Big data imaging shows rock's big role in channeling earthquakes in Japan

Posted: 07 Feb 2022 09:48 AM PST

Thanks to 20 years of seismic data processed through one of the world's most powerful supercomputers, scientists have created the first complete, 3D visualization of a mountain-size rock called the Kumano Pluton buried miles beneath the coast of southern Japan. They now see the rock could be acting like a lightning rod for the region's megaquakes, diverting tectonic energy into points along its sides where several of the region's largest earthquakes have happened.

Jet stream models help inform US offshore wind development

Research revises estimates of glacial ice volume, suggesting that there is less ice in the world's glaciers than previously thought. The findings have implications on freshwater and global sea level rise.

Shifting rainfall patterns will affect whether an imperiled butterfly survives climate change

Posted: 07 Feb 2022 07:01 AM PST

When we think of climate change, we often imagine how a warmer world will impact species, but a new study highlights the importance of changes in precipitation. The finding suggests that paying attention to the environmental triggers within each species' lifecycle will help us better understand how they will be affected by climate change.

Deep insights into the Arctic of tomorrow

Hundreds of international researchers are currently analyzing observations from the one-year MOSAiC expedition, during which hundreds of environmental parameters were recorded with unprecedented accuracy and frequency over a full annual cycle in the Central Arctic Ocean.

The Congo tropical forest is simply different

Posted: 07 Feb 2022 05:34 AM PST

Until now, research assumed that the vast forest area of the Congo Basin, like other tropical forests, releases large amounts of nitrous oxide and binds methane. Researchers have now shown that it behaves differently: methane is released, while nitrous oxide emissions are smaller than thought.

Only 15 per cent of global coastal regions remain intact
