Figure 7.

EOF-reconstructed Chl composites during different climate variability regimes. Chl values are reconstructed using the first 5, 6 and 5 dominant modes for Carlini Station (PC), Palmer Station and Rothera Station, respectively. (a) Spring (October–November–December or OND) Chl composites and (b) winter (July–August–September or JAS) Chl composites when preceded by El Niño/−SAM and La Niña/+SAM conditions in July. Owing to small sample sizes (n = 9 and 15 for El Niño/−SAM and La Niña/+SAM) in the analyses, a relaxed criterion was used for the level of significance at p < 0.10. (Online version in colour.)
