Exploring the Bering Sea Ecosystem
Our stations have continued to be rich in phytoplankton, while our colleagues are excited by the larval fish they are finding in the southern Bering Sea. Wildlife sightings have included whales, dolphin, and the jawless lamprey fish, and we are settling in for potentially bumpy seas ahead.

Switchyard 2012: Climate Change in the Arctic
Arctic summer sea ice is declining rapidly: a trend with enormous implications for global weather and climate. Now in its eighth year, the multi-year Arctic Switchyard project is tracking the Arctic seascape to distinguish the effects of natural climate variability from human-induced climate change. The University of Washington is leading the project. A) The Canadian…

The Double-Edged Sword of Geoengineering
Shooting sulfur particles into the stratosphere to reflect the sun? Dumping iron into the ocean to boost the absorption of carbon dioxide? Could these far-fetched and dangerous-sounding schemes—geoengineering—help avert potentially catastrophic effects of climate change, or would they exacerbate conditions on our ever warming planet?

Diatoms and Dessert
The lovely spring weather in New York City as I prepared for this cruise was difficult to leave behind, and it will be nearly summer once we return. In the Bering Sea, it still feels like winter. For the past two days we have sampled water out on deck with snowflakes falling from the sky.
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
