“This wasn’t just any phytoplankton bloom,” says Kevin Arrigo, a Stanford University marine scientist and lead author of the study. “It was literally the most intense phytoplankton bloom I’ve ever seen in my 25 years of doing this type of research” in oceans around the world.

The scientists sampled only a relatively small section of ice above…
