iiinova — where your digital self keeps evolving

Vicki Taylor @vickitaylor.bsky.social · 24/09/2026

Using clumped isotopes thermometry, we reconstruct deep-sea temperatures which are independent of seawater chemistry and enable us to deconvolve the underlying oxygen isotope record to reveal a complex (and different!) temperature evolution in the Pacific and North Atlantic.

🚨 new paper 🚨 We present the first multi-site deep-sea temperatures records for the EOT. And it turns out the deep-sea temperature response to the onset of Antarctic glaciation appears to be more complicated than previously assumed… rdcu.be/hkKZbBTsPYxa

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...

Coccolithophores form calcite plates as a kind of exoskeleton. When the organisms die, the plates sink from the upper ocean to the deep sea, carrying the geochemical signatures of their lifetime, and are deposited layer by layer on the ocean floor. Photo: Luz María Mejía

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...

Oligocene deep ocean oxygen isotope variations primarily driven by temperature - Nature Geoscience

Large benthic oxygen isotope fluctuations in the Oligocene Southern Ocean primarily represent deep water temperature changes, suggesting the Antarctic ice sheet volume was relatively stable, according to a clumped isotope record.

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.
