    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…

    Tiger Footprints and Dhaka

    We finished our time in the Sundarbans with a silent boat ride in a tidal creek. The highlight was sets of fresh tiger footprints. We then had a long sail back to Dhaka with only one stop at a village. We then had a whirlwind tour of Old Dhaka with enough shopping to send the…

    Salt Kilns and Landscape Change in the Sundarbans

    Leaving Hiron Point, we headed east through the Sundarbans to Kotka. At Kotka the students had walks through the forest seeing deer, wild boar and monkeys, while a smaller group also sampled near a set of 300 year old salt making kilns for OSL dating. We managed to finish while the tide inundated the site.…

    Polder 32 and Hiron Point

    We visited Polder 32, an embanked island in the delta that was flooded for almost two years when the embankment failed in several places during Cyclone Aila. In addition to the problem of increased subsidence due to the embankment, the area struggles for fresh water. Then we sailed to Hiron Point, a forest station in…

    Creating a ‘Safe Space’ for Iconic Ecosystems

    Important global ecosystems like the Amazon rainforest and Great Barrier Reef are in danger of breaking down because of a combination of local pressures and climate change, but better local management could help make these areas more resilient.

    Sampling up a Storm

    I’m writing from where L’Atalante is currently parked, 18S 170W, right in the middle of a giant, anomalously high sea surface chlorophyll patch. Such a high concentration of chlorophyll—a pigment that helps photosynthetic organisms harvest energy from sunlight, and the one that’s responsible for the green color of plants—can mean but one thing in the…

    Navigating the South Pacific Using DNA

    I’ve never been good at navigating. When I come out of the subway I invariably turn the wrong direction, even though I already have my nose buried in Google Maps, and then walk around the block to save face.

    Greetings from the center of that eddy I mentioned in my last post! We’ve been here for five days so far, but tomorrow we are finally moving on.
