://neo.sci.gsfc.nasa.gov/servlet/RenderData?si=1690566&cs=rgb&format=JPEG&width=720&height=360" class="download download-link" target="_blank">download</a></th> </tr> </table> </form> <br/> <p><strong><a id="download-data" href="https://web.archive.org/web/20200926095144/ftp://podaac-ftp.jpl.nasa.gov/allData/aquarius/L3/mapped/V4/monthly/SCISM/2015/Q20151212015151.L3m_MO_SCISM_V4.0_SSS_1deg.bz2">Download Raw Data</a></strong> (<span id="data-size">262 KB</span>)</p> </div> <script> // update the download request format $('.updateFormat').change(function() { $('.download').each(function() { var format = $('.updateFormat option:selected').val();
