Oxygen-depleted toxic oceans had key role in mass extinction over 200 million years ago
Changes in the biochemical balance of the ocean were a crucial factor in the end-Triassic mass extinction, during which half of all plant, animal and marine life on Earth perished, according to new research ...
Expect quiet hurricane season, researchers say
The 2015 Atlantic hurricane season will be significantly less active than the overall averages from 1950 to the present, according to researchers at North Carolina State University.
New form of ice could help explore exciting avenues for energy production and storage
Clathrates are now known to store enormous quantities of methane and other gases in the permafrost as well as in vast sediment layers hundreds of metres deep at the bottom of the ocean floor. Their potential ...
Scientists find deep-ocean evidence for Atlantic overturning decline
A new study has found evidence from the deep ocean that the Atlantic meridional overturning circulation – a system of currents that brings warm water from the tropics to the North Atlantic region and keeps ...
Geologist identifies new source of methane for gas hydrates in Arctic
Research led by a University of New Hampshire professor has identified a new source of methane for gas hydrates—ice-like substances found in sediment that trap methane within the crystal structure of frozen ...
Sea change: What took decades to destroy in oceans took millennia to recover
Ocean ecosystems that experience rapid upheaval because of climate change can take thousands of years to recover, according to an examination of fossilized ocean fauna on the seafloor by the University of ...
Satellite images reveal ocean acidification from space
Pioneering techniques that use satellites to monitor ocean acidification are set to revolutionise the way that marine biologists and climate scientists study the ocean. This new approach, that will be published ...
