Ice shelf collapse reveals early warning signs of melt
Scientists found that growing fractures caused an East Antarctic ice shelf to collapse.
Carbon feedbacks 56 million years ago similar to today
Geologists simulated the chemistry of Earth's past oceans and atmosphere using mineral data from the ancient seafloor. They found a…
Volcanism warmed past Earth
Geologists dated a global warming event about 180 million years ago. They found it lasted between 169,000 and 417,000 years and was linked…
Methane-munching microbes modify the seafloor
Researchers showed that methane-eating bacteria acidify their surroundings and dissolve carbonate rocks on the seafloor.
How will the melting Greenland Ice Sheet affect ocean currents?
Researchers found the melting Greenland Ice Sheet is releasing tons of icebergs into the North Atlantic Ocean that could further disrupt…
Could “iron snow” fuel life in Europa’s ocean?
Scientists calculated that microorganisms breathing iron oxide “snow” could produce enough energy to survive on Jupiter's icy moon…
Dolphins have special whistles for their young
Researchers found bottlenose dolphins modify the pitch and range of whistles when communicating with their calves, similar to how humans…
Northern elephant seals sleep in a deep diving spiral
Scientists tracked the brain activity of northern elephant seals to find out how they sleep. They found the seals sleep only 2 hours per day…
