Our researchers @sotonoceanearth.bsky.social have examined 5 million year old plankton fossils as part of an international research project 🌊
The study suggests tropical Pacific Ocean ecosystems may be more resilient to climate warming than first feared.

Today, we published a study long in the making on how upper and subsurface tropical Pacific waters responded (and maybe will adjust) to warmer global climate. Here’s the story of how we got here after 15 years. many authors but shout out @jfarmersalmanac.bsky.social

Persistent eastern equatorial Pacific Ocean upwelling since the warm Pliocene
Upwelling generates a nutrient-rich “cold tongue” in the eastern equatorial Pacific Ocean (EEP), with impacts on global climate, oceanic biological productivity, and the carbon cycle. The cold tongue ...

Just published in Science! Our new study shows an oxygen increase in the tropical subsurface ocean during the PETM, reconstructed by foraminifera-bound nitrogen isotopes (FB-d15N) and a foraminiferal body size model (FS-pO2).

Oxygen rise in the tropical upper ocean during the Paleocene-Eocene Thermal Maximum
Oxygenation of the low-latitude tropical North Pacific Ocean increased during the Paleocene-Eocene Thermal Maximum despite high global temperatures.
