Planktonic foraminifera Iodine/Calcium ratio: is it a proxy for dissolved oxygen in the ocean?
Abstract. Direct observations indicate a declining trend in ocean oxygen concentrations, which is not quantitatively captured by models. The complexity of oxygenation variability, linked to both physi...

Four days later, I think I can finally process this:

I’ve been awarded a Marie Skłodowska-Curie Postdoctoral Fellowship (#MSCA -PF 2025).

17,066 applications this year. ~9.6% funded.

Still feels slightly unreal.

CO2-driven warming during the Pliocene can be used as an analog for present-day warming. A temperature record from a Colombian sedimentary core suggests that the tropics were 4.8 °C warmer in the Pliocene than during the late Pleistocene. In PNAS: https://ow.ly/iJ1c50YbG8B

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.
