Figure 12.

Quartile diagrams of (a) MLD, (b) [Chla]_sat, (c) mean daily PAR in the mixed layer (${\overline{iPAR}}_{ML}$), and (d) mean nitrate concentration in the ML (${\overline{Nitrate}}_{ML}$) per Northern Hemisphere‐phased month (regardless of the year) for GHOZ profiles with a monthly occurrence of DCM profiles (color gradient). The North Atlantic Current is excluded from this representation, as not being part of the Southern Ocean sub‐regions on which our analysis essentially focuses. DCM, Deep Chlorophyll Maximum; GHOZ, Ghost Zone; MLD, Mixed Layer Depth; PAR, Photosynthetically Available Radiation.
