PIX4658455: Saudi Arabia's coral reefs - Al Wadj Bank, Saudi Arabia - Approximately 260 coral species have been recorded in Al Wadj Bank coral reefs in Saudi Arabia. Image obtained from the International Space Station (ISS) in December 2007. Saudi Arabia boasts the most coral reefs of any Middle Eastern country, as it includes coastline along both the Red Sea and the Gulf of Arabia. This high - resolution astronaut photograph shows part of the Al Wadj Bank, located along the northern Red Sea coast. Despite the relatively high salinity of Red Sea water, approximately 260 species of coral have been documented in the region. Large tracts of the Saudi Arabian coastline are undeveloped, and reefs in these areas are in generally good ecological health. However, reefs located near large urban centers such as Jeddeh have suffered degradation due to land reclamation (dredging and filling), pollution, and increased sediment runoff from land. The Al Wadj Bank (a bank is an underwater hill) includes a healthy and diverse reef system, extensive seagrasses beds, and perhaps the largest population of dugong - - a marine mammal similar to the North American manatee - - in the eastern Red Sea. The portion of the Bank in this image illustrates the complex form and topography of the reef system. Several emergent islands (tan) are visible, surrounded primarily by dark green seagrasset; the largest is at top left. Only the islands are above the waterline; over the reefs, the water color ranges from light teal (shallow) to turquoise (increasing depth). The southern edge of the reef is well defined by the deep, dark blue water of the Red Sea (top). Image taken from the international space station (ISS) in december 2007 / Bridgeman Images

PIX4672384: Condensation trains seen from ISS. - Contrails over Rhone valley seen from ISS. - Condensation trains caused by air traffic. Upstairs, Leman Lake. Image obtained from the International Space Station on May 15, 2002. This digital photograph taken through the windows of the International Space Station on May 15, 2002, shows condensation trails over the Rhone Valley. Condensation trails - - or contrails - - are straight lines of ice crystals that form in the wake of jet liners where air temperatures at altitude are lower than about - 40* C. Newer contrails are thin whereas older trails have widened with time as a result of light winds. Because of this tendency for thin contrails to cover greater areas with time, it is estimated that these artificial clouds”” cover 0.1% of the planet's surface. Percentages are far higher in some places such as southern California, the Ohio River Valley and parts of Europe, as illustrated here. / Bridgeman Images

PIX4672430: Glacier Malaspina, Alaska - The Malaspina Glacier in Alaska - Le Glacier Malaspina, Alaska, from perspective. This image is the result of joint observations made by the Landsat-7 satellite in August 2000 in visible and infrared, combined with elevation radar data obtained by the SRTM (Shuttle Radar Topography Mission) in February 2000. This glacier extends over 3000 km2. Natural colours have been applied to this image: light blue, ice, white, snow, green vegetation, grey rock and blue for the ocean. Malaspina Glacier in southeastern Alaska is considered the classic example of a piedmont glacier. Piedmont glaciers occur where valley glaciers exit a mountain range onto broad lowlands, are no longer laterally confined, and spread to become wide lobes. Malaspina Glacier is actually a compound glacier, formed by the merger of several valley glaciers, the most prominent of which seen here are Agassiz Glacier (left) and Seward Glacier (right). In total, Malaspina Glacier is up to 65 kilometers (40 miles) wide and extends up to 45 kilometers (28 miles) from the mountain front nearly to the sea. This perspective view was created from a Landsat satellite image and an elevation model generated by the Shuttle Radar Topography Mission (SRTM). Landsat views both visible and infrared light, which have been combined here into a color composite that generally shows glacial ice in light blue, snow in white, vegetation in green, bare rock in grays and tans, and the ocean (foreground) in dark blue. The back (northern) edge of the data set forms a false horizon that meets a false sky. Glaciers are sensitive indicators of climatic change / Bridgeman Images

PIX4672475: Bering Glacier, Alaska - Bering Glacier in Alaska - The Bering Glacier is the largest glacier in North America. Since 1900, the glacier front has receded 12 km. Image obtained by Landsat-7 satellite on 29 September 2002. Bering Glacier currently terminates in Vitus Lake south of Alaska's Wrangell - St. Elias National Park, about 10 km from the Gulf of Alaska. Combined with the Bagley Icefield, where the snow that feeds the glacier accumulates, the Bering is the largest glacier in North America. Warmer temperatures and changes in precipitation over the past century have thinned the Bering Glacier by several hundred meters. Since 1900 the terminus has retreated as much as 12 km. Most of the glaciers along the Alaskan coast are retreating along with the Bering Glacier. This true - color image of the Bering Glacier terminus was acquired on September 29, 2002, by the Enhanced Thematic Mapper plus (ETM +) instrument aboard the USGS/NASA Landsat - 7 satellite / Bridgeman Images

PIX4672493: Hubbard Glacier - Alaska - Wide view of Hubbard Glacier - Alaska - The Hubbard Glacier is the longest glacier in North America leading to the sea. Hubbard Glacier, the largest tidewater glacier in the world. The Hubbard and Turner/Haenke Glaciers extend out into Disenchantment Bay (discovered and named by Captain Alejandro Malaspina in 1791, who was disappointed to find the inlet was a dead end). The face of Hubbard Glacier extends 6 1/2 miles in length. The towering ice peaks making up the face of the glacier are 400 to 500 feet high! To give some perspective the Wrangell - St. Elias mountain peaks in the background are all between 14,000 and 18,000 feet in elevation, the tallest coastal mountains in the world / Bridgeman Images
