[18-May-18] This illustration links the ocean biological pump and pelagic food web. Campaigns such as EXPORTS will utilize ships, satellites and autonomous vehicles to sample many parts of this system. The gradient between the light blue and dark blue waters represents the boundary between the euphotic zone (where most primary production occurs) and the twilight zone (where sinking occurs).
