    Return to Jamalganj

    We have been sailing along collecting data, but so far the data quality is poor due to shallow gas in the sediments.  We thought we might have some problems with gas, but the problem is more widespread than we expected.  We are now out of the inland summer lake where we met the boat and…

    Joining the Kokilmoni

    After a great field season last winter, we had an extraordinary opportunity this fall, a research cruise on the Bangladeshi rivers collecting geophysical data. We are using the same technique that Lamont uses on its ship, the R/V Marcus Langseth, but a mini version.  The basic idea is to use sound waves from bursts of…

    Climate Underpinnings of East Africa Drought

    Watch a video interview of climate scientist Brad Lyon on the conditions leading up to the ongoing drought in East Africa. He says there’s a chance of La Niña forming later in the year, which could have devastating consequences for a region already plagued by widespread famine.

    Undersea Clues to Haiti’s Earthquake History

    For all of its violent destruction, the earthquake that struck Haiti on Jan. 12, 2010, hardly scratched the surface of the island. But scientists now say they have found some of the best clues to understanding the quake under water.
