Distilling Art from the Figures of Science
Any researcher can attest to the fact that a scientific figure is worth more than a thousand words. Rarely do we take a step back to consider the inherent artistry in the figures created to convey the science.

Study Reveals Microbes’ Hidden Role in Fertilizing Oceans
Surprisingly little has been known about how phosphorous, an essential nutrient, cycles through the oceans. A new study has broken through some of this mystery, by showing the hidden role that the oceans’ tiniest creatures play.

Bad Ozone Days in Western U.S. Linked to Pacific Weather
A new study shows that ozone pollution in the western United States can be increased by La Niña, a natural weather cycle at the surface of the Pacific Ocean. The finding is the first to show that the La Nina-El Nino cycles directly affects pollution.

Smooth Sailing Back to Tasmania
After a surprisingly smooth crossing of the Southern Ocean, with favorable winds we arrived back in Hobart, Tasmania. The weather maps show that we just got ahead of another big storm system.

Taking a 4,000-Meter-Deep Profile of Antarctic Waters
In addition to understanding potential pathways for “warmer” circumpolar deep water to reach the ice shelf, we are also measuring what the structure and properties of the water column are and determining if there is already warmer water on or near the continental shelf that could already interact with the glaciers of East Antarctica today.

Lamont-Doherty to Manage U.S. Ocean Drilling Program
Columbia University’s Lamont-Doherty Earth Observatory has signed a $35 million, five-year cooperative agreement with the U.S. National Science Foundation to manage scientific support services for U.S. scientists studying the world’s ocean floors.

Mapping the Seafloor
One of the goals of this expedition is to investigate if water from the Southern Ocean with temperatures above the melting point of glaciers could reach the glaciers in East Antarctica, and if there are any obstacles on the seafloor of the shelf that impact the ability of such water to reach the glaciers and…

In a Melting Iceland, Drilling Deep to Stem Climate Change
Iceland is pioneering a new technology to deal with climate change. Its Hellisheidi geothermal power plant, the world’s largest, hosts arguably the world’s most advanced program to capture and lock away globe-warming carbon dioxide.
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
