    A Recovery Mission

    Recovery Glacier is a section of Antarctic ice that lies east of the peninsular arm of West Antarctica, tucked behind the Transantarctic Mountains, a dividing line that separates west from east. We know from satellite data that Recovery and its tributaries have a deep reach, stretching well inland. But there is a lot we don’t…

    Hiron Point in Sundarban

    We traveled by boat to the south part of the Sundarbans near the Indian Ocean to install a GPS at Hiron Point, this isolated facility also hosts a tide gauge recording long-term water level changes due to rising sea level and land subsidence. Our GPS will help distinguish how much of each there is in…

    Polder 32

    Polder 32 is one of the many inland islands in Bangladesh that was enclosed by an embankment to protect it from flooding. When that embankment failed during Cyclone Aila in 2009, the island was flooded for almost 2 years. Subsidence of the ground inside the embankment with no sedimentation to compensate made it worse. We…

    Khepupara to Kokilmoni

    Leaving Dhaka, we spend an entire day getting to Khepupara in southern Bangladesh. Then we spent a long morning installing a GPS to monitor subsidence of the delta before heading back on the road again.

    The New Climate Dice: The Odds Have Shifted to Hot

    This year’s Midwest heat wave and some other recent extreme weather events are no fluke of nature, but a consequence of a warming planet, according to an analysis of climate data by NASA scientists.
