PIX4672775: The Bahamas satellite views - Satellite image of the Bahamas - The Bahamas viewed by the Aqua satellite on 12 February 2009. East of southern Florida, large swaths of ocean water glow peacock blue. These waters owe their iridescence to their shallow depths. Near Florida and Cuba, the underwater terrain is hilly, and the crests of many of these hills including the islands of the Bahamas. On February 12, 2009, relatively clear skies allowed the Moderate Resolution Imaging Spectroradiometer (MODIS) on Nasa's Aqua satellite an unobstructed view of the region. The most striking feature of this image is the Great Bahama Bank, a massive underwater hill underlying Andros Island in the west, Eleuthera Island in the east, and multiple islands in between. To the north, another bank underlies another set of islands, including Grand Bahama. The varied colors of these banks suggest their surfaces are somewhat uneven. The banks' distinct contours, sharply outlined in dark blue, indicate that the ocean floor drops dramatically around them. In fact, over the banks, the water depth is often less than 10 meters (33 feet), but the surrounding basin plunges to depths as low as 4,000 meters (13,100 feet) / Bridgeman Images

Image taken from the International Space Station (ISS) on September 28, 2009. The north is downstairs. The Highland Valley Copper mine is the largest open pit copper mine in Canada, located near Logan Lake, British Columbia.

PIX4672451: Malaspina Glacier, Alaska. 08/1989 - Malaspina Glacier, Alaska, U.S.A. August 1989 - Malaspina Glacier, Alaska, observes from Space Shuttle Columbia. Malaspina Glacier can be seen just left of the center of this northeast - looking, low - oblique photograph. Located in southern Alaska on the shore of the Gulf of Alaska, Malaspina Glacier is a classic example of a piedmont glacier lying at the foot of a mountain range - - in this case, the Saint Elias Mountains (just north of the glacier). The glacier covers an area of 1500 square miles (3900 square kilometers) on the coastal plain, is almost 60 miles (97 kilometers) long, and is more than 1000 feet (300 meters) thick. The Seward Ice Field is the main source of ice for the glacier. The glacier moves in surges that push earlier - formed moraines outward into expanding concentric patterns, which you can see along the flanks of the ice mass. To the northwest of Malaspina Glacier is the curved and pointed Agassiz Glacier, which is also fed by the Seward Ice Field. To the northeast of Malaspina Glacier, located at the head of Yakutat Bay, is the Hubbard Glacier, which surged in 1989, blocking the entrance to Russell Fiord and temporarily trapping a large number of marine animals / Bridgeman Images
PIX4672500: Glacier Hubbard - Alaska - Close up view face 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
PIX4677507: Eruption de la Soufriere - Ile de Montserrat - Volcanic eruption of Soufriere Hills - Montserrat - Eruption of the Soufriere volcano on the island of Montserrat in the Caribbean, seen from the International Space Station (ISS) on October 11, 2009. The Soufriere Hills, a volcano on the island of Montserrat, in the Lesser Antilles island chain in the Caribbean Sea, has been active since 1995. This oblique astronaut photograph from the International Space Station (ISS) captures a white-to-gray ash and steam plume extending westwards from the volcano on October 11, 2009. While much of the island is covered in green vegetation, gray deposits that include pyroclastic flows and volcanic mudflows (lahars) are visible extending from the volcano towards the coastline. The silver-gray appearance of the Caribbean Sea surface is due to sunglint, which is the mirror-like reflection of sunlight off the water surface back towards the handheld camera onboard the ISS. The sunglint highlights surface wave patterns around the island / Bridgeman Images
