Sequence of Clouds, Snow Cov

| Title |
Sequence of Clouds, Snow Cover, Sea Ice, Sea Surface Temperature and Biosphere |
| Abstract |
This animation is part of an NSF-funded, international project, Exploring Time. The two-hour television special, broadcast on the Discovery Channel in the spring of 2007, explores how the world changes over different timescales ... from billionths of seconds to billions of years. This animation portrays a variety of remotely sensed data elements at different temporal resolutions. Initially, the animation shows cloud cover in motion over North America in half-hour increments from Nov. 26 to Dec. 7, 2005. The temporal pace quickens to show a 5-day moving average of daily MODIS snow cover along with daily AMSR-E sea ice from Dec. 7, 2005 to Mar. 15, 2006. As the view swings south over the Gulf of Mexico, the AMSR-E Sea Surface Temperature reveals warming ocean temperatures from March through August, 2006. As it passes over the Atlantic Ocean, the biosphere fades into view, showing both chlorophyll concentration in the ocean along with Normalized Difference Vegetation Index over the land areas. The biosphere animates over time while the view pans over northern Africa and Europe, showing data collected from September 2002 through February 2006. This program was also broadcast in Japan through a partnership with the NHK international broadcasting service and in France through a partnership with the ARTE television network. |

Loop of AMSR-E Daily Arctic
…
| Title |
Loop of AMSR-E Daily Arctic Sea Ice from Aug 2005 to Aug 2006 |
| Abstract |
Sea ice is frozen seawater floating on the surface of the ocean. Some sea ice is permanent, persisting from year to year, and some is seasonal, melting and refreezing from season to season. Sea ice is almost always in motion, reacting to ocean currents and to winds. The AMSR-E instrument on the Aqua satellite acquires high resolution measurements of the 89 GHz brightness temperature near the poles. Because this is a passive microwave sensor and independent of atmospheric effects, this sensor is able to observe the entire polar region every day, even through clouds and snowfalls. This animation of AMSR-E 89 GHz brightness temperature in the northern hemisphere during late 2005 and early 2006 clearly shows the dynamic motion of the ice as well as its seasonal expansion and contraction. This animation shows the seasonal advance and retreat of sea ice over the Arctic from 8/5/2005 through 8/4/2006. The false color of the sea ice, derived from the AMSR-E 6.25 km 89 GHz brightness temperature, highlights the fissures in the sea ice by showing warmer areas of ice in a deeper blue and colder areas of sea ice in a brighter white. The sea ice extent is defined by a three-day moving average of the AMSR-E 12.5 km sea ice concentration, showing as ice all areas having a sea ice concentration greater than 15%. |

…
| Title |
Updated Jakobshavn Glacier Calving Front Retreat from 2001 through 2006 |
| Abstract |
Since measurements of Jakobshavn Isbrae were first taken in 1850, the glacier has gradually receded, finally coming to rest at a certain point for the past 5 decades. However, from 1997 to 2006, the glacier has begun to recede again, this time almost doubling in speed. The finding is important for many reasons. As more ice moves from glaciers on land into the ocean, ocean sea levels raise. 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 glacier's flow in 2000, along with changes in the glacier's calving front between 2001 and 2006. This animation is an update of and extension to animation ID #3374. In this version, a pause is added on the approach to the Jakobshavn glacier in order to highlight the meltwater lakes visible on the Greenland ice sheet. In addition, semi-transparent overlays and text indicate different regions of the glacier before the calving lines are shown. After the calving front retreat, an additional segment shows a zoom to a global view. During the pull out, historic calving front locations are shown followed by a color overlay showing regions of increase and decrease in the Greenland ice sheet. |

MODIS Sea Surface Temperatur
…
| Title |
MODIS Sea Surface Temperature from 2002 to 2006 |
| Abstract |
A recent study indicates there is a correlation between ocean nutrients and changes in sea surface temperature (SST). The results show that when ocean water warms, marine plant life in the form of microscopic phytoplankton tend to decline. When water cools, plant life flourishes.

MODIS Sea Surface Temperature from 2002 to 2006 |
| Abstract |
A recent study indicates there is a correlation between ocean nutrients and changes in sea surface temperature (SST). The results show that when ocean water warms, marine plant life in the form of microscopic phytoplankton tend to decline. When water cools, plant life flourishes. Changes in phytoplankton growth influence fishery yields and the amount of carbon dioxide the oceans remove from the atmosphere. This could have major implications on the future of our ocean's food web and how it relates to climate change. The temperature data in this visualization comes from the Moderate Resolution Imaging Spectroradiometer (MODIS) onboard NASA's Terra and Aqua spacecraft.

| Title |
Updated Jakobshavn Glacier Calving Front Retreat from 2001 through 2006 with Blue/White Elevation Change over Greenland |
| Abstract |
Since measurements of Jakobshavn Isbrae were first taken in 1850, the glacier gradually receded until about 1950, where it remained stable for the past 5 decades. However, from 1997 to 2006, the glacier has begun to recede again, this time almost doubling in speed. The finding is important for many reasons. As more ice moves from glaciers on land into the ocean, ocean sea levels raise. 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 glacier's flow in 2000, along with changes in the glacier's calving front between 2001 and 2006. This animation is an update of, and extension to, animation IDs #3374 and #3434. In this version, the pause on the approach to the Jakobshavn glacier where the meltwater lakes on the Greenland ice sheet are visible is shortened. In addition, the colors showing regions of elevation increase and decrease over the Greenland ice sheet are modified. |

MODIS Sea Surface Temperature Time Series Data Shows Increased Temperatures in Great Barrier Reef - Wide View |
| Abstract |
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. |

Antarctic Plumbing: Lake Englehardt's Subglacial Hydraulic System |
| Abstract |
ICESat satellite laser altimeter elevation profiles from 2003-2006 collected over West Antarctica reveal numerous regions of temporally varying elevation. MODIS satellite imagery over roughly the same time period collaborates where these subglacial fluctuations have occurred. These observations have led scientists to conclude that subglacial water movement is happening in this lake region, revealing a widespread, dynamic subglacial water system that could provide important insights into ice flow and the mass balance of Antarctica's ice. |

Comparing the 1998-1999 La Nina event to the corresponding 2006 Sea Surface Temperature Anomaly Conditions |
| Abstract |
Are we seeing another La Nina event in 2006? This animation compares the winter 1998-1999 La Nina event to the corresponding 2006 conditions in the Pacific Ocean. This is done by comparing Sea Surface Temperature (SST) anomalies (i.e., differences from normal SST values) between 1999 and 2006. Blue areas indicate ocean regions 5 degrees Celsius (9 degrees Fahrenheit) cooler than the norm. During the 1998-1999 La Nina event this resulted in a distinct area of deep blue stretching across the Pacific Ocean. Through this comparison, one can see that our current ocean temperature conditions do not reflect those same conditions during the 1998-1999 La Nina event. |

Floods in Malawi and Mozambi

| Title |
Floods in Malawi and Mozambique |
| Description |
Heavy rain is a part of life in Malawi and Mozambique in December and January. In these southern African countries, the two months fall in the middle of the rainy season, which runs from November to March. Though not quite as predictable as the rain, flash flooding is also common in the river valleys of southern Malawi during the rainy season. In late December 2005 and early January 2006, the rains were far more intense than normal, and true to form, the Shire River ran over its banks, displacing thousands of people, according to news reports. This pair of Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) images show what two weeks of heavy rain have done to the region. In the false-color images, both taken by MODIS on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite, water is black or dark blue. Clouds are pale blue, and plant-covered land is bright green. Bare earth is pinkish tan. In the two weeks that elapsed between December 20, 2005, lower image, and January 2, 2006, top, the land turned a deep green as plants sprang up. The Shire River, not even visible in December, expanded, soaking the land with a smudge of blue. Disruptive though the floods may be, the rains were a mixed blessing. In 2005, the rains failed during February, and crops suffered [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13273 ]. The ensuing food shortages and hunger caused the government to declare a national disaster in early December. The rich agricultural land surrounding the Shire River was among the regions most severely affected by the drought. The December and early January rains fell just as farmers were planting the primary crop of the year, but continued rainfall will still be needed to guarantee that the harvest will be better in 2006. The large images provided above are at MODIS' maximum resolution of 250 meters per pixel.

The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image on June 21, 2006, nearly one month after the lower image was taken on May 22. By June 21, the winding shape of the river is concealed by the monsoon floods. In the large image, similar flooding is visible farther north. To the left of the river, flood water drenches the ground. The region around this stretch of the river is wetland, and the image may be showing normal rainy-season conditions for the wetland. These images are shown in MODIS' shortwave and near-infrared bands to highlight the presence of water. Clear water is dark blue or black, while sediment-laden water is lighter blue. Clouds are pale blue and white, plant-covered land is green, and bare earth is tan. The large images provided above have a resolution (level of detail) of 250 meters per pixel.

| Description |
The Asian monsoon annually triggers floods along the major river systems of South Asia from the Indus River [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13769 ] in Pakistan to the Ganges and its tributaries [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13875 ] in India and the Mekong and Tonle Sap [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13796 ] in Cambodia and Vietnam. Draining Myanmar (Burma) from north to south, the Ayeyarwady (Irrawaddy) River also rose when late-season monsoon rains inundated the country in mid-September. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image of floods along the Ayeyarwady on September 25, 2006. Compared to its extent three weeks earlier (lower image), the river had spread several kilometers over its flood plain on September 25. Like many rivers, the Ayeyarwady splits into several branches across its wide, triangular delta, and it is this branching portion of the river that is shown in these images. Additional flooding is visible along the full extent of the river in the large image provided above. The images were made with both visible light (light that is visible to the human eye) and infrared light. This light combination makes it easier to distinguish water from land. Water is dark blue or black, while plant-covered land is bright green, bare land is tan, and clouds are pale blue and white. Photo-like versions of both the September 25 [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Myanmar/2006268 ] and September 5 [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Myanmar/2006248 ] images are available from the MODIS Rapid Response Team.

The Asian monsoon annually triggers floods along the major river systems of South Asia from the Indus River [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13769 ] in Pakistan to the Ganges and its tributaries [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13875 ] in India and the Mekong and Tonle Sap [ http://earthobservatory.nasa.gov/NaturalHazards/natural_hazards_v2.php3?img_id=13796 ] in Cambodia and Vietnam. Draining Myanmar (Burma) from north to south, the Ayeyarwady (Irrawaddy) River also rose when late-season monsoon rains inundated the country in mid-September. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured the top image of floods along the Ayeyarwady on September 25, 2006. Compared to its extent three weeks earlier (lower image), the river had spread several kilometers over its flood plain on September 25. Like many rivers, the Ayeyarwady splits into several branches across its wide, triangular delta, and it is this branching portion of the river that is shown in these images. Additional flooding is visible along the full extent of the river in the large image provided above. The images were made with both visible light (light that is visible to the human eye) and infrared light. This light combination makes it easier to distinguish water from land. Water is dark blue or black, while plant-covered land is bright green, bare land is tan, and clouds are pale blue and white. Photo-like versions of both the September 25 [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Myanmar/2006268 ] and September 5 [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_Myanmar/2006248 ] images are available from the MODIS Rapid Response Team.

Amazon River in the Atlantic
…
| Title |
Amazon River in the Atlantic Ocean |
| Description |
Tiny streams trickle down the east side of the glacier-clad peaks of the Andes, converging in a series of small rivers. As the rivers flow together, they wind across 6,516 kilometers (4,049 miles) of dense forest to form the world's largest river, the Amazon. Approximately 219,000 cubic meters (7,740,000 cubic feet) of water—roughly the equivalent of 88 Olympic-size swimming pools—flow from the river into the Atlantic Ocean every second. As this rapid rush of water sweeps through the Amazon Rainforest, it picks up leaves, seeds, fungi, animals, and various other bits of organic matter, as well as soil and minerals and dumps it all into the equatorial Atlantic Ocean. The huge influx of nutrients has an enormous impact on life in the Atlantic Ocean. Nutrients from the plume feed microscopic, surface-dwelling, ocean plants (phytoplankton [ http://earthobservatory.nasa.gov/Library/Phytoplankton/ ]), which in turn feed a diverse population of fish. The impact of the Amazon plume is illustrated by this pair of images, made from data collected by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite on September 30, 2006. The top image shows concentrations of chlorophyll (the energy-producing pigment that give plants their green color) in the ocean surface waters. Areas where chlorophyll concentrations are highest are yellow and correspond to the plume of water pouring from the mouth of the Amazon. Areas that are black show where chlorophyll concentrations could not be calculated because of clouds or sunglint, the glare off the ocean water that gives the upper left corner of the photo-like image (below) a washed-out appearance. Chlorophyll concentrations are likely high in the plume for two reasons. First, nutrients in the plume fertilize ocean plants, allowing them to grow more quickly near the plume. Second, the water within the plume has such a high volume and is moving so fast that it has not dispersed into the Atlantic, and plant matter from land is likely still concentrated within the plume. In fact, the Amazon plume remains concentrated enough that it can be seen meandering several kilometers across the Atlantic in the natural-color image. The plume is a band of dark water that first sweeps north on the North Brazil Current, a coastal ocean current similar to the Gulf Stream off the southeastern United States, and then snakes east in ever-fading loops on the North Equatorial Counter Current.
