The introduction of chlorophyll maps from satellites provided a view of the often-complex interactions between phytoplankton and physics in the surface ocean. The large panel (A) provides an example of this complexity for coastal California, depicting ocean chlorophyll concentrations from the Sea-viewing Wide Field-of-view Sensor with some typical physical features annotated. The Inset (B) is an adaptation of the Mandala of Margalef (17), who attempted to map phytoplankton functional types into physicochemical environmental space. Blue functional types were included in the original conceptual diagram. As noted by others (18), the Mandala breaks down for many phytoplankton functional types because the physicochemical control is often more complicated than two factors (i.e., dimensions) can portray. d'Ovidio et al. (1) provide a method for mapping these functional types geospatially using a combination of ocean color and satellite altimetry. This may ultimately allow researchers to move beyond simple chlorophyll maps (A) by tracking fluid dynamical niches that integrate the biological response of groups of phytoplankton to their environment, thereby capturing the multidimensional forcing shaping the ocean landscape.
