    Yes, These Flesh-Eating Algae Are Real. And They Like Their Prey Alive.

    New research suggests that photosynthetic green algae also eat bacteria on a previously unsuspected scale.

    Metals From Chinese Smokestacks Are Landing Far Away in the Pacific Ocean

    Emissions from coal-fired power plants and possibly other sources in China are seeding the North Pacific Ocean with metals including iron, according to new a new study.

    Fueled by Melting Glaciers, Algae Bloom Off Greenland

    Iron particles catching a ride on glacial meltwater washed out to sea are likely fueling a recently discovered summer algal bloom off the southern coast of Greenland, according to a new study. Microalgae, also known as phytoplankton, are plant-like marine microorganisms that form the base of the food web in many parts of the ocean.…

    Study Reveals Microbes’ Hidden Role in Fertilizing Oceans

    Surprisingly little has been known about how phosphorous, an essential nutrient, cycles through the oceans. A new study has broken through some of this mystery, by showing the hidden role that the oceans’ tiniest creatures play.

    On skin, it’s barely a freckle I’d make, But baby, en masse, we turn seas opaque! Come darkness, come famine, come poison or flood, My kind can flourish in any old crud.

    A Tale of Sea Ice, Algae and the Arctic

    I returned to New York on Monday, but Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack remain working in Barrow, Alaska for another week. They’ll continue to collect data and samples in a race against deteriorating Arctic sea ice conditions as the onset of summer causes the ice to thin and break up.

    Science, Creativity and Isopods

    It’s near midnight and Lamont-Doherty Earth Observatory researchers Andy Juhl and Craig Aumack, and Arizona State’s Kyle Kinzler are gathered around a table in their lab at the Barrow Arctic Research Consortium discussing the best way to catch an isopod.

    Ctene Sensations of the Arctic Ocean

    One of the goals of Andy Juhl’s and Craig Aumack’s Arctic research is to determine the role of ice algae as a source of nutrition for food webs existing in the water column and at the bottom of the Arctic ocean.

    Collecting Core Data About Arctic Ecosystems

    Our team spent most of Friday on the Arctic sea ice, drilling and sampling ice cores at our main field site. For each core collected, Lamont-Doherty Earth Observatory scientists Andy Juhl and Craig Aumack take a number of different physical, chemical and biological measurements
