From poetry to music to movies, we’re always hearing about the “deep blue sea.” But the seas aren’t always deep blue. And sometimes, they’re not blue at all. They can be green, brown, or other colors. And each color can tell us something about what’s happening in that part of the sea.

Understanding what the colors are telling us is one goal of PACE—Plankton, Aerosol, Cloud, Ocean Ecosystem—a NASA satellite that launched in February.

During bicycling races, cyclists often ride close together to take advantage of drafting, where a low-pressure area created behind a cyclist gives a boost to the one following them so the whole group can expend less energy. While the dynamics of ocean currents underwater are a bit different from air currents, it turns out that a similar strategy can help fish in turbulent water. New research has revealed that fish can swim far more easily, and use much less energy, swimming together in a school than battling the currents on their own.
