12K views · 92 reactions | In Nature Geoscience, researchers describe a geological structure that restricts ocean water flows around the Ross Ice Shelf, Antarctica. The discovery suggests local ocean currents may play a critical role in the ice shelf's future retreat. Read the paper: https://go.nature.com/2wrkNTO | Nature Portfolio | Facebook

Earth’s Inner Core Is Slowing Down | Seismic Discovery & Magnetic Field Impact Seismic studies reveal that Earth’s solid inner core does not rotate at a constant rate. Since around 2010, it has slowed slightly, lagging behind the mantle and crust. Scientists detected these changes by analyzing tiny differences in seismic wave arrival times through the iron-rich core. This slowdown affects the geodynamo, influencing Earth’s magnetic field and the flow of liquid iron in the outer core. Understandi
