Researchers at the NYU Tandon School of Engineering are using a novel means of studying how methane and water form methane hydrate that allows them to examine discrete steps in the process faster and more efficiently.
Methane hydrate under the ocean floor was assumed to be very sensitive to increasing ocean temperatures. But a new study in Nature Communications shows that short term warming of the Arctic ocean barely affects it.
Professor Duzheng YE was decades ahead of his time in proposing a model experiment to investigate whether abrupt seasonal changes of the general circulation can arise through circulation feedbacks alone, unrelated to underlying inhomogeneities at the lower boundary. A new paper summarizes the circulation feedbacks that lead to the abrupt seasonal transitions found in the model experiments without lower-boundary inhomogeneities. It also emphasizes the work that still remains to be done to establish a comprehensive theoretical framework of seasonal transitions.
Using the most precise seafloor maps ever created of Antarctica's Ross Sea, Rice University researchers have discovered a long-dead river system that once flowed beneath Antarctica's ice and influenced how ice streams melted after Earth's last ice age. The research appears online this week in Nature Geoscience.
NOAA's GOES-East satellite has been watching the remnants for former Tropical Storm Harvey as it tracks west across the Caribbean Sea. Early on Aug. 21 the remnants were just off the coast of eastern Honduras.
Former Tropical Depression 13E has strengthened into a Major Hurricane on the Saffir-Simpson Hurricane Wind Scale. NASA's Terra satellite passed over Kenneth and captured an image that showed a well-developed storm with a visible eye.
Fish are expected to shrink in size by 20 to 30 per cent if ocean temperatures continue to climb due to climate change.
The thirteenth tropical depression of the Eastern Pacific Ocean season formed on Aug. 18. NOAA's GOES-Wet satellite captured an image of the new storm.
Tropical Storm Harvey is now moving into the eastern Caribbean Sea. NASA's GPM core satellite examined the soaking rainfall the new tropical storm was generating along its path.
Before Hurricane Gert became a post-tropical cyclone, NASA got a look at the rainfall occurring within the storm. After Gert became post-tropical NOAA's GOES-East satellite captured an image as Gert was merging with another system.
