Fig. 3: Global patterns and trends in phytoplankton absorption coefficients, carbon biomass, and growth rates.
From: Global declines in net primary production in the ocean color era

Average a phytoplankton absorption coefficient (aϕ), b phytoplankton biomass integrated over the euphotic zone (Cphyto), and c phytoplankton growth rates (μ), d–f) corresponding decadal trends normalized to their respective mean (1998–2022), where hatching denotes regions where the trend exceeds the 90% confidence interval.
