    Northern New Jersey, southern Connecticut and environs are not necessarily where one would expect to explore the onetime extinction of much life on earth, and subsequent rise of dinosaurs. But it turns out to be a pretty good place to start. Underlying the exurbs are geological formations left by three giant episodes of volcanism starting around 200 million years ago, and intervening layers of sediments that built up in the interims between massive lava flows.

    Researchers from Lamont-Doherty Earth Observatory and the Earth Institute work on every continent and every ocean; journalists are welcome to cover projects in the field or otherwise contact scientists.  Below: selected expeditions worldwide, in rough chronological order. (New York/Hudson Valley is listed separately.)  Journalists or employers must pay travel expenses. Photos, blogs and phone/email from field sites will be available in many cases.  Blogs are accessible from the Lamont-Doherty home page and the Earth Institute’s State of the Planet pages. An updated version of this list is kept on our Media Advisory page. Unless otherwise stated, projects originate with our Lamont-Doherty Earth Observatory.

    Columbia University is joining a growing movement among universities and research institutions to make scholarly research available free to the public online. Lamont-Doherty Earth Observatory is the first program at the university to adopt an open access resolution, which calls for faculty and other researchers to post their scientific papers in online repositories such as Columbia’s Academic Commons.

    Columbia scientists have played a pioneering role in understanding climate change, from its potential effect on critical resources such as water and energy to finding ways vulnerable communities can better adapt.

    Columbia University's the Record devotes its January 31, 2011 issue to climate matters, and Lamont-Doherty researchers feature prominently.
