    Scientists Drill 2 Miles Down to Ancient Lake Vostok

    Russian scientists this week finished penetrating more than two miles through the Antarctic ice sheet to Lake Vostok, a huge freshwater lake that has been buried under the ice for millions of years. But they won’t know what they’ve found until next year.

    The good ‘ol forest growth curve [update]

    While the New Jersey bill failed, it is going to be discussed in New Jersey’s Senate Environment Committee on Monday, January 30, 2012. The discussion is not yet over regarding New Jersey’s public forests. The discussion about ecosystem productivity over time also continues in the forum of the Native Tree Society. Specifically, this post was picked…

    Ohio Quakes Probably Triggered by Disposal Well, Say Seismologists

    Earthquakes that have shaken an area just outside Youngstown, Ohio, in the last nine months are likely linked to a disposal well for injecting wastewater used in the hydraulic fracturing process, say LDEO seismologists.

    Arboreally Speaking, the ‘Good Old Growth Curve Is a Delusion’

    In the previous post, I outlined the argument lighting up parts of the New Jersey legislature and the human elements of its ecological communities. Briefly, one reason some people are using to promote logging on public lands is the perception that old trees and forests are dying of old age. While there are other arguments…

    Holidays on the High Seas

    With round-the-clock shifts, there are precious opportunities for Santa to slip onto a research ship unseen. But slip in he did, leaving treats and gifts around the R.V. Langseth to brighten our day.

    Retrieving Instruments from the Deep

    Over the first 22 days aboard the R/V Marcus G. Langseth, we’ve zigged and zagged our way over a 360×240 mile region of the Pacific plate, first dropping instruments to the seafloor, and then shooting airguns to them (see previous posts). The final step is to recover a subset of the instruments:  34 ocean-bottom seismometers…

    The Art of Sound in the Ocean

    The NoMelt experiment aims to image the structure of an oceanic plate, including its deepest reaches up to 70 km beneath the seafloor.  One of our primary means to do so is to create sound (acoustic) waves in the ocean from the ship, and record those waves at receivers on the seafloor, after they have…

    Earth Institute Science in Spotlight

    Research presented by Earth Institute scientists at the 2011 American Geophysical Union fall conference generated a lot of attention from the media. Much of it came from a press conference held to discuss findings by Steve Goldstein from the Lamont-Doherty Earth Observatory and his colleagues on the potential for future drying up of the Dead…
