🌊In a new study co-led by USF professor @oceanandclimate.bsky.social Patrick Rafter, researchers used forams from the Pliocene to show that warming in the tropical Pacific may not trigger the severe decline in nutrients predicted by earlier models.

How ancient plankton point to the resilience of ocean ecosystems
The researchers used a cutting-edge approach to predict future ocean conditions by examining the distant past through analyses of microscopic fossils.
