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.

The world’s oceans are growing more acidic as carbon emissions from the modern world are absorbed by the sea. A new film, “A Sea Change,” explores what this changing chemistry means for fish and the one billion people who rely on them for food. This first-ever documentary about ocean acidification is told through the eyes of a retired history teacher who reads about the problem in a piece in The New Yorker and is inspired to find out more. His quest takes him to Alaska, California, Washington and Norway to talk with oceanographers, climatologists and others.

“Drain the Ocean” will be aired Sunday, August 16, 2 p.m. on the National Geographic channel. The special put computer-generated imagery and digital mapping technology to imaginative use through showing what the oceans would look like if all their water was emptied through an imaginary drain. The result would be a landscape far more dramatic than anything on dry land, including a 40,000 mile-long mountain range, the world’s deepest canyon and widest plains, and bizarre, bioluminescent life forms

Instead of an ice-covered South Pole, picture sub-tropical temperatures and flowering plants. That’s what parts of Antarctica looked like 85 million years ago. How long ago was that? If you’re drawing a blank you’re not alone.
Thinking on geologic time scales does not come easily for many people, and that’s a challenge in teaching earth science, says Lamont-Doherty oceanographer Kim Kastens, in a recent cover story in EOS, a weekly newspaper published by the American Geophysical Union.

", broadcast on July 7th & July 9th 2009 as part of a three part series on energy and climate.
As politicians and environmentalists prepare for the UN Climate Change talks in December to discuss urgent reduction of CO2 emissions, the BBC asked what is the future for global energy production?

U.S. scientists working on a research vessel in the Gulf of Mexico have made the most promising discovery so far of marine gas hydrate, a possible new energy source.
Potential Alternative Fuel, Usually Too Thinly Spread to Exploit

The oceans play a central role in cycling carbon dioxide into and out of the atmosphere, and thus an essential role in regulating climate. Taro Takahashi, a geochemist at Lamont-Doherty Earth Observatory, has spent the last five decades measuring this process, and the April issue of the journal Deep Sea Research II is dedicated to him for this pioneering work.

Researchers have reconstructed atmospheric carbon dioxide levels over the past 2.1 million years in the sharpest detail yet, shedding new light on its role in the earth’s cycles of cooling and warming.

A power plant in Iceland is set to become the first in the world to try turning carbon dioxide emissions into solid minerals underground, starting this September.
In an $11 million pilot project, Reykjavik Energy will capture CO2 from its plant, dissolve the gas in water and inject it deep into volcanic basalt nearby. Over the nine-month study, some 2,000 tons of greenhouse gas will be treated.

Seismologists, Pinpointing Location, See Little Doubt It Was Bomb
Seismologists who have intensively studied North Korea’s nuclear testing efforts say Monday’s blast was certainly a nuclear bomb, roughly five times larger than the country’s first test in 2006.

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.

The new Gary C. Comer Geochemistry Building at Columbia University's Lamont-Doherty Earth Observatory in Palisades, N.Y., has won three top architecture awards. Recognized for its environment-friendly features, the building houses more than 80 staff, many of whom have long been at the forefront of global climate research. Scientists in Lamont's geochemistry division study the movements and interactions of substances in air, oceans, groundwater, biological remains, sediments and rocks.

Landslides kill thousands of people each year but because they're often triggered by earthquakes or heavy rains, the danger remains poorly understood. A PhD candidate at Lamont-Doherty Earth Observatory has put together a global catalog of recent mudslides to help scientists better predict where and when the next one will occur.

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.
