Tara Oceans expedition – 1/2 of oxygen on Earth
Planktonic life in the ocean is far more diverse than scientists knew, these reports show. They provide new resources for cataloguing the ocean’s numerous planktonic organisms, which — though critical to life on Earth, providing half the oxygen generated annually through photosynthesis, for example — have largely been uncharacterized. The reports also reveal how planktonic life is distributed and how planktonic species interact, and they suggest that these organisms’ interactions, more so than environmental conditions, help explain their community structures.
