During the survey, cyclical warming and cooling strongly influenced the physical, chemical, and thermodynamic properties of the ice cover. Two sampling sites with contrasting characteristics of ice and snow thickness were sampled: one had little snow accumulation (from 8 to 25 cm) and larger temperature and salinity variations than the second site, where the snow cover was up to 38 cm thick and therefore better insulated the underlying sea ice. We show that each cooling/warming event was associated with an increase/decrease in the brine salinity, total alkalinity (TA), total dissolved inorganic carbon (<i>T</i>CO<sub>2</sub>), and in situ brine and bulk ice CO<sub>2</sub> partial pressures (<i>p</i>CO<sub>2</sub>). Thicker snow covers reduced the amplitude of these changes: snow cover influences the sea ice carbonate system by modulating the temperature and therefore the salinity of the sea ice cover. Results indicate that <i>p</i>CO<sub>2</sub> was undersaturated with respect to the atmosphere both in the in situ bulk ice (from 10 to 193 µatm) and brine (from 65 to 293 µatm), causing the sea ice to act as a sink for atmospheric CO<sub>2</sub> (up to 2.9 mmol m<sup>-2</sup> d<sup>-1</sup>), despite supersaturation of the underlying seawater (up to 462 µatm).","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Sea ice <i>p</i>CO<sub>2</sub> dynamics and air-ice CO<sub>2</sub> fluxes during the Sea Ice Mass Balance in the Antarctic (SIMBA) experiment - Bellingshausen Sea, Antarctica","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":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2014,"MonPub":null,"DateUpdate":"2015-06-01","DateCreate":"2015-05-21","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000347468000025","VABBcode":null,"OpenAcc":1,"DOI":"10.5194/tc-8-2395-2014"},"refs":null,"anarec":{"AnaID":247063,"PubliDate":2014,"Pagination":"2395-2407","XtraPublOfAnaID":null,"ISBN":null,"Volume":"8","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":216569,"SerRR":"The Cryosphere.
