Most pCO<sub>2</sub> measurements are made from ships, whose uncontaminated seawater intakes are located at >5‐m depth to prevent ingestion of air. However, there could be bias in determinations of CO<sub>2</sub> fluxes if there is disagreement between pCO<sub>2</sub> measurements at the surface and 5 m. Seawater measurements made at the near surface and 5 m in the eastern Equatorial Pacific Ocean show that precipitation can dilute surface seawater salinity and lower the pCO<sub>2</sub> and dissolved inorganic carbon and raise pH of the same water, and that these changes in ocean chemistry are largely missed by measurements at 5 m. This finding implies that estimates of ocean CO<sub>2</sub> uptake might be underestimated, since rain will lower surface ocean pCO<sub>2</sub> in both source and sink regions and, hence, increase uptake in sink regions and decrease outgassing in source regions.","AbstractOtherLang":null,"BibLvlCode":"AS","StandardTitle":"Precipitation‐induced reduction in surface ocean pCO<sub>2</sub>: Observations from the eastern tropical Pacific Ocean","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2026-05-10 01:32:50.896973","timezone_type":1,"timezone":"+02:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":2020,"MonPub":null,"DateUpdate":"2020-09-04","DateCreate":"2020-08-25","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":"WOS:000560376100112","VABBcode":null,"OpenAcc":0,"DOI":"10.1029/2020gl088252"},"refs":null,"anarec":{"AnaID":328247,"PubliDate":2020,"Pagination":"e2020GL088252","XtraPublOfAnaID":null,"ISBN":null,"Volume":"47","Issue":"15","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":42920,"SerRR":"Geophysical Research Letters.
