Concomitant measurements of wave-in-ice activity from the buoys are used to infer that the ice remained unconsolidated, and pancake ice conditions were maintained over at least the first 7 days. Analysis of the data shows (i) the fastest reported ice drift speeds in the Southern Ocean; (ii) high correlation of drift velocities with the surface wind velocities, indicating absence of internal ice stresses >100 km from the ice edge where remotely sensed ice concentration is 100%; and (iii) presence of a strong inertial signature with a 13 hr period. A Lagrangian free drift model is developed, including a term for geostrophic currents that reproduce the 13 hr period signature in the ice motion. The calibrated model provides accurate predictions of the ice drift for up to 2 days, and the calibrated parameters provide estimates of wind and ocean drag for pancake floes under storm conditions.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Drift of pancake ice floes in the winter Antarctic marginal ice zone during polar cyclones","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-06-08 01:31:31.332388","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"sea ice; marginal ice zone; drift; pancake ice; Antarctic; buoy","OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2023-03-30","DateCreate":"2023-03-30","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000534229400019","VABBcode":null,"OpenAcc":0,"DOI":"10.1029/2019JC015418"},"refs":null,"anarec":{"AnaID":362911,"PubliDate":2020,"Pagination":"e2019JC015418","XtraPublOfAnaID":null,"ISBN":null,"Volume":"125","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":272092,"SerRR":"Journal of Geophysical Research-Oceans.
