Jökulsárlón is in southeast Iceland. Jökulsárlón literally means glacier lagoon (Jökull - glacier, lón - lagoon). At the time when first settlers arrived in Iceland, the edge of Breiðamerkurjökull, an outlet glacier of the great glacier Vatnajökull, is thought to have been 20km further north than it is now. The climate began to cool in about the year 1200, the cold spell reaching a peak in the period 1600-1900, which is sometimes known as the "Little Ice Age". As a result the glacier advanced until about 1890, reaching a point only about 1km from the coast at Jökulsá river. The eastern part of the glacier eroded the sediments of Breiðamerkursandur to a depth of up to 300m below sea level, the sediment being carried forward by the river Jökulsá. Without the river the glacier could not have eroded such a deep basin, because it is the river that carries the sediment to the sea.The warm period from 1920 to 1965 caused great changes in Breiðamerkurjökull glacier. It retreated very quickly, leaving a lagoon up to 190m deep where the glacier snout had been, and several kilometers of glacial moraines were exposed on both sides of the lagoon. The lagoon grew from 8km² in 1975 to 15km² in 1998. Large blocks of ice break off the edge of the glacier, which is about 30m high, keeping the lagoon stocked with icebergs.The lagoon, when frozen, was used in the 2002 James Bond film, Die Another Day, for a BMW chase scene.
