President Calvin Coolidge proclaimed the area around Glacier Bay a national monument under the Antiquities Act on February 25, 1925. Subsequent to an expansion of the monument by President Jimmy Carter in 1978, the Alaska National Interest Lands Conservation Act (ANILCA) enlarged the national monument by 523,000 acres (2116.5&nbsp;km²) on December 2, 1980 and in the process created Glacier Bay National Park and Preserve, with 57,000 additional acres (230.7&nbsp;km²) of public land designated as national preserve to the immediate northwest of the park in order to protect a portion of the Alsek River and related fish and wildlife habitats while allowing sport hunting.</p>\n<p>Glacier Bay became part of a binational UNESCO World Heritage Site in 1979, was inscribed as a Biosphere Reserve in 1986 and in 1994 undertook an obligation to work with Hoonah and Tlingit Native American organizations in the management of the protected area. In total the park and preserve cover 5,130 square miles (13,287&nbsp;km²). Most of Glacier Bay is designated wilderness area which covers 4,164 square miles (10,784&nbsp;km²).</p>\n\n\n\n<!-- \nNewPP limit report\nParsed by mw1193\nCached time: 20150918141433\nCache expiry: 2592000\nDynamic content: false\nCPU time usage: 0.261 seconds\nReal time usage: 0.332 seconds\nPreprocessor visited node count: 1139/1000000\nPreprocessor generated node count: 0/1500000\nPost‐expand include size: 39542/2097152 bytes\nTemplate argument size: 1360/2097152 bytes\nHighest expansion depth: 18/40\nExpensive parser function count: 2/500\nLua time usage: 0.112/10.000 seconds\nLua memory usage: 4.16 MB/50 MB\nNumber of Wikibase entities loaded: 1-->\n\n<!-- \nTransclusion expansion time report (%,ms,calls,template)\n100.00% 313.143 1 - -total\n 64.78% 202.853 1 - Template:Infobox_Protected_area\n 62.09% 194.439 1 - Template:Infobox\n 16.34% 51.183 6 - Template:Cite_web\n 12.70% 39.761 1 - Template:Infobox_map\n 12.03% 37.669 1 - Template:Convert\n 10.64% 33.329 1 - Template:NPS_area\n 10.40% 32.554 1 - Template:Infobox_coord\n 10.19% 31.894 1 - Template:Location_map\n 8.62% 27.008 1 - Template:Coord\n-->\n</div><a href=\"http://en.wikipedia.org/wiki/Glacier Bay National Park and Preserve\" target=\"_blank\">Continua a leggere..</a>","title":"Glacier Bay National Park and Preserve"},{"id":"wk-2","pos":{"top":"11","left":"92"},"time":{"start":85,"end":95},"art":"Tidewater glacier cycle","lang":"en","wiki":"<div>\n<p>The <b>tidewater glacier cycle</b> is the typically centuries-long behavior of tidewater glaciers that consists of recurring periods of advance alternating with rapid retreat and punctuated by periods of stability.
