Antarctic Canyons Channel Warm Water, Accelerating Ice Sheet Melting

Antarctic canyons play a critical role in the melting of the East Antarctic Ice Sheet by channeling relatively warm Circumpolar Deep Water to its base, a new study reveals. Led by the National Institute of Oceanography and Applied Geophysics (OGS), researchers discovered sedimentary formations within these canyons, indicating persistent bottom currents that transport ocean heat.

Evidence for New Groups of Methane-Producing Organisms Discovered

A team of scientists from Montana State University has provided the first experimental evidence that two new groups of microbes thriving in thermal features in Yellowstone National Park produce methane — a discovery that could one day contribute to the development of methods to mitigate climate change and provide insight into potential life elsewhere in our solar system.
