Exposure to airborne particulate matter (PM) has been shown to consistently correlate with pulmonary and cardiovascular disease.
The Center for River and Estuaries is an association of scientists from Columbia University that study various aspects of rivers and estuaries world wide including the distribution of sediments, th
A new study shows that fecal bacteria from sewage can persist in far greater quantities in near-shore sediments than in the water of the Hudson River.
Two solar array farms in Orange County, New York, will be completed at the end of November, poised to provide power to and reduce the carbon footprint of the Lamont Campus.
Plastic microbeads, common in soap, toothpaste and other consumer products, are flooding waters. A team from Lamont-Doherty Earth Observatory is doing the first large-scale assessment of their impact on New York’s waterways.
A new study analyzing storm intensity and impacts in the New York metro area aims to inform how communities can better prepare for winter storms and enhance resiliency as the effects of climate change exacerbate hazards.
A 500-foot rock face came crashing down from the Palisades cliffs along the Hudson River in Alpine, N.J. on Saturday night, shaking the ground for more than half a minute and dumping a fresh layer of boulders over a 100-yard strip of parkland below State Line Lookout. The shaking was strong enough to be registered by a seismic station a mile and a half away, at Columbia University’s Lamont-Doherty Earth Observatory, but no one was injured.
According to a new study, neighborhood differences in rates of childhood asthma may be explained by local levels of soot produced by trucks and residential oil burners. The study, by public-health and air-pollution scientists at Columbia University, appears
online in the Journal of Exposure Science and Environmental Epidemiology.
In the first statewide climate change outlook for New York, scientists say that the state may suffer disproportionate effects in coming decades compared with other regions, due to its geography and geology. The report paints a harsh picture, including possible extreme temperature and sea-level rises, downpours, droughts and floods. The changes are projected to affect nearly every region and facet of the economy by the 2080s, from ski resorts and dairy farms to New York City’s subways, streets and businesses.
People are swimming in the Hudson again, and while clumps of sewage rarely float by anymore, the water is not reliably clean, says a report released this week from the environmental group Riverkeeper.
New York subway commuters may worry more about rats and rising fares than dust floating through the system, but for the workers who spend their whole shift below ground, air quality has long been a concern. Results from a new pilot study using miniaturized air samplers to look at steel dust exposure may help them breathe easier.
Scientists say buried volcanic rocks along the heavily populated coasts of New York, New Jersey and New England, as well as further south, might be ideal reservoirs to lock away carbon dioxide emitted by power plants and other industrial sources.
That rumbling you feel is not necessarily a passing subway. New York City and the surrounding region gets a surprising number of small earthquakes, and a 2008 study from the region’s network of seismographs, run by Lamont-Doherty Earth Observatory, suggests that the risk of a damaging one is not negligible. This week, the federal government announced a major upgrade to that network.
Another world lies beneath the Hudson River, as scientists have shown using pulses of sound to map the bottom. In recent years, the bathymetry maps developed at Lamont-Doherty Earth Observatory and Stony Brook University have turned up hundreds of shipwrecks and a new channel off Battery Park City, drawing interest from treasure hunters and mariners alike. Now a new group is finding inspiration: artists.
Even on a sunny day, nearly 13 million gallons of water are pumped from New York City subways. As global warming brings rising sea levels and more frequent storms, more of New York’s transit system is expected to flood.
Indian Point Nuclear Power Plant Seen As Particular Risk
A study by a group of prominent seismologists suggests that a pattern of subtle but active faults makes the risk of earthquakes to the New York City area much greater than formerly believed.
Task Force, Advised by Columbia Scientists, Will Draw Plans to Battle Rising Seas, Strains on Water and Electricity
Much of New York City’s waterfront is projected to be vulnerable to flooding in coming decades.
Ongoing Work By Scientists Will Supply Data to the Public
A frequently asked question around New York is: “Is it safe to swim? This has spurred Columbia University’s Lamont-Doherty Earth Observatory...
With the summer approaching, new research has shown that recent water emergencies in the Northeast have resulted from more than just dry weather
Buried far beneath the cattails and blackbirds of marshes in the lower Hudson Valley are pollen, seeds and other materials preserved in marsh sediment in the Hudson River Estuary. By examining this material, researchers can see evidence of a 500-year drought, the passing of the Little Ice Age, and impacts of European settlers.
Working in the subway several hours each day, subway workers and transit police breathe more subway air than the typical commuter. Subway air has been shown to contain more steel dust than outdoor or other indoor air in New York City. But do transit workers’ bodies harbor elevated levels of these metals? And does this translate into a health concern for the workers?
The Hudson River Estuary, a stretch of the Hudson River from Troy, N.Y. to its mouth in New York Harbor, has begun a new stage of its life say geologists at Columbia University's Lamont-Doherty Earth Observatory and Queens College in Flushing, N.Y. Researchers at both institutions have found that, aside from a few very specific locations, the estuary may have largely stopped filling in with new sediment.
Columbia University researchers have found that steel dust generated in the New York City subway significantly increases the total amount of airborne iron (Fe), manganese (Mn) and chromium (Cr) that riders breathe. The airborne levels of these metals associated with fine particulate matter in the subway environment were observed to be more than 100 times greater than levels observed in home indoor or outdoor settings in New York City.
