Neodymium isotopes: what they actually tell us about ocean circulation (in the past) and the annoying issues with how they're affected by diagenesis. 🧪🌊

Fossil foraminifera indicate tropical Atlantic nitrogen fixation was lower in the warm late Pliocene. Pacific denitrification also weakened, potentially limiting the phosphorus that fuels fixation. doi.org/hcjr6b

🧬 Ancient ocean nitrogen cycle shifted with warming Fossil records show nitrogen-fixing activity in the tropical Atlantic dropped during a warm period 3m years ago, then rebounded as the climate cooled. 🔗 doi.org/10.1038/s41467-026-75846-4 #OceanScience #Climate #Paleoclimate 🧪

It’s been a spectacular few days in the Southern Great Barrier Reef on the RVInvestigator. Getting lots of great oceanography data and sea floor mapping, along with more sediment cores to understand the past, present and with improved models… the future. 🌊🪸🐋

Excited to share a new publication led by @maayanyehudai.bsky.social, "Reduced N2 fixation in the tropical Atlantic Ocean during the warm late Pliocene," out in Nature Communications today! Open access: www.nature.com/articles/s41... (1/~8)
