Analysis of information sources in references of the Wikipedia article "Jökulsárlón" in English language version.
A century ago there was no lagoon, and this spot was under 100 feet of glacial ice. The glacier, the Breidamerkurjokull, extended to within 250 yards of the ocean. Now the Atlantic is more than two miles away from the glacier's massive, miles-wide snout, which stands in an expanding lake of its own melt water. Jokulsarlon — "glacier lake" in Icelandic — is now more than 350 feet deep and has more than doubled its size in the past 15 years, threatening to wash out Iceland's principal highway.
