Reconstructed 10 °C upper ocean meridional temperature gradient during the early Eocene but significant proxy-model differences, especially in the Southern Ocean, persist.

A new view on past climate in the North Atlantic 🌊 MARUM-study uses clumped‑isotope geochemistry on ultra‑pure fossil phytoplankton to reconstruct 16 million years of ocean temperatures. Read more here ➡️ www.marum.de/en/clumped-i...

❄️ Marked by the onset of large scale Antarctica glaciation, the EOT marks a key pivot point in Cenozoic climate history towards the development of the modern climate system. ❄️ Don’t miss our EGU session on ‘Decoding the Eocene–Oligocene Transition’ in the marine and terrestrial realm.

☀️❄️🌡️ From hot to cold: Advances in reconstructing and modelling Cenozoic ocean and terrestrial temperatures ☀️❄️🌡️ Don’t miss our EGU session focussing on robust reconstructions of past temperatures and new approaches for addressing the challenges associated with past temperature reconstructions.

🚨 New vacancy🚨 Interested in high-resolution climate reconstructions, or know someone who might be? Apply for our exciting new, fully funded PhD position where you will develop reconstructions of extreme weather events in the geological past from fossil shells! 🌩️🌀🌊🐚 werkenbij.vu.nl/vacatures/ph...

For the first time, scientist discovered that the large up-and-downs in oxygen isotopes of the mid Oligocene were primarily driven by large temperature changes in the abyssal ocean and not, as previously assumed, to enormous changes in ice volume in Antarctica. 3/3 www.nature.com/articles/s41...

Paper Alert❗️We present the first Oligocene record of orbital variability in abyssal ocean temperature based on benthic foraminiferal clumped isotopes. Temperature changes up to 4 degrees C with a 110 kyr pacing, indicating Antarctic ice-volume at this time was less dynamic than previously thought.

By measuring the proportion of the heavy oxygen isotope in deep ocean marine calcite, scientist can understand climate variability in the geological past. This is measured on the fossil shells of microscopic organisms that have lived on the ocean floor for hundreds of millions of years ago. 🧪🌊 1/3

Interested in improving our knowledge of climate by looking into the past? In the Pliocene the earth was hotter than today, but carbon dioxide was "about the same". Come work with us in 2026 looking at where this crucial information comes from, and how to make it better during an M2 internship.

Recalibrating the past 100 million years on a unified, accurate and precise timescale? 🕰️ That is the aim of the ambitious TIMES project. Read more about the Kick-Off meeting here ➡️ www.marum.de/en/Kick-off-...

New paper! Check out @zifeiyang.bsky.social gorgeous data from M2 glaciation (3.3Ma) - stunning Melonis Mg/Ca temperature records allow us to be confident about ice growth, but this was not like later glaciations following iNHG, we think gateways were more important: www.nature.com/articles/s41...

🚨Job alert PhD 🚨 We are looking for 15 new doctoral researchers at @marumunibremen.bsky.social @unibremen.bsky.social. Don't miss this fantastic opportunity! The deadline is the 25th of July. More information about the projects and how to apply can be found here 👇 www.uni-bremen.de/en/universit...

Our researchers have conducted a groundbreaking analysis of prehistoric plankton 🔬 They have revealed how these microscopic organisms adapted to their environment not just across generations, but on a day-to-day basis. Find out more 👉 tr.ee/1ESp0h @sotonoceanearth.bsky.social @noc.ac.uk

The Pacific Highs remain an under-explored treasure trove of information on past warm climates. Coordinated international efforts are the framework within which these archives can be best explored to address urgent and societally relevant questions regarding future climate change scenarios.
