            "title": "Aqua Satellite and MODIS Swath",
            "description": "NASA's Aqua satellite was launched on May 4, 2002 with six Earth-observing instruments on board. 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. 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. || ",

            "description": "Coral bleaching may be one of the greatest threats to the Great Barrier Reef. 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. Researchers in the Barrier reef of Australia are using NASA's resources to help identify troubled coral. Currently, the most severe coral bleaching occurs over inshore reefs where the Sea Surface Temperatures are showing increased temperatures. || ",

            "description": "The earliest technique for measuring Sea Surface Temperature (SST) was dipping a thermometer into a bucket of water. 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. || ",

However, from 1997 to 2003, the glacier has begun to recede again, this time almost doubling in speed. The finding is important for many reasons. For starters, as more ice moves from glaciers on land into the ocean, it raises sea levels. Jakobshavn Isbrae is Greenland's largest outlet glacier, draining 6.5 percent of Greenland's ice sheet area. The ice stream's speed-up and near-doubling of ice flow from land into the ocean has increased the rate of sea level rise by about .06 millimeters (about .002 inches) per year, or roughly 4 percent of the 20th century rate of sea level increase.  This animation shows the recession for three years, from 2001 through 2003.

On the way, the trajectory of the spacecraft took it past Venus once and Earth twice. Galileo took the Earth images in this animation just after the first flyby of the Earth, on December 11 and 12, 1990. This six-hour sequence of images taken two minutes apart clearly shows how the Earth looks from space and how fast (or slow) the cloud features change when looked at from a distance. The path of the sun can be seen crossing Australia by its reflection in the nearby ocean, and the terminator region between night and day can be seen moving across the Indian Ocean. In the original images, the Earth's rotation is so dominant that cloud movement is hard to see, but these images have been mapped to the Earth is such a way that a viewer can watch just the clouds move in the ocean around Antarctica or across the Australian land mass. In this animation, New Zealand can ony be seen as a stationary disturbance under a moving cloud bank. The black area with the sharp boundary to the north and east of Australia is the side of the Earth that could not be seen from Galileo's position. || ",

Using a collection of satellite-based observations, scientists and visualizers stitched together months of observations of the land surface, oceans, sea ice, and clouds into a seamless, true-color mosaic of every square kilometer (0.386 square mile) of our planet. Much of the information contained in this image came from a single remote-sensing device-NASA's Moderate Resolution Imaging Spectroradiometer, or MODIS. Flying over 700 km above the Earth onboard the Terra satellite, MODIS provides an integrated tool for observing a variety of terrestrial, oceanic, and atmospheric features of the Earth. The land and coastal ocean portions of these images are based on surface observations collected from June through September 2001 and combined, or composited, every eight days to compensate for clouds that might block the sensor's view of the surface on any single day. Two different types of ocean data were used in these images: shallow water true color data, and global ocean color (or chlorophyll) data. Topographic shading is based on the GTOPO 30 elevation data set compiled by the U.S. Geological Survey's EROS Data Center. || ",
