When implemented in coastal environments, olivine weathering is expected to increase seawater alkalinity, thus resulting in additional CO<sub>2</sub> uptake from the atmosphere. However, the mechanisms of marine olivine weathering and its effect on seawater–carbonate chemistry remain poorly understood. Here, we present results from batch reaction experiments, in which forsteritic olivine was subjected to rotational agitation in different seawater media for periods of days to months. Olivine dissolution caused a significant increase in alkalinity of the seawater with a consequent DIC increase due to CO<sub>2</sub> invasion, thus confirming viability of the basic concept of enhanced silicate weathering. However, our experiments also identified several important challenges with respect to the detailed quantification of the CO<sub>2</sub> sequestration efficiency under field conditions, which include nonstoichiometric dissolution, potential pore water saturation in the seabed, and the potential occurrence of secondary reactions. Before enhanced weathering of olivine in coastal environments can be considered an option for realizing negative CO<sub>2</sub> emissions for climate mitigation purposes, these aspects need further experimental assessment.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Olivine dissolution in seawater: implications for CO<sub>2</sub> sequestration through enhanced weathering in coastal environments","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-23 01:32:44.131447","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2017,"MonPub":null,"DateUpdate":"2021-05-17","DateCreate":"2017-05-01","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000398646500042","VABBcode":null,"OpenAcc":1,"DOI":"10.1021/acs.est.6b05942"},"refs":null,"anarec":{"AnaID":284784,"PubliDate":2017,"Pagination":"3960-3972","XtraPublOfAnaID":null,"ISBN":null,"Volume":"51","Issue":"7","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42837,"SerRR":"Environmental Science and Technology.
