    Studying Bioluminescent Blooms in the Arabian Sea

    A plankton-like species is attacking the base of the food chain in the Arabian sea, disrupting water quality and killing fish. Researchers at the Lamont-Doherty Earth Observatory are learning how to fight back.

    Rapid-Fire Cyclones over the North Indian Ocean

    With Chapala’s destructive landfall in Yemen just a couple of days in the past, a second tropical cyclone, Megh, has just formed in the Arabian Sea. This one is not forecast to become anywhere near as intense as Chapala did—though we know intensity forecasts can be wrong, as they were at early stages for both…

    An Algorithm to Investigate Unwelcome Plankton

    Computer scientists at Columbia University will work with oceanographers to understand what has caused an unusual plankton-like species to rapidly invade the Arabian Sea food chain, threatening fisheries that sustain more than 100 million people.

AGU25, the premier Earth and space science conference, takes place December 15-19, 2025 in New Orleans, Louisiana. This year’s theme—Where Science Connects Us—puts in focus how science depends on connection, from the lab to the field to the ballot box. Once again, Lamont-Doherty Earth Observatory and Columbia Climate School scientists, experts, students, and educators are playing an active role, sharing our research and helping shape the future of our planet. #AGU25 Learn More
