Fig. A1. An image of a table taken from Krafft et al. (2010), displaying the outcome of a cluster analysis of krill trawl stations and the environmental parameters at each station. Only trawl stations in clusters 2B1 and 2B2 contained krill, which were all located south of the polar front in the vicinity of Bouvetøya. Krill in cluster 2B1 comprised lower proportions of juveniles and higher proportions of adult males and females compared to cluster 2B2. The temperature and SWPDA (Sigma-t, mg/m3) values attributed to these clusters (highlighted in red) are closely matched with the values derived from the distribution analysis of penguin maximum dive depths, SWPDA and temperatures identified in Fig 2 of this study. The water conditions within these clusters are similar to those in which penguins conducted longer-than-expected dives (see Fig 3 in text).
