Corrigenda to: Standing stock of Antarctic krill (Euphausia superba Dana, 1850) (Euphausiacea) in the Southwest Atlantic sector of the Southern Ocean, 2018–19

Summary

This correction document fixes an error in the original publication of the major 2018-19 Antarctic krill population survey in the Southwest Atlantic region. The correction specifically updates Figure 3, which contained incorrect data in the original research paper. The corrected figure shows three separate charts (labeled SS, AP, and Sand) that display the size distribution of krill populations, with krill lengths measured from 0 to 60 millimeters and population proportions ranging from 0 to 8%. This technical correction ensures the published data accurately represents findings from this significant international survey, which estimated 62.6 million tonnes of krill biomass across the Southwest Atlantic sector. The correction preserves the scientific reliability of this crucial baseline study used for Antarctic krill population assessment and fisheries management.

These details have been updated only in this correction document to maintain the accuracy of the official published record.

Key Findings

Figure 3 was corrected to accurately show krill size distributions across three different categories (SS, AP, Sand).

Krill length measurements covered the 0-60 millimeter range, which is typical for Antarctic krill populations.

The size distribution data shows most krill were concentrated in the 20-40 millimeter length range.

This technical correction ensures the accuracy of data from the major international krill population survey.

The correction maintains the scientific reliability of the 62.6 million tonne krill biomass estimate from the 2018-19 survey.

Accurate krill size distribution data is essential for proper interpretation of population structure in fisheries management decisions.

Abstract

In the originally published version of this manuscript, an incorrect figure was submitted as Figure 3. The correct figure is included below. These details have been corrected only in this corrigenda to preserve the published version of record.
