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.

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.

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.

East of Galveston, Texas, a thin barrier beach—Bolivar Peninsula—stretches along the coastline. On the far eastern end of Bolivar Peninsula is High Island, so named for the salt dome that boosts the area some 11.6 meters (38 feet) above the rest of the Gulf Coast. After Hurricane Ike passed, rescuers combed through the destroyed communities along Bolivar Peninsula. Thanks to its elevation, High Island fared better than other parts of the Peninsula.

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.
