The fluxes that arise from the Great Ice Sheets are also modelled. Terrestrial HCO<sub>3</sub><sup>-</sup> fluxes decrease during deglaciation, largely because of the reduction in the area of the continental shelves as sea level rises. The HCO<sub>3</sub><sup>-</sup> fluxes, and the inferred consumption of atmospheric CO<sub>2</sub> are used as inputs to a carbon cycle model that estimates their impact on atmospheric CO<sub>2</sub> concentrations (<sup>atms</sup>CO<sub>2</sub>). A maximum perturbation of <sup>atms</sup>CO<sub>2</sub> by <img src=\"http://www.sciencedirect.com/scidirimg/entities/223c.gif\" alt=\"not, vert, similar\" border=0>5.5 ppm is calculated. The impact of solutes from glaciated terrain is small in comparison to those from non-glaciated terrain. Little variation in terrestrial Si and Ge fluxes is calculated (<10%). However, the global average riverine Ge/Si ratio may be significantly perturbed if the glacial Ge/Si ratio is high. At present, variations in terrestrial chemical erosion appear to have only a reduced impact on <sup>atms</sup>CO<sub>2</sub>, and only little influence on the global Si and Ge cycle and marine Ge/Si ratios during deglaciation.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Modelled glacial and non-glacial HCO<sub>3</sub><sup>-</sup>, Si and Ge fluxes since the LGM: little potential for impact on atmospheric CO<sub>2</sub> concentrations and a potential proxy of continental chemical erosion, the marine Ge/Si ratio","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":"    HCO3-, Si and Ge fluxes;     LGM;     atmospheric CO2 concentration;     marine Ge/Si ratio","OtherDescriptors":null,"Notes":null,"AnaPub":2002,"MonPub":null,"DateUpdate":"2018-05-17","DateCreate":"2006-11-27","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000176800800012","VABBcode":"vabb:79426","OpenAcc":0,"DOI":"10.1016/S0921-8181(02)00067-X"},"refs":null,"anarec":{"AnaID":105572,"PubliDate":2002,"Pagination":"139-153","XtraPublOfAnaID":null,"ISBN":null,"Volume":"33","Issue":"1-2","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42934,"SerRR":"Global and Planetary Change.
