Strontium to calcium ratio and oxygen isotopic coral records can exaggerate past decadal tropical climate variability - Communications Earth & Environment Strontium to calcium ratio and oxygen isotopic records from single corals contain a strongly autocorrelated non-climate noise component, which can inflate reconstructed temperature variability, according to analyses of coral records and sea surface temperature data.

New research by #SPP2299 researcher Andrew Dolman in @commsearth.nature.com on signal and noise in coral records

The PAGES CoralHydro2k Seawater δ18O Database: a FAIR-aligned compilation of seawater δ18O data to uncover “hidden” insights from the global ocean Abstract. The stable isotope values of seawater (δ18O and δ2H) provide valuable information on the exchange of water between the ocean, atmosphere, and cryosphere and on ocean mixing processes. As suc...

Equatorial upwelling of phosphorus drives Atlantic N2 fixation and Sargassum blooms - Nature Geoscience High near-surface nitrogen-fixation rates that promoted the recent growth of the Great Atlantic Sargassum Belt were tied to greater upwelling of phosphorus from the equatorial Atlantic, according to c...

Check out our latest work, led by Jon Jung, Ph.D. student in the @amglab.bsky.social at @mpic.de:

www.nature.com/articles/s41...

Here we show that the supply of excess phosphorous from accounts for the majority of observed Sargassum variability since 2011.

The driver of Sargassum blooms in the Atlantic Ocean

The driver of Sargassum blooms in the Atlantic Ocean:
Upwelling of phosphorus-rich deep water promotes an N-fixing symbiont of the Sargassum algae giving it a competitive advantage.

Thanks to everyone who joined our Meeting & Status Seminar 2025 - It was such a mix of minds and experiences. It was not just about presentations - It was about connecting ideas, perspectives, and people. Events like this remind us why we do research: To explore, to question, and to grow - Together
