Author Correction: Economic and biophysical limits to seaweed farming for climate change mitigation

Correction to: Nature Plants 10.1038/s41477-022-01305-9. Published online 23 December 2022.

In the version of this article initially published, in the Results subsection “Costs and benefits of large-scale seaweed farming”, the percentages of ocean area farmed to reach 1 Gt and 3 Gt of CO₂ sequestered by sinking seaweed in the ambient nutrient scenario were incorrect due to typographical errors. As a result, in the sentence beginning “In the optimistic case”, “0.85%” is now “0.110%”, “310,000 km²” is now “400,000 km²”, and “Poland” now reads as “Zimbabwe”. In the sentence following, “is slightly higher: 0.036% and 0.099%” now reads as “is 0.035% and 0.100%” and “$40” is now “$30”. Furthermore, in the penultimate sentence of this paragraph, “ocean areas of 0.09–0.10% and 0.28–0.37%” now reads as “ocean areas of 0.085–0.100% and 0.285–0.410%” and “roughly 320,000–360,000 km² and 1,010,000–1,330,000 km²” is now “roughly 310,000–360,000 km² and 1,030,000–1,480,000 km²”. Calculated values in this subsection have been revised to reflect these corrections: in the sentence beginning “Average costs at the median of Monte Carlo”, “$1,110–$2,100” is now “$1,120–$2,090”; and in the paragraph beginning “Despite being a small percentage”, “17%” is now “18%” and “61%” is now “64%”. Corresponding values in the Methods subsection “Comparison of gigaton-scale sequestration area to previous estimates” and in Supplementary Figures 10 and 11 have been updated accordingly. The errors have been corrected in the HTML and PDF versions of the article.
