View from space of the Mataiva Atoll, the westernmost atoll of the Tuamotu Archipelago, part of French Polynesia. Mataiva Atoll is notable in that its central lagoon includes a network of ridges (white, image center) and small basins formed from eroded coral reefs. Mataiva means "nine eyes" in Tuamotuan, an allusion to nine narrow channels on the south-central portion of the island.
