Landsat View: Pearl River Delta, China

In 1979, China established two special economic zones around the Pearl River Delta, north of Hong Kong. This image, taken by Landsat 3 on October 19, 1973, shows that the region was rural when the zone was established. Plant-covered land, which is red in this false-color image, dominates the scene. Square grids are agriculture. By January 10, 2003, when Landsat 7 took this image, the Pearl River Delta was a densely populated urban corridor with several large cities. The urban areas are gray in this image. The region is a major manufacturing center with an economy the size of Taiwan’s. As of 2010, the Pearl River Economic Zone had a population of 36 million people. ---- NASA and the U.S. Department of the Interior through the U.S. Geological Survey (USGS) jointly manage Landsat, and the USGS preserves a 40-year archive of Landsat images that is freely available over the Internet. The next Landsat satellite, now known as the Landsat Data Continuity Mission (LDCM) and later to be called Landsat 8, is scheduled for launch in 2013.

Nazca Lines, Peru

Acquisition Date: November 10, 2002 In the desert of southwest Peru, between the Andes Mountains and the Peruvian coast, lies a plateau with huge geometric patterns and spirals, animal figures including a monkey, a spider, and an 'owl man,' and thousands of perfectly straight lines. The last of these was drawn about a thousand years ago. Known as the Nazca lines, the drawings have mystified scientists since they were first discovered in the 1920s. Pictured here is all that can be seen of these lines by Landsat 7's 15 meter pan band, which has been used to sharpen the 30 meter Bands 3, 2, and 1.

Akpatok Island

January 1st, 2001: Description: Akpatok Island lies in Ungava Bay in northern Quebec, Canada. Accessible only by air, Akpatok Island rises out of the water as sheer cliffs that soar 500 to 800 feet (150 to 243m) above the sea surface. The island is an important sanctuary for cliff-nesting seabirds. Numerous ice floes around the island attract walrus and whales, making Akpatok a traditional hunting ground for native Inuit people.

Icefall, Lambert Glacier, Antarctica

Image taken 12/2/2000: The Lambert Glacier in Antarctica, is the world's largest glacier. The focal point of this image is an icefall that feeds into the Lambert glacier from the vast ice sheet covering the polar plateau. Ice flows like water, albeit much more slowly. Cracks can be seen in this icefall as it bends and twists on its slow-motion descent 1300 feet (400 meters) to the glacier below. This Icefall can be found on Landsat 7 WRS Path 42 Row 133/134/135, center: -70.92, 69.15.

Landsat View: Tehran, Iran

Between 1985 and 2009, the population of Tehran, Iran, grew from six million to just over seven million. The city's growth was spurred largely by migration from other parts of the country. In addition to being the hub of government and associated public sector jobs, Tehran houses more than half of Iran's industry. Landsat 5 acquired these false-color images of Tehran on August 2, 1985, and July 19, 2009. The city is a web of dark purple lines, vegetation is green and bare ground is pink and tan. The images were created using both infrared and visible light (band combination 7, 4, and 2) to distinguish urban areas from the surrounding desert. ---- NASA and the U.S. Department of the Interior through the U.S. Geological Survey (USGS) jointly manage Landsat, and the USGS preserves a 40-year archive of Landsat images that is freely available over the Internet.

Ocean Sand, Bahamas

NASA image acquired January 17, 2001 Though the above image may resemble a new age painting straight out of an art gallery in Venice Beach, California, it is in fact a satellite image of the sands and seaweed in the Bahamas. The image was taken by the Enhanced Thematic Mapper plus (ETM+) instrument aboard the Landsat 7 satellite. Tides and ocean currents in the Bahamas sculpted the sand and seaweed beds into these multicolored, fluted patterns in much the same way that winds sculpted the vast sand dunes in the Sahara Desert.

Landsat View: Tokyo, Japan

Tokyo is the world’s largest metropolitan region, home to nearly 37 million people. During the past two decades, Tokyo’s population has grown by more than 7 million. The city’s growth has continued despite Japan’s overall stagnating population, mainly due to a continued trend of centralization—citizens moving out of the country and into the city. Landsat 4 collected this first false-color image of Tokyo on Feb. 2, 1989. The upper half of Tokyo Bay is the large water body visible in a dark blue. In the middle of the image, central Tokyo appears a deep purple just north of the bay. Twenty-two years later, Landsat 5, captured this second image of Tokyo on April 5, 2011. The urban reaches of metropolitan Tokyo have grown in both distance and density, as seen where the green color of vegetation has turned to pink and purple shades of urbanization. A major expansion of Tokyo’s Haneda Airport, can be seen south of the city, on land built out into the bay. The constant circular spot of green in the dense city-center, visible on both images, is the Tokyo Imperial Palace and its gardens.

Landsat View: Ouagadougou, Burkina Faso

The landlocked western African nation of Burkina Faso experienced a 200 percent increase in urban population between 1975 and 2000. As a result, the area of the capital city Ouagadougou grew 14-fold during this period. These Landsat images show the city expanding outward from its center in the two decades between 1986 and 2006. On Nov. 18, 1986, the Landsat 5 satellite acquired this image of the capital. This false-color image shows vegetation in shades of green and gray, water in various shades of blue, and urban areas in pink and purple. The runway of the city’s airport can be seen as a long straight line that extends from southwest to northeast south of the large lake, Bois de Boulogne. Two decades later, on Oct. 16, 2006 Landsat 7 acquired this image of Ouagadougou. Growth radiated from the city center in all directions. The green strip of vegetation north of Bois de Boulogne has been paved over and a massive new development including a large thoroughfare and traffic circle can be seen south of the airport. ---- NASA and the U.S. Department of the Interior through the U.S. Geological Survey (USGS) jointly manage Landsat, and the USGS preserves a 40-year archive of Landsat images that is freely available over the Internet.

$NASA image acquired September 15, 1999 This Landsat 7 image of clouds off the Chilean coast near the Juan Fernandez Islands (also known as the Robinson Crusoe Islands) on September 15, 1999, shows a unique pattern called a “von Karman vortex street.” This pattern has long been studied in the laboratory, where the vortices are created by oil flowing past a cylindrical obstacle, making a string of vortices only several tens of centimeters long. Study of this classic “flow past a circular cylinder” has been very important in the understanding of laminar and turbulent fluid flow that controls a wide variety of phenomena, from the lift under an aircraft wing to Earth’s weather. Here, the cylinder is replaced by Alejandro Selkirk Island (named after the true “Robinson Crusoe,” who was stranded here for many months in the early 1700s). The island is about 1.5 km in diameter, and rises 1.6 km into a layer of marine stratocumulus clouds. This type of cloud is important for its strong cooling of the Earth’s surface, partially counteracting the Greenhouse warming. An extended, steady equatorward wind creates vortices with clockwise flow off the eastern edge and counterclockwise flow off the western edge of the island. The vortices grow as they advect hundreds of kilometers downwind, making a street 10,000 times longer than those made in the laboratory. Observing the same phenomenon extended over such a wide range of sizes dramatizes the “fractal” nature of atmospheric convection and clouds. Fractals are characteristic of fluid flow and other dynamic systems that exhibit “chaotic” motions. Both clockwise and counter-clockwise vortices are generated by flow around the island. As the flow separates from the island’s leeward (away from the source of the wind) side, the vortices “swallow” some of the clear air over the island. (Much of the island air is cloudless due to a local “land breeze” circulation set up by the larger heat capacity of the waters surrounding the island.) The “swallowed” gulps of clear island air get carried along within the vortices, but these are soon mixed into the surrounding clouds. Landsat is unique in its ability to image both the small-scale eddies that mix clear and cloudy air, down to the 30 meter pixel size of Landsat, but also having a wide enough field-of-view, 180 km, to reveal the connection of the turbulence to large-scale flows such as the subtropical oceanic gyres. Landsat 7, with its new onboard digital recorder, has extended this capability away from the few Landsat ground stations to remote areas such as Alejandro Island, and thus is gradually providing a global dynamic picture of evolving human-scale phenomena.

North Korea Drought

North Korea's state news agency reported the country is facing its worst drought in a century. Rice-growing provinces have been badly affected and more than 30% of rice paddies were parching up. A Landsat 7 image from June 29, 2002, compared with an ASTER image from June 26, 2015, shows the disparity in the rice crop. The images display vegetation in red, and bare fields in dark blue. The images cover an area of 27 x 34.5 km, and are located at 38.5 degrees north, 125.6 degrees east. http://photojournal.jpl.nasa.gov/catalog/PIA19501

Earth Observations taken by the Expedition 13 crew

ISS013-E-13549 (2 May 2006) --- Washington, DC is featured in this image photographed by an Expedition 13 crewmember on the International Space Station. When the image was exposed, the orbital outpost was located over the western border of Maryland and West Virginia. The resolution and extent of the true-color, handheld image is similar to the 15-meter/pixel data obtained by sensors onboard the unmanned Landsat-7 and Terra satellites. This resolution is sufficient to capture the sunglint off the Capitol Building's dome. Other major landmarks that are visible include the Washington Monument, the Pentagon (bottom left, southwest of the Potomac River), and the Lincoln Memorial, along the northwest bank of the Potomac.

Lake Mead and Drought

Lake Mead supplies water for Arizona, California, Mexico, and other western states. On June 23, the water level fell to 1075 feet, a record low. In 2000, for comparison, the water level was at 1214 feet. A 15-year drought and increased demands for water are to blame for the critical status of the water supply. The difference in 15 years is seen in this pair of images of the western part of Lake Mead, acquired June 21, 2000 by Landsat 7, and June 21, 2015 by ASTER. The images cover an area of 22.5 x 28.5 km, and are located at 36.1 degrees north, 114.7 degrees west. http://photojournal.jpl.nasa.gov/catalog/PIA19731

New Orleans, Louisiana

On Sunday, February 3, roughly 800 million eyes from all over the world focused on the Louisiana Superdome in New Orleans as the New England Patriots battled the St. Louis Rams for the NFL Championship in Super Bowl XXXVI. This true color image of New Orleans was acquired on April 26, 2000, by the Enhanced Thematic Mapper plus (ETM+), flying aboard the Landsat 7 satellite. Lake Pontchartrain borders the city to the north. The big river winding its way east to west through the image is the Mississippi. The Louisiana Superdome, built in 1975, sits just inside the rightmost portion of the big river bend that cradles downtown New Orleans. The city, however, may not be around to hold a Super Bowl in 2102. New Orleans is slowly sinking into the Gulf of Mexico. The construction of flood walls and dams north of New Orleans over the past century have prevented sediments carried by the Mississippi River from reaching New Orleans and the Mississippi River Delta. Before the dams were built, river sediments would empty out onto the delta adding layer upon layer of new soil each year. The additional soil prevented the Gulf from subsuming the delta. Unless drastic measures are taken, the city and the delta could be awash in seawater by the end of this century.

Lagoons and Reefs of New Caledonia

NASA image acquired May 10, 2001 In July 2008, the United Nations Educational, Scientific, and Cultural Organization (UNESCO) added 27 new areas to its list of World Heritage sites. One of those areas included the lagoons of New Caledonia. Some 1,200 kilometers (750 miles) east of Australia, this French-governed archipelago contains the world’s third-largest coral reef structure. The coral reefs enclose the waters near the islands in shallow lagoons of impressive biodiversity. On May 10, 2001, the Enhanced Thematic Mapper Plus on NASA’s Landsat 7 satellite captured this image of Île Balabio, off the northern tip of Grande Terra, New Caledonia’s main island. In this natural-color image, the islands appear in shades of green and brown—mixtures of vegetation and bare ground. The surrounding waters range in color from pale aquamarine to deep blue, and the color differences result from varying depths. Over coral reef ridges and sand bars, the water is shallowest and palest in color. Darker shades of blue characterize deeper waters. Reef-enclosed, shallow waters surround Île Balabio, and a larger, semi-enclosed lagoon appears immediately east of that island. Immediately north of Grande Terra, unenclosed, deeper waters predominate. The coral reefs around New Caledonia support an unusual diversity of species, including large numbers of predators and big fish, turtles, and the world’s third-largest dugong population.

Budapest, Hungary, Perspective View, SRTM Elevation Model with Landsat Overlay

After draining the northern flank of the Alps Mountains in Germany and Austria, the Danube River flows east as it enters this west-looking scene (upper right) and forms the border between Slovakia and Hungary. The river then leaves the border as it enters Hungary and transects the Transdanubian Mountains, which trend southwest to northeast. Upon exiting the mountains, the river turns southward, flowing past Budapest (purplish blue area) and along the western margin of the Great Hungarian Plain. South and west of the Danube, the Transdanubian Mountains have at most only about 400 meters (about 1300 feet) of relief but they exhibit varied landforms, which include volcanic, tectonic, fluvial (river), and eolian (wind) features. A thick deposit of loess (dust deposits likely blown from ancient glacial outwash) covers much of this area, and winds from the northwest, funneled between the Alps and the Carpathian Mountains, are apparently responsible for a radial pattern of erosional streaks across the entire region. This image was generated from a Landsat satellite image draped over an elevation model produced by the Shuttle Radar Topography Mission (SRTM). The view uses a 3-times vertical exaggeration to enhance topographic expression. The false colors of the scene result from displaying Landsat bands 1, 4, and 7 in blue, green, and red, respectively. Band 1 is visible blue light, but bands 4 and 7 are reflected infrared light. This band combination maximizes color contrasts between the major land cover types, namely vegetation (green), bare ground (red), and water (blue). Shading of the elevation model was used to further highlight the topographic features. http://photojournal.jpl.nasa.gov/catalog/PIA04952

Payún Volcanic Field

Situated in the southern Andes Mountains, the Payún volcanic field of Argentina is a complex landscape that formed over hundreds of thousands of years. Sprawling over 5,200 square kilometers (2,000 square miles), Payún is a massive shield volcano—a broad formation resembling an ancient warrior shield. This false-color image is a composite of observations acquired on February 7 and March 20, 2001 by the Enhanced Thematic Mapper Plus on the Landsat 7 satellite. It was made from a combination of visible and infrared light, where green indicates vegetation, black indicates lava flows, and orange is bare rock rich in iron oxides. Part of the back-arc volcanism of the Andes, Payún lies about 530 kilometers (330 miles) east from where the Nazca plate subducts below the South America plate. Not surprisingly, a volcanic zone extends over some 1,000 kilometers (600 miles) north-to-south in this region. According to a study published in 2010, the regional geology and chemical composition of the rocks indicate that the volcanic field likely formed within the past 300,000 years. The dominant feature of the volcanic field is Payún Matru, an elliptical caldera measuring roughly 9 by 7 kilometers (6 by 4 miles). Geologists surmise that the caldera formed after the old magma chamber emptied and the summit collapsed. Southwest of the caldera is a stratovolcano composed of alternating layers of compacted ash, hardened lava, and rocks ejected during previous eruptions. This stratovolcano, Payún, rises to 3,680 meters (12,073 feet) above sea level. (The entire volcanic field sits at 2,000 meters, or 6,600 feet.) The stratovolcano may be the most prominent feature in the volcanic field but it is by no means the only one. More than 300 eruptive features litter the shield volcano, most of them occupying an east-west line. West of Payún Matru is an area known as Los Volcanes, a mass of strombolian cones and basaltic lava flows. Image courtesy Michael P.

Retreat of Greenland's Zachariae Isstrom Glacier

Satellite images from 2022 (Main image) and 1999 (Figure A) capture the retreat of Zachariae Isstrom, a glacier in northeast Greenland, as icebergs broke off its edge over the course of 23 years. In a recent study in Nature, researchers from NASA's Jet Propulsion Laboratory in Southern California calculated that Zachariae lost an estimated 176 billion tons (160 billion metric tons) of ice in the period between 1985 and 2022. That was the greatest mass lost for the period of any of the 207 glaciers analyzed in the paper. The earlier image was taken by the Enhanced Thematic Mapper Plus on the Landsat 7 satellite on Aug. 5, 1999, while the later image was captured by the Operational Land Imager on the Landsat 8 satellite on Aug. 22, 2022. The study took a comprehensive look at glacial retreat around the edges of the entire Greenland Ice Sheet from 1985 to 2022 and found that 179 glaciers retreated significantly since 1985, 27 held steady, and just one advanced slightly. The study found that overall the ice sheet shed about 1,140 billion tons (1,034 billion metric tons) of ice from 1985 to 2022, one-fifth more mass than previously estimated, as icebergs fell into the ocean at an accelerating rate. Most of the ice loss came from below sea level, in fjords on Greenland's periphery. Once occupied by ancient glacial ice, many of these deep coastal valleys have filled with seawater – meaning the ice that broke off made little net contribution to sea level. But the loss likely accelerated the movement of ice flowing down from higher elevations, which in turn added to sea level rise. It also added previously unaccounted-for fresh water to the North Atlantic Ocean, which could have impacts on global ocean currents. https://photojournal.jpl.nasa.gov/catalog/PIA26118

Snow In the Sahara

In December 2016, snow fell in the Sahara for the first time since 1979. In 1984, the charitable supergroup Band Aid sang: “There won’t be snow in Africa this Christmas time.” In fact, it does snow in Africa at high elevations. Kilimanjaro has long had a cap of snow and ice, though it has been shrinking. Skiiers travel for natural and manufactured snow in the Atlas Mountains of Morocco and Algeria, as well as a few spots in South Africa and Lesotho. Nonetheless, snow on the edge of the Sahara Desert is rare. On December 19, 2016, snow fell on the Algerian town of Ain Sefra, which is sometimes referred to as the “gateway to the desert.” The town of roughly 35,000 people sits between the Atlas Mountains and the northern edge of the Sahara. The last recorded snowfall in Ain Sefra occurred in February 1979. The Enhanced Thematic Mapper Plus (ETM+) on the Landsat 7 satellite acquired this natural-color image of snow in North Africa on December 19, 2016. This scene shows an area near the border of Morocco and Algeria, south of the city of Bouarfa and southwest of Ain Sefra. Though the news has been dominated by snow in the Saharan city, a review of several years of satellite data suggests that snow is also pretty rare in this section of the Atlas range.

Big Bend National Park

Alternately known as a geologist’s paradise and a geologist’s nightmare, Big Bend National Park in southwestern Texas offers a multitude of rock formations. Sparse vegetation makes finding and observing the rocks easy, but they document a complicated geologic history extending back 500 million years. On May 10, 2002, the Enhanced Thematic Mapper Plus on NASA’s Landsat 7 satellite captured this natural-color image of Big Bend National Park. A black line delineates the park perimeter. The arid landscape appears in muted earth tones, some of the darkest hues associated with volcanic structures, especially the Rosillos and Chisos Mountains. Despite its bone-dry appearance, Big Bend National Park is home to some 1,200 plant species, and hosts more kinds of cacti, birds, and bats than any other U.S. national park.

Redwood National Park

In 1968, after state parks had already been established in northern California, the U.S. Congress established Redwood National Park. This new park supplemented protected lands in the region, and in 1994, state and federal authorities agreed to jointly manage the area’s public lands. On February 6, 2003, the Enhanced Thamatic Mapper Plus on NASA’s Landsat 7 satellite captured this true-color image of the southern end of Redwood National Park - a thin coastal corridor connects the northern and southern ends of the park system. Along the coast, sandy beaches appear off-white, and sediments form swirls of pale blue in the darker blue sea. Inland, the park is dominated by green vegetation, with isolated patches of gray-beige rock. This image of the Redwood National Park includes two stands of trees: Lady Bird Johnson Grove and Tall Trees Grove. The first grove was dedicated to the former first lady by President Richard Nixon in August 1969. The second grove became the focus of efforts to protect the surrounding area from logging. Two waterways appear in this image: Redwood Creek and Klamath River. The more conspicuous Klamath River flows through the park system’s midsection (north of the area pictured here). Redwood Creek flows through the southern portion of the park system. Both waterways have carved gorges through the mountainous landscape. Redwood National and State Parks occupy an area considered to be the most seismically active in the United States. The frequent seismic activity has led to shifting waterways, landslides, and rapid erosion along the coastline.

ISS01-E-5113 (December 2000) --- This scene on the remote, rugged Argentine/Chilean border in the far southern Andes Mountains offers numerous, dramatic examples of both erosional processes and features of ice and water. The sharp, glaciated crest of the Cerro San Lorenzo (center) exceeds 12,000 feet and casts a long shadow southeastward. Glaciers on its western flank flow into the valley. Lago Pueyrredon, and the other lakes visible here, have been excavated by geologically "recent" episodes of glacier erosion, when glaciers extended all the way onto the lowland plains (top right). Since the last melting of the glaciers, scientists estimate about 15,000 years ago, three distinct "fan-deltas" have formed where rivers flow into the lake. Counterclockwise currents in the lake, driven by strong winds from the west, have generated thin sand spits from each fan-delta. The largest spit (attached to the largest fan-delta, see right arrow) has isolated an approximately 10-kilometer long segment of the south end of the lake. This river, which has constructed the large fan, presently discharges turbid water to this isolated basin, giving it a lighter color than the rest of the lake. This Digital Still Camera photo was taken from the International Space Station, in December 2000 (late spring for this part of the world) when most of the previous winter's snow had melted below an altitude of 6,000 feet. Little evidence of man's presence can be found in this rough, desolate region. Glacial data collected over the past 50 years indicate that small ice bodies are disappearing at accelerated rates. (EOS, vol 81, no. 24, June 13, 2000) Predictions are that large fluctuations in land ice, with significant implications to society, are possible in the coming decades and centuries due to natural and anthropogenic climate change. Before glacial data can be used to address critical problems pertaining to the world's economic and environmental health, more detailed information about such glaciers is needed. Images like this from the International Space Station can be added to those taken from satellites (Landsat-7, instruments on the Terra satellite launched in 1999) to build data sets of glaciers in remote areas around the world.

Yosemite National Park

Naked summits alternate with forested lowlands in Yosemite Valley, part of California’s Yosemite National Park. During the Pleistocene Ice Age, glaciers sculpted the underlying rocks in this region, leaving behind canyons, waterfalls, rugged peaks, and granite domes. As the ice retreated, forests grew, but forests only extend as high as 2,900 meters (9,500 feet) above sea level. Above the tree line are rocky landscapes with sparse alpine vegetation. So from the sky, Yosemite Valley appears as a light-and-dark patchwork of forest, rock, and shadow. The Enhanced Thematic Mapper Plus on NASA’s Landsat 7 satellite captured this true-color image of part of Yosemite Valley on August 18, 2001. The valley runs roughly east-west, and tall granite peaks lining the valley’s southern side cast long shadows across the valley floor. On the valley’s northern side, steep slopes appear almost white. Along the valley floor, roadways form narrow, meandering lines of off-white, past parking lots, buildings, and meadows. On the north side of Yosemite Valley is El Capitan. Shooting straight up more than 915 meters (3,000 feet) above the valley floor, El Capitan is considered the largest granite monolith in the world. This granite monolith sits across the valley from Bridalveil Fall, one of the valley’s most prominent waterfalls.
