The distribution of spreading oceanic ridges, and oceanic plateaus or aseismic ridges in the world Credit: Science China Press   ENLARGE Generally speaking, ‘ridge subduction’ involves subduction of spreading oceanic ridges, aseismic ridges or oceanic plateaus and inactive arc ridges, and this common and important geological process has become one of […]

Even if the climate cools, study finds, glaciers will continue to shrink. Nearly 40 years of satellite data from Greenland shows that glaciers on the island have shrunk so much that even if global warming were to stop today, the ice sheet would continue shrinking. The finding, published today, Aug. […]

July 2, 2020. (Click HERE for full detailed view.) Arctic sea ice is subject to some serious travel restrictions. Penned in by major land masses, most ice that forms in the Arctic Ocean stays there for the duration of its existence—typically one to four years before melting. Some ice, however, […]

The hybrid remotely-operated vehicle Nereus was used to collect seafloor samples, in addition to remotely operated vehicle Jason II, at Piccard vents at Mid-Cayman Rise. Credit: Jill McDermott Scientists analyzing hydrothermal fluid from Piccard vents at Mid-Cayman Rise find non-biological processes deplete hydrogen that was thought to be readily available […]

ANIMATION An international team discovered a previously unrecognized ocean current that transports water to one of the world’s largest “waterfalls” in the North Atlantic Ocean: the Faroe Bank Channel Overflow into the deep North Atlantic. While investigating the pathways that water takes to feed this major waterfall, the research team […]

For Steven Fons, returning home to D.C. in June was like coming back from another planet. “It was totally surreal. The grass and the trees were greener than I remembered,” recalled Fons, an atmospheric and oceanic […]
