An intricate maze of small lakes and waterways define the Yukon Delta at the confluence of Alaska's Yukon and Kuskokwim Rivers with the frigid Bering Sea. Wildlife abounds on the delta and offshore where sheets of sea ice form during the coldest months of the year.
Earth as Art 2
Forty-five new scenes developed for their aesthetic beauty, rather than for scientific value. The artists of this collection come from three sensors aboard satellites orbiting the Earth - Landsat 7, ASTER, and MODIS.
A giant whirlpool cloud, coaxed into shape by high-altitude winds, swirls above the sea between Spain and Morocco.
Western Asia, the world's largest continent, occupies one-third of the Earth's landmass. Although divisions are somewhat arbitrary, Western Asia encompasses the Middle East and countries that surround the Caspian Sea, including Kazakhstan and Russia.
As air flows over and around objects in its path, spiraling eddies, known as Von Karman vortices, may form. The vortices in this image were created when prevailing winds sweeping east across the northern Pacific Ocean encountered Alaska's Aleutian Islands.
Steep-sided volcanic cones along the Chilean-Argentinean border add texture to this "study in blues." Of approximately 1,800 volcanoes scattered across this region, 28 are active.
Valley glaciers appear as fingers of blue ice reaching out from the Vatnajokull Glacier in Iceland's Skaftafell National Park. The park lies on southern edge of Vatnajokull, Europe's largest ice cap.
Elusive, but ecologically vital, Namibia's Ugab River only flows above ground for a few days each year. The subterranean waters underlying this ephemeral river, however, are shallow enough in places to fill hollows and sustain a wildlife population that includes the rare desert elephant.
Between the fertile Euphrates River valley and the cultivated lands of the eastern Mediterranean coast, the Syrian Desert covers parts of modern Syria, Jordan, Saudi Arabia, and Iraq.
France's famed Provence region meets the Mediterranean as a gentle curve intricately sculpted into sheltered bays and fringing peninsulas. The ancient port of Marseilles, the country’s second largest city, nestles in the large bay at the lower left corner of the image.
South America stretches more than 7,500 kilometers from the warm Caribbean Sea almost to Antarctica. Waters from the eastern slopes of the Andes Mountains drain into mighty rivers, such as the Amazon, that traverse rain forests, grassy plains, and dry plateaus to eventually reach the Atlantic Ocean.
