Ocean algae blooms earlier, with potential ripple effects to come

Warmer oceans are acting like a catalyst for one of the world's most abundant species of plankton, triggering earlier blooms of blue-green algae in the waters of the North Atlantic. Because of plankton's fundamental role in the marine ecosystem, researchers expect this shift to have far-reaching impacts throughout the world's oceans. The study, published in the journal Science, focused on Synechococcus, a type of blue-green algae that is one of the most abundant phytoplankton in the ocean. The authors drew on 13 years worth of data to measure the spring blooms that cover the North Atlantic in a carpet of green each year.
