Research In Lake Superior Reveals How Sulfur Might Have Cycled In Earth’s Ancient Oceans

by Keith CowingNovember 17, 2023November 17, 2023

Geochemist Alexandra Phillips has sulfur on her mind. The yellow element is a vital macronutrient, and she’s trying to understand how it cycles through the environment. Specifically, she’s curious about […]
