SeismoDome

Lamont-Doherty Earth Observatory scientist Ben Holtzman grew up discovering science through interactive exhibits in San Francisco’s Exploratorium and now provides a similar experience for others. Holtzman designs immersive shows that allow people to experience what earthquakes and seismic waves look and sound like as they move through and around the Earth. On Monday, November 17th at the American Museum of Natural History Hayden Planetarium, Holtzman and his collaborators will present one of these shows, the second installment of SeismoDome: Sights and Sounds of Global Seismology.

NASA has been at the forefront of climate science, launching satellites that take the pulse of Earth’s land, oceans and atmospheric systems. But the agency is increasingly vulnerable itself to the effects of a changing climate.

Once a year, Piermont Pier becomes a field station, and local students, a team of environmental investigators. On Tuesday, scientists at Lamont-Doherty Earth Observatory led students through a series of field experiments designed to teach them more about the Hudson River.

Visitors to Lamont-Doherty Earth Observatory’s open house on Oct. 11 could tune in to a performance of “Salty Folk” by Superhero Clubhouse, a collective of artists and environmental advocates. Created by Jeremy Pickard and Nate Weida, the play uses music and humor to illustrate the history and importance of New York Harbor through the “eyes” of five oysters: Brook, Manny, Bronxy, Queeny and Stats.

New pictures in the journal Nature Geoscience may help resolve a debate about how new crust forms at mid-ocean ridges where earth’s tectonic plates are slowly pulling apart.

Frozen into the stone floor of a stairway landing, several flights up in Columbia’s Lewisohn Hall, sits a stark reminder of how life has evolved in the sea. Part 6 of the Columbia Geology Tour.

Sun-gazing

Dopplergrams from the NASA's space telescope IRIS (Interface Region Imaging Spectrograph) revealing detailed evidence of "twist" between the sun's surface and outer atmosphere. These phenomena may play a role in driving the temperature difference between the sun's surface (~6000 K) and the sun's outer atmosphere (millions of degrees). The reason for this enormous temperature gradient is not fully understood (a puzzle known as the "coronal heating problem"). Image: De Pontieu et al., Science 2014

By Galileo’s careful hand, sunspot details are exquisite,
Through eye of forehead, eye of mind beholds what body can not visit.
If only he could see the sights now rendered from Earth’s outer space,
Ultraviolet sunscapes – Oh, to see his raptured face!

“Climate change has been making the fire season in the United States longer and on average more intense,” said John Holdren, President Obama’s science advisor. And, wildfires are not only intensified by climate change, they also exacerbate it.
