Productivity varies across the area, with notably high planktonic diversity and abundance associated with oceanic fronts (e.g. the Subpolar Front) and topographic features (e.g. the Charlie–Gibbs Fracture Zone; see the “Key signals within the environment and the ecosystem" section).
There are no time-series of data for zooplankton and micronekton of the meso- and bathypelagic zones, i.e. deep-living components that are highly significant in the foodwebs of ridges, seamounts, abyssal plains, and continental slopes of this ecoregion.
