In the article “Oxygen isotopic evidence for accretion of Earth’s water before a high-energy Moon-forming giant impact,” in the first paragraph of the Results section, the final term in the definition of Δ17O was corrected from “+ γ” to “– γ”. In paragraph 5 of the Discussion section, the CI value, originally published as −1.03, was corrected to −0.24. The relevant sentence now correctly reads, “Compared to terrestrial samples, which have an average ɛ100 Ru value of +0.05, CIs have a value of −0.24 and ordinary chondrites have an average value of −0.29 (31).” The HTML and PDF versions of the paper have been corrected.
