@alexauderset.bsky.social shows the size of foramnifera using a matchstick for scale #geochemistry

GGRiP Bristol has begun! @alexauderset.bsky.social gave a fantastic keynote on nitrogen isotopes as a tool in paleoceanography!

🚨New paper out with @alexauderset.bsky.social! We show that the Arabian Sea oxygen minimum zone (OMZ) was better oxygenated during the warm Miocene Climate Optimum than today, but its path to full deoxygenation was slow and complex. Link to paper: www.nature.com/articles/s43...

Contrasting evolution of the Arabian Sea and Pacific Ocean oxygen minimum zones during the Miocene - Communications Earth & Environment

The Arabian Sea and eastern tropical Pacific oxygen minimum zones were better oxygenated during the warm Miocene, but with regional complexities, according to analysis of trace elements and nitro...

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. Find out more 👉 tr.ee/BpAlpo

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 🌊 www.science.org/doi/10.1126/...

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 ...

Packed room at EGU for @alexauderset.bsky.social talk on ocean deoxygenation in past warm climates!

If you plan to go to Goldschmidt this year, please consider submitting an abstract to our Session 13g! Keynote speaker: Sze Ling Ho (National Taiwan University) Deadline approaching fast: 29th of March conf.goldschmidt.info/goldschmidt/...

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). Check out the paper: www.science.org/doi/epdf/10....
