Correction to: Nature Communications https://doi.org/10.1038/s41467-020-19956-7, published online 27 November 2020.

The original version of this Article contained an error in the Discussion, which incorrectly read ‘Assuming a krill population biomass of 379 Mt for the Southern Ocean, we estimate that the exuviae flux can contribute a seasonally averaged mean of 0.29 t C d−1 (SE 0.09; see Supplementary Methods).’ The correct version adds ‘M’ to the unit before ‘t C d-1’. The Supplementary Information file was also updated as one paragraph had many errors. These errors have been corrected in both the PDF and HTML versions of the Article.
