“Kavachi is an undersea volcano on the southern edge of the Solomon Islands in the western Pacific Ocean. It erupted dozens of times in the 20th century, often breaking the water surface, only to be eroded back below the water line within a few months.” Satellite view from NASA Earth Observatory.
“This visualization shows ocean surface currents around the world during the period from June 2005 through Decemeber 2007. The visualization does not include a narration or annotations; the goal was to use ocean flow data to create a simple, visceral experience.” Quoted from the NASA YouTube Channel.
Marine scientists working on the coral reefs of Palau have made two unexpected discoveries: 1) at each location they found that the seawater became increasingly more acidic as they moved toward land; and, 2) the corals living in those more acidic waters were unexpectedly diverse and healthy.
“Los Angeles, a metropolis perched on the edge of a coast, can expect to experience sea level rise of as much as two feet due by 2050 due to climate change, according to current projections.” Quoted from the USC press release.
“Although few people live in the Western tropical Pacific Ocean region, the remote waters there affect billions of people by shaping climate and air chemistry worldwide.
Next week, scientists will head to the region to better understand its influence on the atmosphere–including how that influence may change in coming decades if storms over the Pacific become more powerful with rising global temperatures.” Quoted from the NSF press release.
“An investigation of the most powerful earthquake ever recorded deep within the Earth suggests deep quakes may be better at dissipating pent-up energy than similar quakes near the surface.” Quoted from the NBC News story.
“The chance transit of a satellite over the April 2009 eruption of Fernandina volcano — the most active in South America’s famed Galápagos archipelago — has revealed for the first time the mechanism behind the characteristic pattern of eruptive fissures on the island chain’s volcanoes.” Quoted from the USGS Newsroom.
“It rains more in the Northern Hemisphere because it’s warmer,” said corresponding author Dargan Frierson, a UW associate professor of atmospheric sciences. “The question is: What makes the Northern Hemisphere warmer? And we’ve found that it’s the ocean circulation.” Quoted from the University of Washington press release.
“Meteorologists often use information about warm and cold fronts to determine whether a tornado will occur in a particular area. Now, a University of Missouri researcher has found that the temperature of the Pacific Ocean could help scientists predict the type and location of tornado activity in the U.S.” Quoted from the University of Missouri press release.
“A magnitude 8.3 earthquake that struck deep beneath the Sea of Okhotsk on May 24, 2013, has left seismologists struggling to explain how it happened. At a depth of about 609 kilometers (378 miles), the intense pressure on the fault should inhibit the kind of rupture that took place.” Quoted from the University of California Santa Cruz press release.
The Spring 2013 issue of Oceanus Magazine, published by Woods Hole Oceanographic Institution, is titled Fukushima and the Ocean. It looks at the triple disaster that hit Japan with an earthquake, a tsunami and a power plant failure.
An interesting website is “Adrift” (Adrift.org.au). On this site you can click on a point in the ocean and a computer model will map the direction that floating debris would travel – both forward in time and backwards.
“Stanford scientists have identified key acoustic characteristics of the 2011 Japan earthquake that indicated it would cause a large tsunami. The technique could be applied worldwide to create an early warning system for massive tsunamis.” Quoted from the Stanford University press release.
Researchers have discovered evidence of life 500 meters below the seafloor of the Juan de Fuca Ridge. “They found genetic evidence of Methanosarcinales, anaerobic archaea known to metabolize methane. Further experiments showed that microbes have affected the chemical signature of sulfur in the host basalt, suggesting they could harness energy from the breakdown of sulfates.” Quoted from the Deep Carbon Observatory press release.
“Dynamic modeling of sea-level rise, which takes storm wind and wave action into account, paints a much graver picture for some low-lying Pacific islands under climate-change scenarios than the passive computer modeling used in earlier research.” Quote from the USGS press release.
Methane hydrate is the world’s largest natural gas resource. Japanese engineers recently became the first to produce methane hydrate from a well in the floor of the Pacific Ocean. NPR asks if this could become another natural gas boom?
A Magnitude 8.0 earthquake occurred in the Santa Cruz Islands area at about 8:12 PM EST. Tsunami warnings were issued for numerous islands in the South Pacific and waves up to 3 feet in amplitude have been reported.
USAToday reports that dozens of homes were damaged in the Solomon Islands.
CNN has an interview with Richard Ellis, author of “Search for the Giant Squid”, who explains the significance of a new video of a giant squid, filmed alive, 3,000 feet below the surface of the North Pacific ocean.
