With modern computing power and innovative analytical skills, scientists at Scripps Institution of Oceanography at UC San Diego and their colleagues have constructed the most detailed imagery to date of a massive active magma chamber located off the Pacific Northwest where Earth’s plates are spreading the seafloor apart. Scientists including Scripps postdoctoral researcher Adrien Arnulf […]
Starting June 25, UH Mānoa will lead an expedition to Loihi Seamount, southeast of the island of Hawaii, whose base remains largely unexplored. Dr. Brian Glazer, lead scientist and Associate Professor of Oceanography, his team from UHM, and colleagues from the University of Minnesota, IFREMER Centre de Brest and Woods Hole Oceanographic Institution (WHOI), will […]
Recently, scientists have described what is being called the largest volcano on the planet. In an article in the journal Nature Geoscience, Dr. William Sager and his coauthors present evidence from multichannel seismic and core data indicating that the province known as the Tamu Massif is a shield volcano several hundred kilometers across. The site, […]
Since the plate tectonics revolution of the 1960s, scientists have known that new seafloor is created throughout the major ocean basins at linear chains of volcanoes known as mid-ocean ridges. But where exactly does the erupted magma come from? Researchers at Scripps Institution of Oceanography at UC San Diego now have a better idea after […]
In August 2012, scientists conducted an intensive geological survey of the submarine rhyolitic Omurodashi volcano located south of Izu-Oshima, Tokyo Metropolis, using the remotely operated vehicle (ROV) Hyper Dolphin. The survey, led by Kenichiro Tani, Research Scientist, Institute for Research on Earth Evolution (IFREE) Japan Agency for Marine-Earth Science and Technology (JAMSTEC), is the first […]
The new multi-purpose research vessel R/V Ramon Margalef, which belongs to the Spanish Oceanographic Institute (IEO), was undergoing sea trials when the Science Ministry decided to move it to the Canary Islands to follow up on the activity of the volcano on El Hierro Island. The vessel was only delivered a few weeks previously, on […]
Scientists have taken just a fortnight to map the creation of an underwater volcano in high resolution. After picking up seismic waves on… (Earth Times) Source: Earth Times, November 01, 2011;
An underwater eruption which kicked off on Monday at two-and-a-half kilometres from the coast of El Hierro is now said to be in waters of less than 150 metres in depth. Experts say that when the eruption reaches its full force, white columns of vapour will be seen from far and wide. The volcanic ‘stain’ […]
Two new volcanic eruptions were confirmed on Wednesday off the south coast of the Canary Island of El Hierro… By Mark Johanson (ibtimes) Source: ibtimes, October 14 , 2011;
Skidaway Institute of Oceanography scientist Aron Stubbins joined a research cruise this summer to study hydrothermal vents, but what his fellow scientists found was a recently erupted undersea volcano. The Axial Seamount is an undersea volcano located about 250 miles off the Oregon coast and is one of the most active and intensely studied […]
