Watery Gem of Northern Italy, the City of Venice
Published July 8, 2001
The compact Italian city of Venice with its renowned canals is situated on a small, fish-shaped island in the Laguna Veneta at the northwest corner of the Adriatic Sea. In this photo taken from the International Space Station by the Expedition 1 Crew on February 21, 2001, one can see part of the causeway connecting the city to the mainland. The sinuous Canal Grande bisecting the city is easily visible in this scene as is the larger Canal Giudecca to the west, which leads to the port facilities on the northwestern end of the island. For centuries, the low-lying city has successfully coped with the three-foot tidal range experienced at this end of the Adriatic Sea, and the series of barrier islands has offered some protection from storm waves. However, a combination of both regional land subsidence and recent slight rises in sea level pose a significant threat this historic city and its priceless art treasures.

Mount Ararat (Agri Dagi), Turkey
Published June 17, 2001
Mount Ararat (16,940 feet; 5165 meters) is the largest volcano in Turkey. Although not currently active, its most recent eruption has probably been within the last 10,000 years. It is located in extreme northeastern Turkey, near the borders with Iran and Armenia. Southwest of the main peak lies Little Ararat (12,877 feet; 3896 meters). Ahora Gorge is a northeast-trending chasm dropping 6000 feet from the top of the mountain and was the focus of a major earthquake in 1840. A number of claims by different explorers to have found remnants of Noah’s Ark on Mt. Ararat have led to continuing expeditions to the mountain, many of which have focused their searches on the gorge area.

Egypt’s North Sinai Agricultural Development
Published June 10, 2001
This time series of photographs of the Mediterranean coast near the Suez Canal shows ten years of changes associated with two of Egypt’s “Mega” Development Projects. At the mouth of the canal, a large auxiliary channel has been formed as part of a new central hub port and industrial zone, known as the East Port-Said Project. Further south, the effects of the Al-Salam (El Salam or “Peace”) Canal and North Sinai Agricultural Development Program can be seen as desert is converted to irrigated agriculture.

Niagara Falls
Published May 20, 2001
The Niagara River forms the U.S.-Canadian Border and allows Lake Erie to drain northwest into Lake Ontario. Lake Ontario is about 100 m lower than Lake Erie; the Falls and the rapids account for most of the elevation difference. The energy derived from water falling over the falls, with average total flows of 750,000 U.S. gallons (2.8 million liters) per second, fuel multiple power plants on the river. Power Plants downstream from the plant generate 4.4 million kilowatts of power for both Ontario and New York.

Salt Evaporation Ponds, Dead Sea
Published May 13, 2001
The complex of Jordanian salt evaporation ponds at the southern end of the Dead Sea has expanded significantly over the past dozen years. The western margin of the salt ponds marks the Jordan-Israel border. In August 1989, when the crew of Space Shuttle mission STS-28 photographed the region, the northern extension did not exist and the large polygonal ponds in the northwestern and northeastern sectors had not been subdivided. In the view taken by the STS-102 crew in March 2001, one can see that there has also been expansion at the southeastern end, and that levees now segment the northeastern wedge into four ponds.

Gobi Dust Over Northeast China and Korea
Published May 6, 2001
Dust blowing off the Gobi desert eastward across the China toward the Pacific Ocean is a common event in April. Space Shuttle astronauts have photographed these dusts storms several times. These photographs, taken by astronauts on April 25, 1990, show a thick blanket of dust that entirely obscures the southern half of the Korean Peninsula. The dust is being transported from west (left) to east (right). The mountainous spine of the peninsula induces gravity waves in the dust cloud on the downwind (east) side.
