What’s in an Isotope? Quite a Lot
A new technique developed by researchers at the Lamont-Doherty Earth Observatory now allows scientists to use an isotope of manganese not abundant on Earth to understand the record of millions of years of changes to the Earth’s surface. According to the study’s lead scientists, the new technique relies on measuring extremely small amounts of the…

Holey Asphalt: New Lamont Parking Lot will Help Reduce Runoff
It isn’t often that a new parking lot receives positive reviews from the environmental community. In keeping with Lamont Doherty Earth Observatory’s history of environmental stewardship along the Hudson River, however, the new lot currently under construction on campus is no ordinary blacktop. Intended as a replacement for the existing lot that will soon become…

Remembered: Marie Tharp, Pioneering Mapmaker of the Ocean Floor
Marie Tharp, a pathbreaking oceanographic cartographer at the Lamont-Doherty Earth Observatory, co-creator of the first global map of the ocean floor and co-discoverer of the central rift valley that runs through the Mid-Atlantic Ridge died Wednesday August 23 in Nyack Hospital. She was 86. A pioneer of modern oceanography, Tharp was the first to map…

Cosmic Dust in Ice Cores Sheds Light on Earth’s Past Climate
Each year nearly 40,000 tons of cosmic dust fall to Earth from outer space. Now, the first successful chronological study of extraterrestrial dust in Antarctic ice has shown that this amount has remained largely constant over the past 30,000 years, a finding that could help refine efforts to understand the timing and effects of changes…

Study Shows Lack of National Consensus on Teaching K-12 Students about Human-Environmental Impacts
The destruction caused by natural disasters such as Hurricane Katrina and human activities such as mountaintop removal mining are powerful examples of how the environment and society are tightly interwoven. But to what extent do, or should, state science curricula in the U.S. seek to investigate or influence the nature of this interaction? That is…
