On every continent and ocean, Lamont-Doherty Earth Observatory field researchers are studying the dynamics of climate, geology, natural hazards and ecology. Explore where they're headed and what they hope to learn.
Humans have been burning fossil fuels for only about 150 years, yet that has started a cascade of profound changes that at their current pace will still be felt 10,000 years from now. Adjunct Senior Research Scientist Anders Levermann describes the changes being set in motion now.
When you examine the behavior of the global oceans closely – really closely, at scales smaller than 100 kilometers – eddies and jets and fronts start to appear. For Lamont's Ryan Abernathey, who was just awarded a 2016 Sloan Research Fellowship, this is where ocean physics gets interesting.
Scientists plumbing the depths of the central equatorial Pacific Ocean have found ancient sediments suggesting that one proposed way to mitigate climate warming—fertilizing the oceans with iron to produce more carbon-eating algae—might not necessarily work as envisioned. Lamont doctoral student Kassandra Costa explains what her team found.
Deep beneath Alaska’s Aleutian Islands, down where the pressure and temperatures have become so high that rock starts to flow, new continental crust is being born. Scientists have long believed continental crust forms in volcanic arcs. The lingering question has been how exactly that happens. Lamont's Peter Kelemen puts a new theory to the test.
Your support can revolutionize Earth science research and education
Lamont-Doherty Earth Observatory seeks fundamental knowledge about the origin, evolution and future of the natural world. Our scientists study the planet from its deepest interior to the outer reaches of its atmosphere, on every continent and in every ocean, providing a rational basis for the difficult choices facing humanity.
