Alkalinity is a measure of the ability of seawater to neutralize acids. This visualization shows monthly surface total alkalinity (TA) from August 2011 to May 2015 as derived using data from NASA’s Aquarius mission. Utilization of Aquarius data allows unprecedented global mapping of surface TA as it correlates strongly with salinity and to a lesser extent with temperature.For the first time, Aquarius data are allowing scientists to observe changes in surface alkalinity over time. For example, they have found that the Northern Hemisphere has more spatial and monthly variability in total alkalinity and salinity, while less variability in Southern Ocean alkalinity is due to less salinity variability and upwelling of waters enriched in alkalinity. Increasing surface TA in subtropical regions from increasing salinity and temperature causes the saturation states of calcite and aragonite to decrease, i.e., enhanced dissolution. Thus, based on increasing TA in the subtropical regions over the past few decades, it is expected that it is becoming more difficult for calcifying organisms to make their shells. || ", "hits": 171 }, { "id": 30645, "url": "https://svs.gsfc.nasa.gov/30645/", "result_type": "Hyperwall Visual", "release_date": "2015-09-23T00:00:00-04:00", "title": "ENSO Sea Surface Temperature Anomalies: 2015-2016", "description": "Animation of Sea Surface Temperature Animaly from Dec 31, 2013 to present. || enso_ssta_2014-2016_print.jpg (1024x574) [225.9 KB] || enso_ssta_2014-2016.png (4104x2304) [6.5 MB] || enso_ssta_2014-2016_searchweb.png (320x180) [112.5 KB] || enso_ssta_2014-2016_thm.png (80x40) [8.0 KB] || enso_ssta_20131201-20160217_720p15.webm (1280x720) [28.8 MB] || enso_ssta_20131201-20160217_720p15.mp4 (1280x720) [221.0 MB] || enso_ssta_20131201-20160217_1080p15.mp4 (1920x1080) [360.9 MB] || enso_ssta_20131201-20160217_30645.key [223.5 MB] || enso_ssta_20131201-20160217_30645.pptx [221.1 MB] || enso_ssta_20131201-20160217_2304p15.mp4 (4104x2304) [896.9 MB] || ", "hits": 1503 }, { "id": 30550, "url": "https://svs.gsfc.nasa.gov/30550/", "result_type": "Hyperwall Visual", "release_date": "2014-11-19T22:00:00-05:00", "title": "ENSO Sea Surface Temperature Anomalies: 2009-2010", "description": "Animation of SSTA shows the evolution of the 2009-2010 ENSO. || enso_2009-2010_still_print.jpg (1024x574) [173.4 KB] || enso_2009-2010_still_thm.png (80x40) [7.8 KB] || enso_2009-2010_still_web.jpg (319x179) [27.4 KB] || enso_2009-2010_still_searchweb.png (320x180) [103.4 KB] || enso_2009-2010_720p.mp4 (1280x720) [71.7 MB] || enso_2009-2010_720p.webmhd.webm (960x540) [21.7 MB] || enso_2009-2010_540p.webm (960x540) [15.0 MB] || enso_2009-2010_1080p.mp4 (1920x1080) [111.6 MB] || enso_2009-2010_360p.mp4 (640x360) [30.4 MB] || enso_2009-2010.pptx [71.9 MB] || enso_2009-2010.key [74.4 MB] || enso_2009-2010_2304p.mp4 (4096x2304) [348.1 MB] || ", "hits": 150 }, { "id": 30551, "url": "https://svs.gsfc.nasa.gov/30551/", "result_type": "Hyperwall Visual", "release_date": "2014-11-19T16:00:00-05:00", "title": "ENSO Sea Surface Temperature Anomalies: 1997-1998", "description": "Sea Surface Temperature Anomaly during the the 1997-1998 ENSO event. || enso_1997-1998_still_print.jpg (1024x574) [175.7 KB] || enso_1997-1998_still.png (4104x2304) [5.2 MB] || enso_1997-1998_still_searchweb.png (320x180) [104.0 KB] || enso_1997-1998_still_web.png (320x179) [103.8 KB] || enso_1997-1998_still_thm.png (80x40) [7.9 KB] || enso_1997-1998_720p.mp4 (1280x720) [76.7 MB] || enso_1997-1998_540p.webm (960x540) [15.0 MB] || enso_1997-1998_1080p.mp4 (1920x1080) [116.4 MB] || enso_1997-1998_360p.mp4 (640x360) [32.6 MB] || enso_1997-1998.pptx [76.9 MB] || enso_1997-1998.key [79.5 MB] || enso_1997-1998_2304p.mp4 (4096x2304) [360.4 MB] || ", "hits": 2586 }, { "id": 30486, "url": "https://svs.gsfc.nasa.gov/30486/", "result_type": "Hyperwall Visual", "release_date": "2014-02-28T00:00:00-05:00", "title": "Sea Surface Temperature in the Eastern Pacific", "description": "This animation from Jan 2011 to Dec 2013 shows high resolution sea surface temperature (SST) in the Eastern Pacific off Central America.
