The deep sea is home to “dark oxygen”

The Economist  

Listen to this story. Any oxygen found in regions where photosynthesis is impossible—such as the abyssal seafloor, a pitch-black realm up to 6,000 metres deep—was thought to be surface gas on the move. In a paper published in Nature Geoscience, however, Andrew Sweetman at the Scottish Association for Marine Science and his colleagues reveal that some is, in fact, “dark …

Marine heatwaves are sweeping the seafloor around North America

The Hindu  

Heatwaves unfolding on the bottom of the ocean can be more intense and last longer than those on the sea surface, new research suggests, but such extremes in the deep ocean are often overlooked. A team of scientists with the U.S. National Oceanic and Atmospheric Administration have conducted the first assessment of marine heatwaves along North America's continental shelves. "We …

Scientists Solve the Mystery of How Methane Escapes through Ice Caps from Deep Sea-beds

News 18  

Methane is considered as one of the cleanest fossil fuels to burn, however, when released in the atmosphere, it becomes one of the worst greenhouse gases writing the doom of our planet through global warming. Global observations have shown robust methane gas columns as they bubble upwards from their frozen grave called methane hydrates. Lead author Xiaojing Fu observed photos …

By contrast, in the middle of the Pacific, there’s surely life, just a lot less of it. “It's the least-explored large biome on Earth, because it covers 70 percent of Earth's surface,” says the University of Rhode Island's Steven D’Hondt, who co-led the expedition and coauthored a new paper in Nature Communications describing the findings. “If you trawl through the …
