Sea surface temperature is the temperature of the top millimeter of the ocean's surface. A sea surface temperature anomaly (SSTA) represents how different the ocean temperature, at a particular location and time, is from the normal (or average) temperature for that place and time. These maps, showing sea surface temperature and sea surface temperature anomalies, reveal the progression of the strong 2015-16 El Nino event from January 1, 2015 to January 2, 2016. The sea surface temperature data are seven-day averages calculated using daily thermal data from the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument. Missing data have been filled with monthly-average data. The sea surface temperature anomaly data are seven-day averages calculated using the 5-kilometer Coral Reef Watch product produced by the National Oceanic and Atmospheric Administration. The data are based on observations from geostationary and polar-orbiting satellites. || ", "hits": 72 }, { "id": 30393, "url": "https://svs.gsfc.nasa.gov/30393/", "result_type": "Hyperwall Visual", "release_date": "2013-10-24T12:00:00-04:00", "title": "Monthly Sea Surface Temperature (Aqua/MODIS)", "description": "Sea-surface temperatures have a large influence on climate and weather. For example, ocean temperatures influence the development of tropical cyclones (hurricanes and typhoons), which draw energy from warm ocean waters to form and intensify. These maps show monthly sea-surface temperatures from July 2002 to the present, based on observations from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard NASA’s Aqua satellite. The satellite measures the temperature of the top millimeter of the ocean surface. The coolest waters appear as purple shades (approximately -2 degrees Celsius), while the warmest temperatures appear as yellow shades (45 degrees Celsius). Landmasses and the large area of sea ice around Antarctica appear in shades of gray, indicating no data were collected. The most obvious pattern shown in the time series is the year-round difference in sea surface temperatures between equatorial regions and the poles. Various warm and cool currents stand out even in monthly averages of sea surface temperature. A band of warm waters snakes up the East Coast of the United States and veers across the North Atlantic—known as the Gulf Stream. || ", "hits": 41 }, { "id": 10579, "url": "https://svs.gsfc.nasa.gov/10579/", "result_type": "Produced Video", "release_date": "2010-02-25T00:00:00-05:00", "title": "A Warming World Promo", "description": "This short video announces the launch of the \"A Warming World\" Web page on NASAs Global Climate Change Web site:http://climate.nasa.gov/warmingworld/A Warming World features videos, images, articles and interactive visuals that discuss rising global temperatures and the impact of greenhouse gases as the main contributor to modern climate trends.

Rising from the sea floor, the volcanic islands of the Galapagos are set on top of a large submarine platform. The main portion of the Galapagos platform is relatively flat and less than 1000 meters in depth. The steepest slopes are found along the western and southern flanks of the platform with a gradual slope towards the east. The interactions of the Galapagos and the oceanic currents create vastly different environmental regimes which not only isolates one part of the Archipelago from the other but allows penguins to live along the equator on the western part of the Archipelago and tropical corals around the islands to the north. The islands are relatively new in geologic terms with the youngest islands in the west still exhibiting periodic eruptions from their massive volcanic craters. || ", "hits": 35 }, { "id": 3388, "url": "https://svs.gsfc.nasa.gov/3388/", "result_type": "Visualization", "release_date": "2006-12-05T00:00:00-05:00", "title": "MODIS Sea Surface Temperature from 2002 to 2006", "description": "A recent study indicates there is a correlation between ocean nutrients and changes in sea surface temperature (SST).

Coral bleaching is a stress response that often occurs when the surrounding waters become too warm for the corals. In the stressful situation, the corals expel their brownish zooxanthellae and lose their color. Zooxanthellae are unicellular yellow-brown algae that make it possible for the corals to grow and reproduce quickly enough to create reefs. Without the zooxanthellae, the coral cannot obtain sufficient nourishment. If conditions remain difficult, the corals may die. Major coral bleaching incidents on the Great Barrier Reef in 1998 and 2002 led to widespread death of corals in some areas.

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": 22 }, { "id": 3343, "url": "https://svs.gsfc.nasa.gov/3343/", "result_type": "Visualization", "release_date": "2005-03-17T00:00:00-05:00", "title": "MODIS Sea Surface Temperature Data Shows Increased Temperatures in Southern Great Barrier Reef", "description": "Coral bleaching may be one of the greatest threats to the Great Barrier Reef.
