The U.S. had seven operating offshore wind turbines with 42 megawatts of capacity in 2021. The Biden administration’s goal is 30,000 megawatts by 2030. AP Photo/Michael Dwyer

Offshore wind farms could help capture carbon from air and store it long-term – using energy that would otherwise go to waste

Wind turbines often can produce more power than is needed for electricity onshore. That extra energy could be put to work capturing and storing carbon.

Marie Tharp pioneered mapping the bottom of the ocean 6 decades ago – scientists are still learning about Earth’s last frontier

Born on July 30, 1920, geologist and cartographer Tharp changed scientific thinking about what lay at the bottom of the ocean – not a featureless flat, but rugged and varied terrain.

Scientist at work: I’m a geologist who’s dived dozens of times to explore submarine volcanoes

When you study volcanoes at mid-ocean ridges, doing fieldwork means becoming an aquanaut – diving thousands of feet to the ocean floor in the submersible Alvin, trading tight quarters for amazing views.
