Does the Arctic Ocean regulate or amplify global warming?
Researchers found that interactions between methane gas and seawater affected greenhouse gas emissions from the Arctic Ocean during a past…
Why the 2023 El Niño broke records
Researchers found that the 2023 El Niño event was fueled primarily by heat stored in the ocean rather than in Pacific winds.
Why do deep-sea microbes have such small appetites?
The deep sea is one of Earth’s largest reservoirs of carbon, yet microbes don’t consume very much of it. Researchers showed that this is…
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…
