Kharg Island is Iran’s primary oil export terminal in the Persian Gulf. This rocky limestone island is unique because it is one of the few islands in the Persian Gulf with freshwater which has collected within the porous limestone. In addition to its commercial and strategic importance, the freshwater has biological importance, supporting populations of gazelles. This high-resolution photograph taken by astronauts on board the International Space Station shows detail of the tanker dock facilities, tanks and other infrastructure. Sunglint on the surface of the water highlights small amounts of oil on the sea surface and reveals the direction of the local currents.

On September 25, 2002, astronauts aboard the International Space Station viewed Easter Island, one of the most remote locations on Earth. Easter Island is more than 2000 miles from the closest populations on Tahiti and Chile—even more remote than astronauts orbiting at 210 nautical miles above the Earth. Archaeologists believe the island was discovered and colonized by Polynesians at about 400 AD. Subsequently, a unique culture developed. The human population grew to levels that could not be sustained by the island. A civil war resulted, and the island’s deforestation and ecosystem collapse was nearly complete.

The ghostly white shapes northeast and immediately southwest of Wrangel Island are sea ice. Over the course of the satellite record, Arctic sea ice has advanced and retreated past Wrangel Island many times. From 1979 to 2000, the sea ice edge at the end of summer generally fell somewhere in the vicinity of Wrangel Island, but this is not the first summer when the sea ice edge has retreated well north of the island.

Named Isla de Aves in Spanish, (meaning “Island of the Birds”) Aves Island lies west of the Lesser Antilles in the Caribbean. It provides a nesting site to green sea turtles (Chelonia mydas) and, of course, birds. Because the abundant bird droppings, known as guano, could be used in fertilizer and gunpowder, guano miners worked on the island until they depleted the supply. Since its discovery by Europeans, likely in the late 16th century, Aves Island was subsequently claimed by several European nations. The island is currently claimed by Venezuela, although disputes about ownership of the island, and the surrounding exclusive economic zone in the Caribbean, continue today.

Akpatok Island lies in Ungava Bay in northern Quebec, Canada. Accessible only by air, Akpatok Island rises out of the water as sheer cliffs that soar 500 to 800 feet (150 to 243 m) above the sea surface. The island is an important sanctuary for cliff-nesting seabirds.
