1. Oceans

    Deepwater Horizon methane lingered longer than thought

    Microbes may not have consumed methane from the 2010 Deepwater Horizon oil spill as fast as previously thought.

  2. Animals

    Secrets of a sailfish attack

    The large, long-nosed sailfish use their rostrums more like a sword than a spear to attack prey.

  3. Climate

    Reef fish act drunk in carbon dioxide–rich ocean waters

    In first test in the wild, fish near reefs that bubble with CO2 lose fear of predators’ scent.

  4. wood-boring clam

    The surprising life of a piece of sunken wood

    Timber and trees that wash out to sea and sink to the bottom of the ocean hold a diverse community of organisms.

  5. Climate

    Ocean bacteria may have shut off ancient global warming

    Ocean-dwelling bacteria may have helped end global warming 56 million years ago by gobbling up carbon from the CO2-laden atmosphere.

  6. Earth

    How the Chicxulub impact made acid rain

    Using lasers to accelerate materials to asteroid-like impact velocities, scientists have shown how the Chicxulub asteroid impact, which happened roughly 65 million years ago, could have created a mass extinction in the oceans.

  7. Animals

    Spotted seals hear well in and out of water

    Spotted seals, native to the northern parts of the Pacific, hear frequencies that may mean they are susceptible to the effects of anthropogenic noise.

  8. ambon damselfish

    Fish lose their fear on a denuded reef

    Juvenile damselfish lose their ability to smell danger when in a degraded habitat.

  9. Oceans

    Unknowns linger for sea mining

    Scientists struggle to predict underwater digs’ effects on sea life.

  10. Climate

    Sharks could serve as ocean watchdogs

    Tagged with sensors, toothy fish gather weather and climate data in remote Pacific waters.

  11. Environment

    How oil breaks fish hearts

    Hydrocarbons that spill into oceans stifle the beat of tuna cardiac cells.

  12. Climate

    Strong winds may have waylaid global warming

    Gusts over the Pacific Ocean may have stashed heat underwater since 2001.
