Langeoog

Langeoog is one of the seven inhabited East Frisian Islands at the edge of the Lower Saxon Wadden Sea in the southern North Sea, located between Baltrum Island (west), and Spiekeroog (east). It is also a municipality in the district of Wittmund in Lower Saxony, Germany. The name Langeoog means Long Island in the Low German dialect.GeographyLangeoog's beach is 14km long. Langeoog's actual size depends on the level of tide, which rises and falls about 2.5m in 6 hours.Fresh water, where salt water is all aroundLangeoog is — seen with the geologist's eye — nothing but sand. Rainwater that drips into the sand has a lower density than saltwater, which makes a kind of freshwater bubble float over the saltwater surrounding and deep under the island.The beach and the dunes are eroded by the sea in the western part of the island. In the last 50 years Langeoog's western end has moved several hundred metres to the east. Things like this happen on every East Frisian island — some islands moved so far that the town had to be rebuilt several times. Every island except Juist and Langeoog has large concrete groynes at its western end.HistoryStorm TidesIn 1717 Langeoog was cut in three parts by the Christmas storm tide.
