Short summary
Chlorophyll a (Chl a), which is the primary pigment used in photosynthesis, often retains its maximum value in the subsurface layer rather that at the surface. In this study, we integrate Chl a concentration data from recent biogeochemical floats, as well as from historical ship-based and other observations, and present global maps of subsurface Chl a concentration and seasonal and interannual variations with related variables, i.e., light intensity, nitrate concentration, and oxygen production.
