Berlengas Archipelago, Portugal39.3N 9.3W
Water currents create rippled patterns off the coast of Portugal near the Berlengas archipelago, a group of very small islands visible in this orthorectified image.
The archipelago has no permanent population, as it has been declared a reservation area due to the local fauna (mostly seabirds). It is only visited by scientists and, in the summer, by a small number of tourists.
The largest island is known as Berlenga Grande. It is 1500 meters long by 800 meters wide and 85 meters high. There are beaches and several caves on this island; its waters are very clean and have barrier reefs and vibrant marine life.
