Tibetan Braid
540 x 359 JPEG
Published December 16, 2001
On October 13, 2000, the Expedition 3 crew of the International Space Station, high over Tibet, took this interesting photo of the Brahmaputra River. This mighty Asian river carves a narrow west-east valley betweenthe Tibetan Plateau to the north and the Himalaya Mountains to the south, as it rushes eastward for more than 1500 kilometers in southwestern China. This 15-kilometer stretch is situated about 35 kilometers south of the ancient Tibetan capital of Lhasa where the river flow becomes intricately braided as it works and reworks its way through extensive deposits of erosional material. This pattern is indicative of a combination heavy sediment discharge from tributaries and reduction of the river’s flow from either a change in gradient or perhaps even climate conditions over the watershed.

Brüggen Glacier, Chile
540 x 405 JPEG
Published December 9, 2001
Brüggen Glacier in southern Chile is the largest western outflow from the Southern Patagonian Ice Field and, unlike most glaciers worldwide, advanced significantly since 1945. From 1945 to 1976, Brüggen surged 5 km across the Eyre Fjord, reaching the western shore by 1962 and cutting off Lake Greve from the sea.

Red colors of the aurora are dominant in this image captured by a digital still camera in September 2001. Auroras are caused when high-energy electrons pour down from the Earth’s magnetosphere and collide with atoms. Red aurora occurs from 200 km to as high as 500 km altitude and is caused by the emission of 6300 Angstrom wavelength light from oxygen atoms.

Chetumal Bay Coral Reef

Published October 28, 2001
Chetumal Bay lies on the Border between Mexico and Belize. To the east of the bay, Ambergris Cay connects the Belize Barrier Reef to the Yucatan Peninsula. The north of the island is Bacalar Chico Marine Reserve. Here, the barrier reef comes very close to the east side of the island. In 1998, reefs in Belize were hit by two major events that led to heavy coral mortality: El Niño-related coral bleaching and Hurricane Mitch.

"Boilers" along the southeast coast of Bermuda
Published September 30, 2001
Along the south shore of Bermuda, waves break continuously along algal/vermetid reefs (composed of algae and molluscs, not coral), forming “boilers.” Boilers are named because the continuous breaking of waves makes it look as if the sea is boiling. This photograph taken from the International Space Station shows the eastern half of the main islands of Bermuda. Land use is about 6 percent cropland, 55 percent developed and 34 percent rural. Reflective white-colored areas are buildings and other developments surrounded by green areas of vegetation. St. David’s Island is also home to the airport, with runways built out into Castle Harbour.

Manhattan

Published August 12, 2001
It was a fine spring day on April 28, 2001, in New York City when the Expedition 2 crew of Space Station Alpha acquired this digital photograph. This ESC image was taken of Manhattan using an 800 mm lens (see inset) from an orbit altitude of 383 km. This particular lens can achieve spatial resolutions less than 6 meters.
