The Ocean Is Changing Color

The ocean is getting greener — and bluer. Scientists can see it from space. But what does it mean?

In this episode of Shoresides, host Nicolas Magrino speaks with Philip Bresnahan, associate professor at the University of North Carolina Wilmington, about what’s driving subtle but measurable changes in ocean color around the world. From warming waters to shifting nutrient flows, the hues of the sea are telling a complex story — one that hints at the far-reaching effects of climate change, but also at the deep, dynamic rhythms of the ocean itself.
