Correction: Concentrations and properties of ice nucleating substances in exudates from Antarctic sea-ice diatoms

Abstract

Correction for ‘Concentrations and properties of ice nucleating substances in exudates from Antarctic sea-ice diatoms’ by Yu Xi et al., Environ. Sci.: Processes Impacts, 2021, 23, 323–334, DOI: 10.1039/D0EM00398K.

In Fig. 4 of the original paper, the wrong data was plotted for Skeletonema marinoi. Mistakenly, the authors plotted the number of INS per mass of DOC instead of the number of INS per mass of total material for Skeletonema marinoi. The correct Fig. 4 is shown below. The conclusion reached from the comparison of INS concentrations of different diatom samples in the original paper was that the ice nucleating abilities of sea-ice diatom and temperate diatom samples were similar. The correct Fig. 4 provides stronger support for this conclusion. Some of the references in the original caption were incorrect and the new, correct references have now been added in the caption below.

Fig. 4 Number of INSs per mass of total material, n_m,total, for the Nitzschia supernatant sample and cultured sea ice diatom and temperate diatom samples from Ickes et al.¹ For the cultured samples, the total mass of material in the cultures was estimated using their reported number of cells¹ and assuming a cell density of 1 g cm⁻³ and cell volume of 653 and 125 μm³ for Melosira arctica and Skeletonema marinoi respectively.² The error bars were calculated based on 95% confidence intervals from the nucleation statistics.³ Also included for comparison are INSs per mass of material for other atmospherically relevant INSs.^1,4–8

The Royal Society of Chemistry apologises for these errors and any consequent inconvenience to authors and readers.
