Five Questions with Uta Passow, How An Oil Spill Affects the Movement of Carbon In the Ocean

There are millions of tiny drifting plants in the sunlit ocean, called phytoplankton. They produce oxygen that humans end up breathing in and provide food for animals in the plankton (the zooplankton). After death,...

Sea Level Rise

The ocean never stops moving. When you visit the beach, waves roll in and recede and the tides rise and fall. These are small daily changes that balance out over time. But over the...
