🚨 Another new paper! 🚨

My coauthors and I gathered data on four planktic foraminiferal species from 115 core tops in the Indian Ocean to test the question: does adding non thermal parameters to Mg/Ca calibrations make them "better" than temperature-only models?

Check out our work below! 🌊🧪
Core-top constraints on the ecology and paleothermometry of planktic foraminifera in the Indian Ocean
The magnesium-to‑calcium ratio (Mg/Ca) of fossil foraminifera is a widely used geochemical proxy for reconstructing past ocean temperatures. Culturing…

🚨 New Paper Alert! 🚨

We reconstructed past ocean salinity in one of the largest Subantarctic Mode Water production centers on the planet: the southeast Indian Ocean. We found a rapid increase in SAMW salinity during the Last Deglaciation.

Where did this salt come from? We argue the deep ocean. 🧪🌊
Elevated shallow water salinity in the deglacial Indian Ocean was sourced from the deep - Nature Geoscience
Increased salinity of Subantarctic Mode Water during the initial phase of the Last Deglaciation could have enhanced deep water formation in the North Atlantic, according to proxy records from a sedime...
