UnDisciplined: What can marine microorganisms tell us about the ocean?

The ocean takes up roughly 70% of the planet, but we still don’t know too much about everything that is out there. Most ocean life is very small, and tends to change based on the ocean’s conditions. So even if you took a sample of ocean water right now, there’s really no guarantee that it would resemble a sample taken later.A recent study by Sarah Tucker and her team offers some direction for filling in that gap.
