Fig. 5: Reproducibility of the annual seasonal cycle of chl-a (SCR, in %) as an indicator of interannual variability between 1998 and 2022 (based in Thomalla et al., 2023).
From: Long-term satellite data reveals complex phytoplankton dynamics in the Ross Sea, Antarctica

The SCR varies between 0 and 40% (yearly cycles that are not very similar to the climatological cycle); 40–70% (yearly cycles that are somewhat similar to the climatological cycle) and 70–100% (yearly cycles that are similar to the climatological cycle). The phytoplankton growing season (September to April), during the period 1998–2022, was considered for this study.
