Until now, most attention has focused on dissolution in the deep sea, while dissolution in coastal and shelf environments remains poorly constrained. Here, we present a synthesis of CaCO<sub>3</sub> dissolution rates in sediments of coastal and shelf environments and integrate them into an updated global marine CaCO<sub>3</sub> budget. The highest areal dissolution rates occur in coral reefs and lagoons, and in seagrass-dominated banks and bays, as these sediments combine high amounts of soluble high-magnesium calcite with deep oxygen penetration and high organic matter input that facilitate dissolution. Nevertheless, carbonate-poor shelves contribute as much (∼45%) as coral reefs and lagoons to global coastal and shelf carbonate dissolution. Total coastal and shelf dissolution is estimated at 11&nbsp;±&nbsp;9&nbsp;Tmol&nbsp;yr<sup>−1</sup> and thus provides ∼8% of the total CaCO<sub>3</sub> dissolution in the ocean. Combining these dissolution rates with published estimates of production, terrestrial input, and burial, mass balance closure requires an off-shelf lateral export of ∼15&nbsp;Tmol CaCO<sub>3</sub> yr<sup>−1</sup>. Although this estimate carries large uncertainty (&gt;100%), it suggests that a significant fraction of the CaCO<sub>3</sub> produced on the shelf is transferred from a short-term climate buffer in the shelf seafloor to a long-term climate buffer in the deep-sea seafloor.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"A revised estimate of calcium carbonate dissolution in coastal and shelf sediments suggests large shelf exports in the marine CaCO<sub>3</sub> cycle","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-04-21 01:33:44.398569","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":"carbonate dissolution; carbonate cycle; coastal and shelf sediment","OtherDescriptors":null,"Notes":null,"AnaPub":2026,"MonPub":null,"DateUpdate":"2026-03-30","DateCreate":"2026-03-30","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:001720780200001","VABBcode":null,"OpenAcc":1,"DOI":"10.1029/2025gb008936"},"refs":null,"anarec":{"AnaID":438447,"PubliDate":2026,"Pagination":"e2025GB008936","XtraPublOfAnaID":null,"ISBN":null,"Volume":"40","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45841,"SerRR":"Global Biogeochemical Cycles.
