English: Export Processes in the Ocean from Remote Sensing. The EXPORTS conceptual diagram illustrates the links among the ocean's biological pump and pelagic food web and our ability to sample these components from ships, satellites, and autonomous vehicles. Light blue waters are the euphotic zone (EZ), while the darker blue waters represent the twilight zone (TZ). Figure is adapted from Steinberg (in prep.) and the U.S. Joint Global Ocean Flux Study (JGOFS) (http://usjgofs.whoi.edu/images/biological_pump.tif).
