    Every (Fifth) Breath We Take: Friends of Phytoplankton and Why They Matter

    Tiny microbes called phytoplankton live beneath the ocean’s surface, producing oxygen that is essential to human survival. A new study sheds light on how these all-important diatoms survive and thrive under difficult conditions.

    Exploring the Microbiome of an Ocean Bacteria

    Braving the high seas and a curious shark, a team of scientists taps into the secret social life of a microbe that’s crucial for marine ecosystems.

    Subsurface Discovery Sprouts a New Branch on the Tree of Life

    Last week a study published in Nature pulled the veil on a branch of the bacterial tree of life that has evaded detection for nearly a century and a half. The study used cutting edge genome sequencing and savvy bioinformatics techniques to make this remarkable discovery.

    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…

    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.

    Trichodesmium is Everywhere!

    We have completed the first two stations of the OUTPACE cruise and we are steaming to Station 3. By noon tomorrow we should be in the center of an eddy that our colleagues back on dry land have used satellite data to identify.

    OUTPACE Cruise: Setting Sail

    The OUTPACE 2015 cruise has set sail on February 20! We left port in Nouméa at 8:30 a.m. last Friday morning. I lost sight of land around 10 a.m. or so, and I won’t see it again until we return to port in Papeete, Tahiti on April 3.

    Graduate students, microbe goo … What is it that links the two? It seems that both life forms are found Where electron donors (food) abound!
