An Earth Epic
I hear that the Archean Earth Spewed lava and was hot, (While much later, “Snowball Earth,” Apparently was not), Some have said that life sprung out of Spreading-ridge-type stew, Photosynthesis seems likely Based on carbon records, too.

In the Ice
Several days ago we reached our main work areas along the margin of East Antarctica. Our expedition is relatively late in the season and the seas around Antarctica are starting to freeze.

Closing in on Antarctica
We are less than a day away from our first study area on the continental shelf in front of the Dibble Glacier. As we approach Antarctica we are starting our science program with a 4500 meter deep CTD and multibeam acquisition.

Indian Sundarban
We arrived in Kolkata, and filmed by the Hooghly River. While it is no longer the main channel of the Ganges, it is still the Holy Ganges and we saw a funeral procession spreading ashes of a loved one while filming there. Then a 5 hour trip by car, ferry, rickshaw and boat to the…

On Our Way: Avoiding the Storm
We are now aboard the R/V Palmer and on our way to East Antarctica. Due to two storms in our direct way we are heading west first to go around the storms and we’ll then head south on their backside.

Geology and Filming in Mizoram
In the small town of Kolasib, we stayed in Hotel Cloud 9. I had been told since I was a child that I was always off on Cloud 9 and now I was actually here. However, the electricity wasn’t for the first few hours, so showers were cold, but the dinner was hot.

Soon-to-End Mercury Mission May Hold Clues to Earth’s Evolution
NASA’s MESSENGER spacecraft has been orbiting Mercury for the last four years, giving scientists an unprecedented look at our solar system’s innermost planet. But now the craft’s fuel supply is exhausted; inexorably drawn in by Mercury’s gravity, it is scheduled to crash in April. Sean Solomon, director of Columbia University’s Lamont-Doherty Earth Observatory, has been…

Mapping Faults Hidden below Lake Malawi
Marine seismic studies like ours are routinely done in the oceans using scientific equipment and research vessels outfitted specially for these purposes. Collecting comparable data in a great lake in Africa requires creative repurposing of available vessels and adaption of scientific equipment.

Adapting to the Unexpected
I grew up outside of Chicago and I wasn’t a Boy Scout, so sometimes I feel like I missed out on learning the type of practical—albeit rarely used—skills that would have garnered merit badges. Now that I’m nearing the conclusion of my fourth research expedition at sea, I think I have amassed a few badge-worthy…
By studying thousands of buildings and analyzing their electricity use, Columbia Climate School Dean Alexis Abramson has been able to uncover ways to significantly cut energy consumption and emissions. Watch the Video: “Engineering a Cooler Future Through Smarter Buildings“
