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!

The architects of Columbia’s modern Northwest Tower, at the corner of Broadway and 120th Street, made good use of some beautiful stones. In their polished and swirling surfaces, they tell a story of the clash of continents and the processes by which mountains are made.

What if you couldn’t smell smoke?
Or detect flirty signs from a bloke?
Imagine the cost
Of faculties lost,
Of signals that deafness would cloak …

At sea level, earlier flotation levels are clearly visible where the ice has been polished by the ocean’s constant movement.

This fall, the photographs of Sebastião Salgado provide the springboard for an ambitious program of panel discussions, lectures and film screenings addressing the urgent issue of climate change, at the International Center of Photography in New York City.
