Maureen E. Raymo Appointed Interim Director of Lamont-Doherty Earth Observatory

Lamont’s seagoing geophysicist Walter C. Pitman III helped revolutionize the Earth sciences.

Lamont scientists have discovered previously unrecognized structural lines 100 miles or more down in the Earth that appear to signal the locations of giant deposits of copper, lead, zinc and other vital metals. 

COVID-19 has created a set of climate consequences and benefits. Pandemic-related lockdowns have also impacted Lamont research.

Lamont polar scientist Marco Tedesco writes about how the environmental tragedy of deforestation and fires destroying huge expanses of the Amazon rainforest continues and worsens even in the face of the pandemic.

A group of students—working under the direction of Lamont geochemist Benjamin Bostick—examined the types of microplastics entering the river, and created a way for citizen scientists to help with the research.

Women and people of color are historically underrepresented in the geosciences. Through two different diversity initiatives, graduate student Kailani Acosta is working to change that.

Lamont oceanographer Pierre Dutrieux uses new data and methods to examine the thinning and melting of the massive West Antarctic Ice Sheet. His research will help enable the scientific community to better project the future stability of the ice sheet and associated sea level rise.

A simple fascination with winter and weather patterns led Lamont paleoclimatologist Rosanne D’Arrigo to become a globe-trotting scientist who collects and analyzes important data from tree rings.

Lamont’s Suzana Camargo—who explores and defines risks to people, property, and the economy in the face of escalating extreme weather events—weighs in on this year’s daunting hurricane forecast.

A new study led by Lamont climate scientist Galen Mckinley finds that ocean absorption of CO2 rises and falls along with human activity and natural phenomena. The findings are important for understanding how much the oceans will offset future climate change.
