The sunny south of Spain offers more to the national economy than simply tourism. Over the past 50 years, the small coastal plain (campo), some 30 kilometers southwest of the city of Almería, has been intensively developed for agriculture. An estimated 20,000 hecatres of extra-early market produce is grown in greenhouses in the Campo de Dalías.

On May 18, 1980, Mount Saint Helens volcano erupted. Because the eruption occurred in an easily accessible region of the U.S., Mount St. Helens has provided unprecedented opportunities for U.S. researchers to collect scientific observations of the geology of an active volcano and document the regional ecological impact and recovery from an eruption.

This metropolis of 15 million people occupies both sides of the entrance to the narrow, 20-mile long Bosporus Strait connecting the Mediterranean and Sea of Marmara (south) to the Black Sea (north). From its founding as Byzantium by the Greeks in 600 B.C., this strategically located city has been a focus of maritime trade and commerce as well as an outpost and threshold for cultural exchange and conflict between Europe and Asia. This digital camera image was taken by the crew of the International Space Station on April 16, 2004. When this image was taken, strong currents carried turbid coastal waters from the Black Sea through the Strait and into the Sea of Marmara.

On April 26, 1986, the world’s worst nuclear power accident occurred at the Chernobyl Nuclear Power Plant near the Ukrainian-Belarus border. Toxic radionuclides like Cs137 and Sr90 contaminated an area of 155,000 square kilometers in what is today Belarus, Ukraine and Russia. Hundreds of thousands of people were killed, sickened from radiation-induced illnesses, or resettled to uncontaminated land. This image, taken from the Russian Mir spacecraft, shows Chernobyl and the surrounding countryside.

Kyiv is rich in the history of western civilization. It was a trade center on the Baltic-Black Sea route in the 11th and 12th centuries, and one of the major cities in the Christian world, until Mongol invaders destroyed the city in 1240. Some of the 11th-century cathedrals, which contain famous artifacts, remain standing and have been restored.

The Betsiboka Estuary on the northwest coast of Madagascar is the mouth of Madagascar’s largest river and one of the world’s fast-changing coastlines. Nearly a century of extensive logging of Madagascar’s rainforests and coastal mangroves has resulted in nearly complete clearing of the land and fantastic rates of erosion. After every heavy rain, the bright red soils are washed from the hillsides into the streams and rivers to the coast. Astronauts describe their view of Madagascar as “bleeding into the ocean.” One impact of the extensive 20th century erosion is the filling and clogging of coastal waterways with sediment—a process that is well illustrated in the Betsiboka estuary. In fact, ocean-going ships were once able to travel up the Betsiboka estuary, but must now berth at the coast.

Astronauts on board the International Space Station (ISS) have a unique view of the world because of their position in a low orbit (200 nautical miles, 360 kilometers) relative to satellites and their ability to look at any angle out the windows of the spacecraft. ISS crewmembers recently took advantage of their vantage point to photograph a series of oblique views of the Himalayas looking south from over the Tibetan Plateau. At first glance, one might think that the image looks like a picture taken from an airplane, until you remember that the summits of Makalu (left, 8,462 meters, or 27,765 feet) and Everest (right, 8,850 meters, or 29,035 feet) are at the heights typically flown by commercial aircraft. The full mosaic covers over 130 kilometers (80 miles) of the Himalayan front, and could never be seen this way from an airplane.

In January, 2004, astronauts on board the International Space Station took this detailed picture of melt water pooled on the surface of iceberg A-39D, a 2-kilometer wide, 11-kilometer long iceberg and drifting near South Georgia Island. The different intensities of blue are interpreted as different water depths. From the orientation of the iceberg, the deepest water (darkest blue) lies at the westernmost end of the iceberg. The water pools have formed from snowmelt—late January is the peak of summer in the Southern Hemisphere.

The striking land use pattern, seen through a high magnification lens and highlighted by winter snow and low Sun angles, produces a unique view of the village of Argudan near the north slopes of the Greater Caucasus Mountains. The image was taken with a handheld camera from the International Space Station in the early afternoon of December 20, 2003. This rural, agricultural community sits astride the main highway about 15 kilometers east-southeast of the city of Nalchik. Shadows from a line of trees planted as a windbreak near the highway give the road a ragged appearance. A small stream flowing northeastward exits heavily forested foothills through the village and fields of intensely cultivated croplands on the plains. Snow falls through the vegetation, making the woodlands appear extremely dark compared to the snow-covered fields. Astronauts also photographed nearby Nalchik, a tourist resort and industrial center. It is the major city of the Kabardino-Balkar Republic (population around 750,000), one of five small republics on the north slopes of the Caucasus Mountains, 200 kilometers west of Chechnya.

From a vantage point about 360 km (225 miles) over the Earth, Space Station crewmembers photographed the crescent moon through the upper layers of Earth’s atmosphere. At the bottom of the image, a closed deck of clouds is probably at about 6 km (3 miles). The shades of blue grading to black are caused by the scatter of light as it strikes gas molecules of the very low density upper atmosphere.

Chile’s Bíobío River flows northwestward from the high Cordillera of the Andes to the Pacific Ocean near Concepción, about 450 kilometers south of Santiago. The river is known globally for spectacular white-water rafting. This image shows a section of the river that skirts around Callaqui volcano in the Andes, and features the Pangue Dam and reservoir filling a narrow, meandering segment of the Bíobío River valley. Completed in 1996, the dam is the first of six hydroelectric dams planned by ENDESA, a Chilean utility company. The future development of the Bíobío River is a point of intense debate among Chileans, and has been called Chile’s “defining environmental issue.”

For the crew onboard the International Space Station daylight views of the Earth’s Southern Hemisphere offer fewer opportunities to observe and document land features with onboard cameras. However, South America’s Patagonian Ice Fields and glaciers in the far southern Andes mountains offer beautiful, dynamic features with frequent passes whenever weather conditions permit. On the afternoon of January 3, 2004, the crew took this view of the Upsala Glacier in Argentina. A worldwide retreat of glaciers was observed during the twentieth century and most of the Patagonia’s glaciers, including Upsala, were no exception.

These photographs, taken from the International Space Station in January, 2004, show two pieces of a massive iceberg that broke off from the Ronne Ice Shelf in October, 1998. The pieces of iceberg A-38 have floated relatively close to South Georgia Island. After 5 years and 3 months adrift, they are approximately 1,500 nautical miles from their origin. In the oblique image, taken a few minutes later, the cloud pattern reveals the impact of the mountainous islands on the local wind field. At this time, the icebergs are sheltered in the lee side of the island.

Great Salt Lake serves as a striking visual marker for astronauts orbiting over North America. A sharp line across its center is caused by the restriction in water flow from the railroad causeway. The eye-catching colors of the lake stem from the fact that Great Salt Lake is hypersaline, typically 3–5 times saltier than the ocean, and the high salinities support sets of plants and animals that affect the light-absorbing qualities of the water. Space Station astronauts have recorded the decline in lake levels in response to a regional 5-year drought taking both detailed views and broad views of the entire lake. As lake levels have declined the salt works have become islands in the middle of a dry lakebed.

Looking out the window of the International Space Station, astronauts often take the time to admire and photograph tropical islands and coral reefs. From an altitude of 400 kilometers and with only a digital camera as a tool, it seems impossible to make detailed measurements of the depth of underwater features. However, a new technique developed by NOAA scientists has done just that—plotted the depths of lagoon features at Pearl and Hermes Reef, northwest Hawaii, using digital astronaut photography from the International Space Station (ISS).

The South Atlantic Ocean off the coast of Argentina and Uruguay is a rich mixing bowl of different water masses. The nutrient-rich waters from the combined Paraná and Uruguay Rivers empty into the South Atlantic through the Rio de la Plata. Under the right conditions, especially in spring and early summer, the nutrients fertilize the offshore surface waters allowing for large plankton blooms. This unique image captures traces of several different water masses just southeast of Montevideo, Uruguay, and the Rio de la Plata. Close to the coast of Uruguay, the muddy fresh water plume snakes along the coast. Farther offshore, broad swirls of light blue-green and darker water mark a bloom of plankton. To the right, deep blue water covered by puffy clouds suggests another, warmer water mass just north of the bloom.
