    Starving the Oceans

    Nutrients increasingly moving to the deep ocean with strong climate warming could lead to drastic drops in surface ocean life and fishery yields.

      Phytoplankton: the foundation of the oceanic food chain.

    The Science

    Researchers examined the impacts of sustained climate warming on the oceans. In an Earth system model simulation, they examined how the oceans would change through the year 2300 with continued strong warming conditions. They found that upper ocean nutrient concentrations declined globally. The nutrients that support phytoplankton and marine ecosystems are increasingly transferred to the deep ocean.

    The Impact

    Sustained multi-century climate warming could drive a net transfer of nutrients to the deep ocean. This transfer affects the global fishery yield and other organisms near the ocean surface. Fishery yields could drop by 20 percent globally by 2300; the North Atlantic Ocean could see fishery yields drop by nearly 60 percent.

    Summary

    The primary pathway for nutrient-rich, deep ocean waters to return to the surface is in the Southern Ocean surrounding Antarctica, at the Antarctic Divergence. Here, upwelling brings deep waters up to the surface. These nutrient-rich waters drift northwards, eventually subducting to form sub-Antarctic Mode and Antarctic Intermediate waters at mid-depths. The nutrients transported northwards in these waters feed much of the biological productivity, or life in the oceans. With sustained, multi-century climate warming, researchers found that shifting winds, warming surface waters, and melting sea ice drive increased biological production around Antarctica. This leads to local trapping of nutrients and reductions in the northward lateral transport of nutrients that fuel marine ecosystems worldwide. This drives 1) a net transfer of nutrients to the deep ocean and 2) depletion of depletes nutrients in the upper ocean, which depresses marine biological productivity at the global scale.

    Funding

    This research was performed for the Reducing Uncertainties in Biogeochemical Interactions through Synthesis and Computation Scientific Focus Area, which is sponsored by the Earth and Environmental System Modeling Program (EESM), under the Regional and Global Climate Model Analysis activity. Additional support came from projects sponsored by the EESM Earth System Modeling (ESM) activity. EESM is part of the Climate and Environmental Sciences Division of Biological and Environmental Research in the Department of Energy Office of Science.

    Neutrons paint atomic portrait of prototypical cell signaling enzyme

    Direct observations of the structure and catalytic mechanism of a prototypical kinase enzyme--protein kinase A or PKA--will provide researchers and drug developers with significantly enhanced abilities to understand and treat fatal diseases and neurological disorders such as cancer, diabetes, and cystic fibrosis. The discovery was made by an international team of researchers using macromolecular neutron crystallography at the Department of Energy's Oak Ridge National Laboratory and the Institut Laue-Langevin in Grenoble, France.

    Bright Skies for Plant-Based Jet Fuels

    With an estimated daily fuel demand of more than 5 million barrels per day, the global aviation sector is incredibly energy-intensive and almost entirely reliant on petroleum-based fuels. However, a new analysis by scientists at Berkeley Lab shows that sustainable plant-based bio-jet fuels could provide a competitive alternative to conventional fuels if current development and scale-up initiatives continue to push ahead successfully.

    A team of scientists including researchers at the U.S. Department of Energy's (DOE) Brookhaven National Laboratory and SLAC National Accelerator Laboratory have identified the causes of degradation in a cathode material for lithium-ion batteries, as well as possible remedies. Their findings, published on Mar. 7 in Advanced Functional Materials, could lead to the development of more affordable and better performing batteries for electric vehicles.

    Uncovering Uncultivated Microbes in the Human Gut

    Uncovering Uncultivated Microbes in the Human Gut

    A human's health is shaped both by environmental factors and the body's interactions with the microbiome, particularly in the gut. Genome sequences are critical for characterizing individual microbes and understanding their functional roles. However, previous studies have estimated that only 50 percent of species in the gut microbiome have a sequenced genome, in part because many species have not yet been cultivated for study.

    Scientists Track Patterns of Island Growth in Crystals

    In a new study from the U.S. Department of Energy's (DOE) Argonne National Laboratory, scientists have found that the seemingly random arrangement of islands that form to begin new layers during crystal growth can actually be very similar from layer to layer. The discovery may help scientists better understand of some of the mechanisms behind defect formation, as well as develop techniques to synthesize new types of crystals.
