It has been brought to our attention that two articles published in Journal of Fluid Mechanics were assigned the same Digital Object Identifier (DOI). As a result of this, if readers attempted to use the DOI to resolve to the article, they would have reached only one (Guardone et al. Reference Guardone, Colonna, Casati and Rinaldi2014). We have corrected this error by assigning a new unique DOI to Weinstock (Reference Weinstock2013), namely https://doi.org/10.1017/jfm.2014.13. This has been corrected in the original, a footnote added to explain the circumstances, and the record in CrossRef updated.
We apologise to the authors of the two articles, and to readers who have been affected in their navigation to the respective articles.
