Scientists have recently finalized an expedition in an effort to learn more about an undersea mountain they say may have formed in a very different way than the rest of the seafloor. Aboard the JOIDES (Joint Oceanographic Institutions for Deep Earth Sampling) research ship, these scientists studied the formations and makeup of Atlantis Massif. This undersea mountain has been found to be made up of rocks typically found much deeper in the oceans crust. Other volcanic seamounts are usually...

GEOLOGY posted ahead of print 14 Feb.—2 Mar. is a dynamic collection of papers covering modeling studies of the U.S. New Madrid Seismic Zone; landslide prediction through examination of the Slumgullion landslide, Colorado; investigation of a potential nuclear waste repository site in Finland; understanding river delta formation and long-term evolution with insights from the Mekong River, Vietnam; and an explanation of how drought drove forest decline and dune building in eastern upper...

Geologists have long-debated about when plate tectonics started on the planet. One of the key indicators has been whether or not fragments of oceanic crust, generated at sea-floor spreading centers, are preserved in the planet's oldest crust. New research integrating what has been learned about the variations in modern sea floor spreading environments with the geological record of the oldest preserved crust on Earth shows that many belts in these ancient terrains have striking similarities to...

The Earth is constantly manufacturing new crust, spewing molten magma up along undersea ridges at the boundaries of tectonic plates. The process is critical to the planet's metabolism, including the cycle of underwater life and the delicate balance of carbon in the ocean and atmosphere. Now, scientists at the Woods Hole Oceanographic Institution (WHOI) have observed ocean crust forming in an entirely unexpected way"”one that may influence those cycles of life and carbon and, in turn,...

A study of the structure and evolution of the Gulf of Corinth rift in central Greece will increase scientific understanding of rifted margin development and the tectonic mechanisms underlying seafloor spreading and deformation of the Earth's crust. "The Gulf of Corinth rift is an ideal natural laboratory for studying early rift history," said Dr Lisa McNeill of the University of Southampton's School of Ocean and Earth Science (SOES) at the National Oceanography Centre, Southampton (NOCS):...

Being in the right place at the right time allowed scientists to capture and record an undersea volcanic eruption. This provided a view of the death and birth of a mid-ocean ridge from various perspectives "“ geological, biological, and geophysical -- providing new insight into the inner workings of our planet. Ordinarily, losing almost all of one's instruments would be considered a severe setback to any scientist. But when Maya Tolstoy, a marine geophysicist at the Lamont-Doherty Earth...

For the first time, scientists have produced images of the oceanic crust and found that the upper and lower layers of the crust are likely formed from different magma pools. The images begin to answer some lingering questions about where new ocean crust comes from and whether it is all formed the same way. Geophysicists Robert Detrick and Juan-Pablo Canales of Woods Hole Oceanographic Institution (WHOI) and colleagues used reflected seismic, or sound, waves to successfully image the structure...


Word of the Day
callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
