Fig. 2: Contribution of major phytoplankton groups to total Chl a with depth.
From: Small phytoplankton contribute greatly to CO2-fixation after the diatom bloom in the Southern Ocean
Total Chl a concentrations correspond to the cumulative concentration of taxon-specific Chl a. The panels are organized here according to the rate of decrease of small phytoplankton pigments. The black line indicates Phaeopigment:Chl a ratio. Phaeopigments correspond to degraded and Chl a to fresh pigment material. The dashed black line corresponds to a ratio of 1. a Stations have Phaeo/Chl a ratio above 1 at 200 m depth, whereas b stations the ratio is <1.
