Our team spent most of Friday on the Arctic sea ice, drilling and sampling ice cores at our main field site. For each core collected, Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack take a number of different physical, chemical and biological measurements
On Thursday we lowered a camera into an ice borehole to get a look at the underside of the ice. In the following video, you can clearly see the algae living in the bottom of the ice due to their pigments, which they use to harvest light.
The Earth Institute is pleased to welcome National Grid into the Corporate Circle, a collective partnership of leading corporations from across the globe committed to pursuing sustainable development objectives. Through a generous gift, National Grid will support sustainable energy research at the Earth Institute.
Fieldwork is exciting and inspiring, leading scientists to new ideas, places and observations about how the world works. Spring on Alaska’s North Slope provides an especially productive environment for fieldwork. When the sun never sets, it’s easy to linger in the field and the lab long into the well-lit night.
While I arrived in Barrow, Alaska on Tuesday, Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack, and graduate student Kyle Kinzler from Arizona State University, got here one week ago.
Of non-Arctic states, China has shown the most interest in the Arctic as climate change opens up the region to new economic development. The ways in which China attempts to balance its economic interests and environmental responsibilities within its energy policy may provide a predictor of its future behavior in the Arctic.
Andy Juhl and Craig Aumack, microbiologists from Columbia University’s Lamont-Doherty Earth Observatory, are spending a month in Barrow, Alaska studying algae in and below sea ice, and how our warming climate may impact these important organisms.
Some 800 years ago, ancestors of modern Mongolians conquered the world on horseback. Researchers are investigating whether a spell of unusually mild weather helped propel them by making them rich in livestock.
Eight hundred years ago, relatively small armies of mounted warriors suddenly exploded outward from the cold, arid high-elevation grasslands of Mongolia and reshaped world geography, culture and history in ways that still resound today. How did they do it?
New research gives a unifying explanation of the Sahel’s past, present and future climate patterns.
