4/21/09
Description Aracar volcano is one of many volcanoes in the Andes Range that is located just east of the Argentina-Chile border. Well-preserved lava flows are found at its base. Prior to a report of ash columns from the summit in 1993, the volcano was not known to be active and very little is known of the volcano's age and history. Salars, the large whitish features are very common in the arid Andes. The term salar is used exclusively of the saltwater wetlands of the Puna (high Andes) and can describe not only salt lakes but also temporary marshes, shallow lakes and lagoons, or simply salt crust. The nearby Salar del Hombre Muerto is being put into mineral production. The endeavor is expected to become one of Argentina's biggest mines, producing up to 20,000 tons of lithium carbonate and lithium chloride per year, to be extracted by pumping from the area's lithium-rich saltbeds. This image was taken from the space shuttle on Feb. 20, 2000. Image Credit: NASA/JPL/UCSD/JSC

Patagonian Ice Fields
title Patagonian Ice Fields
date 04.14.1994
description This pair of images illustrates the ability of multi-parameter radar imaging sensors such as the Spaceborne Imaging Radar-C/X-band Synthetic Aperture radar to detect climate- related changes on the Patagonian ice fields in the Andes Mountains of Chile and Argentina. The images show nearly the same area of the south Patagonian ice field as it was imaged during two space shuttle flights in 1994 that were conducted five-and-a-half months apart. The images, centered at 49.0 degrees south latitude and 73.5 degrees west longitude, include several large outlet glaciers. The images were acquired by SIR-C/X-SAR on board the space shuttle Endeavour during April and October 1994. The top image was acquired on April 14, 1994, at 10:46 p.m. local time, while the bottom image was acquired on October 5,1994, at 10:57 p.m. local time. Both were acquired during the 77th orbit of the space shuttle. The area shown is approximately 100 kilometers by 58 kilometers (62 miles by 36 miles) with north toward the upper right. The colors in the images were obtained using the following radar channels: red represents the C-band (horizontally transmitted and received), green represents the L-band (horizontally transmitted and received), blue represents the L-band (horizontally transmitted and vertically received). The overall dark tone of the colors in the central portion of the April image indicates that the interior of the ice field is covered with thick wet snow. The outlet glaciers, consisting of rough bare ice, are the brightly colored yellow and purple lobes which terminate at calving fronts into the dark waters of lakes and fiords. During the second mission the temperatures were colder and the corresponding change in snow and ice conditions is readily apparent by comparing the images. The interior of the ice field is brighter because of increased radar return from the dryer snow. The distinct green/orange boundary on the ice field indicates an abrupt change in the structure of the snowcap, a direct indication of the steep meteorological gradients known to exist in this region. The bluer color of the outlet glaciers is probably due to a thin snow cover. A portion of the terminus of the outlet glacier at the top left center of the images has advanced approximately 600 meters (1,970 feet) in the five-and-a-half months between the two missions. Because of the persistent cloud cover this observation was only possible by using the orbiting, remote imaging radar system. P-45740

Title Light and Shadow in the Carina Nebula
Full Description Previously unseen details of a mysterious, complex structure within the Carina Nebula (NGC 3372) are revealed by this image of the "Keyhole Nebula," obtained with NASA's Hubble Space Telescope. The picture is a montage assembled from four different April 1999 telescope pointings with Hubble's Wide Field Planetary Camera 2, which used six different color filters. The picture is dominated by a large, approximately circular feature, which is part of the Keyhole Nebula, named in the 19th century by Sir John Herschel. This region, about 8000 light-years from Earth, is located adjacent to the famous explosive variable star Eta Carinae, which lies just outside the field of view toward the upper right. The high resolution of the Hubble images reveals the relative three- dimensional locations of many of these features, as well as showing numerous small dark globules that may be in the process of collapsing to form new stars. Two striking large, sharp-edged dust clouds are located near the bottom center and upper left edges of the image. The former is immersed within the ring and the latter is just outside the ring. The pronounced pillars and knobs of the upper left cloud appear to point toward a luminous, massive star located just outside the field further toward the upper left, which may be responsible for illuminating and sculpting them by means of its high-energy radiation and stellar wind of high-velocity ejected material. These large dark clouds may eventually evaporate, or if there are sufficiently dense condensations within them, give birth to small star clusters. The Carina Nebula, with an overall diameter of more than 200 light- years, is one of the outstanding features of the Southern Hemisphere portion of the Milky Way. The diameter of the Keyhole ring structure shown here is about 7 light-years. These data were collected by the Hubble Heritage Team and Nolan R. Walborn (STScI), Rodolfo H. Barba' (La Plata Observatory, Argentina), and Adeline Caulet (France).

Floods in Northern Argentina
Title Floods in Northern Argentina
Description Late summer rains pounded Northern Argentina in early 2007, triggering the floods shown in this image. The rains started in mid-January, and by March 21, when the top image was taken, the rainfall had caused floods along the Parana and Dulce Rivers and around Laguna Mar Chiquita. The rains were the heaviest seen in Northern Argentina in 45 years, said the Dartmouth Flood Observatory, [ http://www.dartmouth.edu/%7efloods/Archives/2007sum.htm ] and the resulting floods killed 5 and forced 5,000 from their homes. In these images, the floods stretch out over tens of kilometers east of the Parana River. The Dulce River fans across its mouth, where it empties into the Laguna Mar Chiquita. The lower image was taken on January 18, 2007, about the time that the rains started. Like the top image, this image was made with both visible and infrared light so that water is black or dark blue and clouds are pale blue and white. Plant-covered land is green, while bare earth is tan. Agricultural areas are a brighter shade of green than natural vegetation, and the fields give the land a speckled appearance. Similar images are available from the MODIS Rapid Response System [ http://rapidfire.sci.gsfc.nasa.gov/subsets/?FAS_NArgentina/2007080 ] on a daily basis.

Floods in Northern Argentina
Title Floods in Northern Argentina
Description One of South America's longest rivers, the Parana winds south from its headwaters in central Brazil through Paraguay and Argentina to empty into the Atlantic Ocean near Buenos Aires, Argentina. Near its mouth, the river widens into a multi-stream delta where it joins the Uruguay River to form the broad Rio de la Plata estuary. Small and neatly defined at the height of summer in mid-January, the delta section of the river stretched kilometers across its flood plain in response to unusually heavy late-summer and early-autumn rains by April. The top image, taken on April 3, 2007, shows that not only has the river expanded into a broad black band, but its tributaries are also swollen. Flecks of black south and west of the river show where water covers agricultural fields. These images, both collected by the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite, were made with a combination of visible and infrared light to increase the contrast between mud-colored water and land. In these images, water is black or dark blue, and clouds are pale blue and white. Plant-covered land is bright green, and bare earth is tan. In the lower image, taken at the height of the growing season, the agricultural fields are green. By April, the crops had been harvested and the land left bare. The slightly orange color suggests that the fields may have been burned to clear away the stubble. Hugging the west bank of the Parana River, the city of Rosario is a gray-colored spot on the landscape. The floods extend north beyond the top edge of this image, affecting nearly four million hectares (15,000 square miles) and more than 70,000 people in two Argentine states, said the United Nations Office for the Coordination of Humanitarian Affairs (OCHA [ http://www.reliefweb.int/rw/rwb.nsf/db900SID/MCON-6ZX4CN?OpenDocument ]). The flooding was amplified when up to 500 millimeters of rain—more than half the average yearly rainfall—fell over northern Argentina in the span of a few days at the end of March, said OCHA.

Floods in Northern Argentina
Title Floods in Northern Argentina
Description Already swollen from late summer rain, Argentina's ParanĂ¡ River and its tributaries burst their banks under the onslaught of extreme rain during the last week of March 2007. When the clouds cleared on April 3, 2007, the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the top image of the floods in the Santa Fe and Entre Rios states, where the flood damage was worst. In the center of the image are the two state capitals, Santa Fe and ParanĂ¡. The cement-colored cities sit on opposite banks of the river, and both sustained significant damage in the floods. Dark bands of water encroach on the cities in the top image. The lower image, taken on January 13, 2007, before the unusually heavy late-summer rains began, shows the river and its tributaries under dry-season conditions. Both images were made from infrared and visible light to highlight the presence of water, which is black or dark blue in this type of image. Clouds are light blue and white, plant-covered land is green, and bare ground is tan-pink. The variegated green and tan land on either side of the river is agricultural land. In contrasting the two images, it is clear that not only have the wetlands and rivers expanded in the April 3 image, but tiny flecks of black in between the rivers indicate that farmland is flooded as well. According to the United Nations Office for the Coordination of Humanitarian Affairs (OCHA [ http://www.reliefweb.int/rw/rwb.nsf/db900SID/MCON-6ZX4CN?OpenDocument ]), the governor of Santa Fe called March's extreme rainfall "the most radical climatic phenomenon of the last 100 years." Up to 500 millimeters of rain fell over parts of Santa Fe in the span of a week, where the average annual rainfall is 900-1,000 millimeters. The rain left four million hectares (15,000 square miles) flooded, which affected more than 70,000 people, said OCHA. Several cities were flooded, including Santa Fe and ParanĂ¡, and as many as 20 were completely isolated. Damage in ParanĂ¡ was estimated to be over 10 million dollars.

Floods in Northern Argentina
Title Floods in Northern Argentina
Description Months of flooding washed even more mud into the wide Rio de la Plata estuary than usual, changing its normally tan waters to a deep chocolate brown. Floods swept across Argentina and Uruguay starting in January and ending in late March 2007, when nearly half the average annual rainfall came down in just a few days. The floods inundated farmland and isolated and damaged cities. Soy farmers may have lost more than two million metric tons of their crop in Santa Fe, the most affected province, reported Bloomberg. [ http://www.bloomberg.com/apps/news?pid=20601086&sid=ajKC2Su30zLs&refer=latin_america ] As the floods drained down the ParanĂ¡ and Uruguay Rivers, the water swept soil into the rivers. By the time the two rivers converged into the Rio de la Plata, the water was thick with sediment as shown in the top, photo-like image. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured the image on April 12, 2007. The lower image, also from Terra MODIS, was taken the previous year, when the sediment in the river was closer to normal levels. The high volume of water draining into the estuary has turned the normally calm, bland surface into multi-shaded streams of mixing water. The high flow is also pushing more sediment out into the hook-shaped SamborombĂ³n Bay on the south side of the estuary. Signs of flooding are also evident in the wetlands along the Paran&aacute River. Instead of being deep green as they were in April 2006, the wetlands are almost black under a layer of water. Tan streams of sediment flow from the main channel of the river over the soaked wetlands. Beyond the wetlands and the riverbanks are tiny tan and green squares of farmland. The silver semi-circle on the southern bank of the Rio de la Plata is Argentina's capital, Buenos Aires, and the constellation of cities that surround it. Uruguay's capital, Montevideo, is the silver area along the northern shore of the estuary in the top image (under clouds in the 2006 image).

Argentina from MODIS
Title Argentina from MODIS
Description This Moderate-resolution Imaging Spectroradiometer (MODIS) image over Argentina was acquired on April 24, 2000, and was produced using a combination of the sensor's 250-m and 500-m resolution "true color" bands. This image was presented on June 13, 2000 as a gift to Argentinian President Fernando de la Rua by NASA Administrator Dan Goldin. Note the Parana River which runs due south from the top of the image before turning east to empty into the Atlantic Ocean. Note the yellowish sediment from the Parana River mixing with the redish sediment from the Uruguay River as it empties into the Rio de la Plata. The water level of the Parana seems high, which could explain the high sediment discharge. A variety of land surface features are visible in this image. To the north, the greenish pixels show forest regions, as well as characteristic clusters of rectangular patterns of agricultural fields. In the lower left of the image, the lighter green pixels show arable regions where there is grazing and farming. (Image courtesy Jacques Descloitres, MODIS Land Group, NASA GSFC)

Title Beautiful Blooms in South Atlantic Ocean
Description Brilliant streaks of blue and duller swirls of green color the South Atlantic Ocean in this Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) image, taken on January 4, 2005, by NASA's Terra [ http://terra.nasa.gov/ ] satellite. The colors are a result of millions of microscopic plants growing near the surface of the water. Called phytoplankton, some varieties of the plants are coated with white scales. When viewed through the ocean waters, the floating white plants appear blue. In places, chlorophyll gives the waters a green tint. Phytoplankton blooms are common where cold ocean currents carry nutrients from the bottom of the ocean to the surface. In this case, the bloom has developed in the Falkland or Malvinas Current, which sweeps north from Antarctica. Additional nutrients are fed into this part of the ocean by the Rio de la Plata, which empties into the Atlantic immediately west of the region shown in this image. The influx of nutrients allows large blooms to develop frequently in this section of the southern Atlantic, off the coast of Argentina and Uruguay. As a primary food source for many fish, the blooms support a strong marine ecosystem.

Floods in Uruguay
Title Floods in Uruguay
Description Above average rains over the past two months have given rise to floods throughout Uruguay. The false-color image of the flood (right) was acquired on April 27, 2002, by the Moderate-resolution Imaging Spectroradiometer (MODIS), flying aboard NASA?s Terra spacecraft. Over 3600 hundred people have been evacuated from their homes in Uruguay, and many highways have been shut down. The large river running down the border between Uruguay and Argentina is the Uruguay River, and the spidery lake in the center of Uruguay is Lake Rincon del Bonete. Normally, the lake and its tributaries cover a much smaller area (left image, acquired on April 2, 2002). In these false-color images, land surfaces are tan and beige and water is black. The pinkish-white patches are clouds. To obtain a high-resolution copies of the scene acquired on April 2 (shown above, left), visit the MODIS Rapid Response Image Gallery [ http://rapidfire.sci.gsfc.nasa.gov/gallery/?2002117-0427 ].

Title Cold and Snow in South America
Description As winter settles over the Southern Hemisphere, South America has been lashed with snow, heavy rain and intense cold since the final week of June 2004. In southern Peru, heavy snow has collapsed hundreds of homes and buildings, and killed over 75,000 farm animals. The country is struggling to provide emergency provisions to people in the poverty-stricken region, many of whom are being treated for cold-related illnesses such as pneumonia. In many mountain regions, the temperature has plummeted to -20 Celsius (-4 Fahrenheit). The cold weather also caused deaths in Argentina and Chile. Unusually cold temperatures, down to -7 Celsius (19.4 Fahrenheit), chilled southern Brazil. This Moderate Resolution Imaging Spectroradiometer [ http://modis.gsfc.nasa.gov ] (MODIS) image shows the snow in the mountains of southern Peru and northern Chile and Bolivia. Unlike the clouds that litter the scene, the snow clings to the contours of the mountain peaks. The image was acquired on July 13, 2004, by MODIS on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite.

Title Dark Water near Rio de la Plata
Description On April 28, 2002, the Sea-viewing Wide Field-of-view Sensor (SeaWiFS) captured this image of very bright, sediment-laden water in the Rio de la Plata of South America. Along the coast to the northwest, however, very little light was reflected back to the orbiting sensor. It is not clear what is causing this large, very dark patch of water. Perhaps a phytoplankton bloom being fed by high-nutrient runoff was responsible for absorbing much of the solar radiation that was not absorbed by the water itself. The metropolitan area of Buenos Aires, Argentina, is readily visible as a large gray splotch just below the western end of the Rio de la Plata estuary. Other smaller splotches mark cities such as La Plata (just southeast of Buenos Aires) and Montevideo (on the northern side of the estuary).

Title Dust Storm near Laguna Mar Chiquita
Description Two tendrils of dust blew northward from Laguna Mar Chiquita in Argentina on July 27, 2006. The Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov/ ] flying onboard NASA's Aqua [ http://aqua.nasa.gov/ ] satellite took this picture the same day. The dust plumes appear as white wisps that fan out as they blow northward. The small red outlines are hotspots, where the satellite sensor detected areas with unusually high surface temperatures, probably fires. Mar Chiquita is a permanent saltwater lagoon in the Argentine provinces of Cordoba and Santiago del Estero. The lagoon is roughly 100 by 40 kilometers and 4 meters deep. Each year, the lagoon's water level, surface area, and salinity change. Beginning in 1977, the lagoon level increased and salt concentration decreased. This was likely due to a series of unusually wet years. Whenever the lake level recedes, however, the dry lakebed sediments provide material for dust storms. Characteristic of lakebed sediments, the dust plumes shown in this image are very light in color.

EO-1 Launches!
Title EO-1 Launches!
Description These photos [view expanded images of launch (left) or view from above (right)] show the launch of the Boeing Delta II rocket from Vandenberg Air Force Base, CA, at 10:24 a.m. on November 21 PST, carrying a payload of three satellites into orbit. The payload included NASA's Earth Observer-1 (EO-1), Argentina's SAC-C, and Sweden's Munin spacecraft. Sixty minutes after lift-off, EO-1 was successfully deployed in orbit, SAC-C was deployed about 30 minutes later, and Munin deployed shortly after that. All three satellites are performing well. The launch of EO-1 marks the beginning of NASA's New Millennium Program (NMP), in which NASA is developing smaller, lighter spacecraft that meet or exceed the performance of current satellite technologies. The goal of NMP is to improve the on-orbit measurement capabilities of satellites while reducing the cost to build and launch them into space. Because its purpose is to demonstrate new technology on orbit, data from EO-1 will be made available only after the team completes its calibration and validation activities. Over the next two weeks, EO-1 and SAC-C will gradually be moved into their final orbital trajectories--flying very nearly from pole to pole at an altitude of 705 kilometers. The objective is to fly them in formation with Landsat 7 and Terra, two of NASA's Earth Observing System (EOS) satellites already in orbit, so that their data may be cross compared for calibration and validation purposes. EO-1 will follow about 60 seconds behind Landsat 7, descending southward across the equator at about 10:16 a.m. local time. For more information see: * ?

Maipo Volcano, Chile
Title Maipo Volcano, Chile
Description The high peaks of the Andes form the backbone of South America and the political border between Chile and Argentina. Formed from the subduction of the Nazca Plate under the South American Plate, the south-central Andes also includes several major volcanoes. One of the most active border volcanoes is Volcan Maipo, located just southeast of Santiago, Chile. The volcano's summit (5264m) rests in the large Diamante Caldera, and is defined by a radial drainage pattern highlighted by snow cover (center right of image). Lava flows from an 1826 eruption blocked drainage within the caldera, forming Lake Diamante. The lake is a popular tourist destination. Maipo's last significant eruption was in 1908. Imagery of the region from the International Space Station includes seasonal observations—this image shows the volcano near the southern hemisphere spring equinox. The lake, just east of Maipo's peak, is still ice covered. However, the increasing temperatures of spring are suggested by a muddy-looking streak near the lower left corner. The streak appears to be a landslide or avalanche that flowed westward down a rugged slope, possibly triggered by instability in the snowpack due to snow melt. Astronaut photograph ISS009-E-22625 [ http://eol.jsc.nasa.gov/scripts/sseop/photo.pl?mission=ISS009&roll=E&frame=22625 ] was acquired September 14, 2004 with a Kodak 760C digital camera with a 180 mm lens, and is provided by the ISS Crew Earth Observations experiment and the Image Science & Analysis Group, Johnson Space Center. The International Space Station Program [ http://spaceflight.nasa.gov/ ] supports the laboratory to help astronauts take pictures of Earth that will be of the greatest value to scientists and the public, and to make those images freely available on the Internet. Additional images taken by astronauts and cosmonauts can be viewed at the NASA/JSC Gateway to Astronaut Photography of Earth. [ http://eol.jsc.nasa.gov/ ]
Fires and Thick Smoke over S …
Title Fires and Thick Smoke over South America
Description The skies over the heart of South America were thick with the smoke from thousands of fires on September 9, 2007. In this image from the Moderate Resolution Imaging Spectroradiometer (MODIS) [ http://modis.gsfc.nasa.gov ] on NASA's Aqua [ http://aqua.nasa.gov ], challenging for scientists to say what the overall effect of smoke on clouds and rainfall is. NASA's Terra [ http://terra.nasa.gov ] and Aqua [ http://aqua.nasa.gov ] satellites each have a MODIS sensor capable of detecting fires and mapping the extent of smoke aerosols on a daily basis. Scientists from around the world are using these data to advance our understanding of how natural and human-caused fires are changing our planet. NASA image created by Jesse Allen, using data provided courtesy of the MODIS Rapid Response [ http://rapidfire.sci.gsfc.nasa.gov/ ] team., satellite, locations where the sensor detected actively burning fires are marked with red dots. The skies are flooded with smoke, which pools along the eastern foothills of the Andes Mountains for thousands of kilometers. (North-to-south this image covers 3,050 kilometers, if we laid it over a map of the central United States, it would spill over the borders into both Canada and the Gulf of Mexico for at least a hundred kilometers in both directions.) Although naturally occurring fires are not uncommon in the drier forests and grasslands of South America, this type of intense, continent-spanning fire activity is almost certainly a product of human activities. Some fires are intentional, set by people to clear forest, savannas, and grasslands for ranching or farming. Other fires occur accidentally from human activities. Landscapes that have been disturbed by logging, fragmentation, or previous accidental fire are more prone to catch fire accidentally. In these situations, planned fires (such as brush clearing fires on already cleared land) can easily get out of control and invade other areas, especially during drought years. The image spans a variety of ecological regions. The top of the scene, including Peru, northern Bolivia, and western Brazil is home to the southernmost portions of the Amazon Rainforest. These wetter forests give way to the south to drier forests and more open woodlands in southern Bolivia, northwestern Paraguay and northern Argentina east of the Andes, this area is called the Chaco. In Uruguay and southern Brazil, the natural vegetation is savannas and grasslands. Even in ecosystems where fires occur naturally (the Chaco, savannas, and grasslands), human activities may change the frequency and intensity of fires. The number and different kinds of plants and animals may change as a result. And in the Amazon, naturally occurring fire was historically very rare, and trees and other plants have no real adaptations to fire. Fires in the rainforest have the potential to completely transform the Southern Amazon forests into a savanna. Fires influence not only the land surface, but the atmosphere as well. Research suggests that the impacts of smoke on the tropical atmosphere vary from place to place, season to season, and year to year. Studies have shown smoke reducing cloudiness over the Amazon itself, but not over the nearby ocean and not every year. The net impact on rainfall is also uncertain. Smoke particles suppress cloud formation by providing an over-abundance of condensation sites for water vapor. The water vapor spreads out over these particles, and it takes the cloud droplets longer to get big enough to fall as rain. The flip side, however, is that the smaller, lighter cloud droplets can rise much higher into the atmosphere, which ultimately invigorates updrafts, intensifies thunderstorms, and produces large hail and heavy rain. The competing effects in different areas and weather conditions make it extremely

Description Hundreds of fires were detected across South America by the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite on August 1, 2003. Fires (red dots) were detected in Brazil (right), Argentina (bottom left), and Paraguay (top left). Biomass burning is concentrated during the months of July-October in the Southern Hemisphere portion of South America, and is linked to agricultural activities, including the use of fire to permanently deforest areas and convert them to agricultural land. In the image, isolated patches of intact forest appear deep green, while agricultural lands and tropical savannas appear lighter green.

Title Fires in Brazil, Argentina, and Paraguay
Description Scores of fires (red dots) burn across the South American countries of (clockwise from upper right) Bolivia, Paraguay, Brazil, Uruguay, and Argentina in this true-color Moderate Resolution Imaging Spectroradiometer (MODIS) image from the Aqua satellite acquired on August 11, 2003. The fires, which are marked in red, are mostly concentrated in the Gran Chaco region, which stretches across northeastern Argentina, southern Bolivia, and southern Paraguay. The Gran Chaco is an extensive arid lowland plain that is alternately dotted with swamps (in the rainy season) and dense forests. The region is sparsely populated, some of the highest temperatures in South America have been recorded here, and there are only a few crops for settlers to grow that will survive in the region. Cotton is one: it is grown primarily in the Chaco Central, south of the Pilcomayo River in Argentina. The forests are home to the quebracho tree (source of much of the vegetable tanin used in leather curing) which is one of the most durable hardwood trees, and is the other pillar of the Gran Chaco's economy. Unfortunately, due to its popularity, quebracho tree populations are dwindling. Image courtesy Jeff Schmaltz, MODIS Rapid Response Team, NASA GSFC

Patagonian Glacier
Title Patagonian Glacier
Description This image of a Patagonian glacier was aqcuired by the Advanced Spaceborne Thermal Emission and Reflection Radiometer (ASTER) on May 2, 2000. Patagonia is a mountainous region spanning the border between Chile and Argentina near the southern tip of South America. The image covers an area of 36 x 30 km?the full-size image has a resolution of 15 meters per pixel. Vegetation appears red in the image, which is a false-color composite of near-infrared, red, and green light displayed as red, green, and blue, respectively. This large glacier is riddled with crevasses?deep cracks in the ice. The semi-circular ridge at the far left of the image is composed of rock and soil carried there by the glacier which was even larger in the past. This type of feature is called a ?terminal moraine?. The pools of water at the foot of the glacier are light-colored due to the fine silt suspended in them. A braided stream winds through more silt deposited by the glacier and cuts through the terminal moraine about one third of the way down from its top. Along the right side of the image are a series of parallel valleys that were likely cut by arms of the glacier which have since receded.

Phytoplankton Bloom off Arge …
Title Phytoplankton Bloom off Argentina
Description Many factors combine to make the Atlantic Ocean off the coast of Argentina a highly productive ecosystem. In this region, cool, nutrient-rich water from the Antarctic mixes with warm, salty water flowing south from Brazil. The water is turbid where the two currents meet, and the churning waters bring additional nutrients to the surface. Yet another source of nutrients is the Rio de la Plata, the wide estuary through which the ParanĂ¡ and Uruguay Rivers empty into the ocean. Brown clouds of iron-rich sediment from the Rio de la Plata are visible along the top edge of the image. The infusion of fresh water from the rivers also carries agricultural run-off and other nutrients into the ocean. Between the upwelling created by the converging currents and the flow of nutrients from the Rio de la Plata, the waters of the South Atlantic are a paradise for marine life ranging from fish to microscopic surface plants. The brilliant swirls of green and blue shown in this image attest to the productivity of the South Atlantic Ocean off Argentina. The colors have been created by millions of tiny plants, phytoplankton, growing in the surface waters. Chlorophyll and other pigments in the plants can give the water dark blue or green colors. Bright blue areas are often the result of the white, calcium carbonate (chalk) scales of organisms called coccolithophores reflecting light through the top layer of the ocean. Phytoplankton are the base of the marine food chain. The Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Aqua [ http://aqua.nasa.gov/ ] satellite captured this image on March 5, 2006. The large image provided above is at MODIS' maximum resolution of 250 meters per pixel. The image is available in additional resolutions from the MODIS Rapid Response Team.

Title Phytoplankton Bloom off Argentina
Description The Atlantic Ocean was awash with color on December 18, 2006, when the Moderate Resolution Imaging Spectroradiometer (MODIS [ http://modis.gsfc.nasa.gov ]) on NASA's Terra [ http://terra.nasa.gov/ ] satellite captured this image. The brilliant greens and blues are densely concentrated, microscopic plants growing on the surface of the ocean. Called phytoplankton, the plants thrive in the cool, nutrient-rich waters off the coast of Argentina. Here, the Malvinas (Falkland) Current sweeps north from the frigid Southern Ocean along the shallow continental shelf. The interaction of the current with the edge of the shelf pulls nutrients from the shelf floor to the surface, and this provides the "fertilizer" needed to drive plant growth. The resulting bloom stretches in a long, thin line along the continental shelf. Because phytoplankton sit at the base of the marine food chain, the parts of the ocean that support large blooms tend to have a large and diverse population of fish and other animals. Phytoplankton also play an important role in the global carbon cycle. Like all plants, phytoplankton soak up carbon dioxide, providing a crucial sink for the greenhouse gas. Rising ocean temperatures in the past decade have caused global phytoplankton productivity to decline [ http://earthobservatory.nasa.gov/Newsroom/NewImages/images.php3?img_id=17482 ], though some evidence suggests that productivity in the South Atlantic off Argentina may be increasing.

Title Fires in Central South America
Description On March 24, 2004, the Moderate Resolution Imaging Spectroradiometer (MODIS) on the Aqua satellite captured this image of central South America, showing fires burning in Argentina (left), Paraguay (top center), and Brazil (right). Fires have been marked with red dots. The dark green peninsular arm of Argentina is the Misiones province, which contains a mostly intact remnant of the extremely endangered Atlantic Rainforest ecosystem. The widespread nature of the fires and their location (generally located in areas of low vegetation (tan and light green) suggests that these fires are being set intentionally for agricultural purposes. Though not necessarily immediately hazardous, such large-scale burning can have a strong impact on weather, climate, human health, and natural resources. The high-resolution image provided above is 500 meters per pixel. The MODIS Rapid Response System provides this image at additional resolutions.
