April 28, 2022 ・ Liana Wait

As greenhouse gas emissions continue to warm the world’s oceans, marine biodiversity could be on track to plummet within the next few centuries to levels not seen since the extinction of the dinosaurs, according to a recent study in the…

What caused the ice ages? Tiny ocean fossils offer key evidence

December 10, 2020 ・ Liz Fuller-Wright

The last million years of Earth history have been characterized by frequent “glacial-interglacial cycles,” large swings in climate that are linked to the growing and shrinking of massive, continent-spanning ice sheets. These cycles are triggered by subtle oscillations in Earth’s…

Geyman’s published senior thesis research offers new thoughts on how carbonates record global carbon cycle

November 8, 2019 ・ Tom Garlinghouse
