Challenges exist in understanding the consequences of    these changes on the inorganic carbon system in this ecologically important    and highly productive ecosystem. Distributions of dissolved inorganic    carbon (C<sub>T</sub>), total alkalinity (A<sub>T</sub>) and nutrients    revealed key physical, biological and biogeochemical controls of the    calcium carbonate saturation state (Ω<sub>aragonite</sub>) in different    water masses across the WAP shelf during the summer. Biological productionin spring and summer dominated changes in surface water Ω    <sub>aragonite</sub> (ΔΩ<sub>aragonite</sub> up to +1.39; <b>~</b>90%)    relative to underlying Winter Water. Sea-ice and glacial meltwaterconstituted a minor source of A<sub>T</sub> that increased surface water Ω    <sub>aragonite</sub> (ΔΩ<sub>aragonite</sub> up to +0.07; <b>~</b>13%).    Remineralization of organic matter and an influx of carbon-rich brines led    to cross-shelf decreases in Ω<sub>aragonite</sub> in Winter Water and    Circumpolar Deep Water. A strong biological carbon pump over the shelf    created Ω<sub>aragonite</sub> oversaturation in surface waters and    suppression of Ω<sub>aragonite</sub> in subsurface waters. Undersaturation    of aragonite occurred at < ~1000 m. Ongoing changes along the WAP will    impact the biologically driven and meltwater-driven processes that    influence the vulnerability of shelf waters to calcium carbonate    undersaturation in the future.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Calcium carbonate saturation states along the West Antarctic Peninsula","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":"alkalinity; aragonite; Circumpolar Deep Water; inorganic carbon system; meltwater","OtherDescriptors":null,"Notes":null,"AnaPub":2021,"MonPub":null,"DateUpdate":"2022-02-03","DateCreate":"2021-11-02","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000737585000001","VABBcode":null,"OpenAcc":1,"DOI":"10.1017/s0954102021000456"},"refs":null,"anarec":{"AnaID":347206,"PubliDate":2021,"Pagination":"575-595","XtraPublOfAnaID":null,"ISBN":null,"Volume":"33","Issue":"6","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45043,"SerRR":"Antarctic Science.
