During the past two decades, the sector ice discharge has increased 45-fold, the velocity regime has switched from predominantly slow (~ 10<sup>1</sup>?m/yr) to fast (~ 10<sup>3</sup>?m/yr) flow, and rates of ice thinning have exceeded 25?m/yr. At the time of widespread dynamic activation, parts of the terminus may have been near floatation. Subsequently, the imbalance has propagated 50?km inland to within 8?km of the ice cap summit. Our observations demonstrate the ability of slow-flowing ice to mobilize and quickly transmit the dynamic imbalance inland; a process that we show has initiated rapid ice loss to the ocean and redistribution of ice mass to locations more susceptible to melt, yet which remains poorly understood.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Rapid dynamic activation of a marine-based Arctic ice cap","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"ice cap; mass balance; Austfonna; dynamic instability; altimetry; InSAR","OtherDescriptors":null,"Notes":null,"AnaPub":2014,"MonPub":null,"DateUpdate":"2015-05-27","DateCreate":"2015-05-21","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000348916500030","VABBcode":null,"OpenAcc":1,"DOI":"10.1002/2014GL062255"},"refs":null,"anarec":{"AnaID":246809,"PubliDate":2014,"Pagination":"8902-8909","XtraPublOfAnaID":null,"ISBN":null,"Volume":"41","Issue":"24","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42920,"SerRR":"Geophysical Research Letters.
