Brazilian Researchers Discover New Species Of Labrisomidae Fish
2013-10-29 09:41:22

Plataforma SINC Researchers from Brazil have published data on a new species of fish in the Labrisomidae family on the Brazilian archipelago of Trindade and Martim Vaz in the Atlantic Ocean. It is an endemic species that can only be found in this group of islands due to how far it is from the coast. A team of Brazilian researchers have described for the first time a new species of labrisomid, the Hypleurochilus brasil, endemic to the Brazilian archipelago of Trindade and Martim Vaz,...

Improving Volcanic Ash Forecasts For Aviation Safety
2013-10-26 05:29:46

April Flowers for redOrbit.com - Your Universe Online Frequent travelers can agree that flight delays are all too familiar these days. NASA is looking into a potentially dangerous, though much less frequent, problem that has recently caused major disruptions in flight schedules: volcanic eruptions. Ash and tiny, jagged particles are expelled from explosive volcanic eruptions. These particulates can be blown thousands of miles away from their source and are dangerous to airplanes,...

Impact Crater On Mars Could Actually Be Supervolcano
2013-10-23 09:11:16

Lawrence LeBlond for redOrbit.com - Your Universe Online In a first-of-its-kind discovery, scientists from NASA and the Planetary Science Institute in Tucson, Arizona have identified what could be a supervolcano on a planet, other than Earth, in our Solar System. The supervolcano in question was discovered on Mars and was previously classified as an impact crater. But after further analysis of the area, scientists believe the basin is actually the remnant landscape of an ancient...

Antarctic Volcano Seamounts Present Many Riddles To Volcanologists
2013-10-18 05:20:11

April Flowers for redOrbit.com - Your Universe Online When you think of the Antarctic, images of snow, ice and glaciers are the usual associations. We forget that it is also a region of fire, dotted with volcanoes on the mainland and the surrounding islands. Some of these volcanoes are extinct and some are still active, such as the Marie Byrd Seamounts in the Amundsen Sea. Today, their summit plateaus are at depths of 7,800 - 5,200 feet, making them difficult to reach with conventional...

Ancient Syrians Chose Buying Local Instead Of Importing
2013-10-16 15:02:48

University of Sheffield An archaeologist at the University of Sheffield has found evidence that, contrary to a widely held theory, ancient Syrians made their stone tools locally instead of importing finished tools from Turkey. The discovery, newly published online in Journal of Archaeological Science, has implications for our understanding of how early cities developed in these regions and how the geographic origins of raw materials affect developing states. During the Early Bronze...

Scientists Look At Supervolcano Life Cycle In Whole New Way
2013-10-11 14:49:13

Lee Rannals for redOrbit.com - Your Universe Online Scientists say they've discovered a new way to look at the life cycle of a supervolcano at a Yellowstone hotspot. University of Oregon researchers said that crystals of zircon from the Snake River Plain helped to solidify evidence of "recycled" super-volcanic magma chambers. This Yellowstone hotspot creates a conveyor belt style of volcanism because of the southwest migration of the North American plate at about 0.8 to 1.6 inches...

Iceland's Basalt Pillars Formed By Slow Lava And Water
2013-10-09 15:55:39

Brett Smith for redOrbit.com - Your Universe Online Icelandic folk legend has it that the rocky pillars in the country’s Skaelingar Valley were projectiles fired into the ground by armies of warring trolls. However, a new study in Journal of Volcanology and Geothermal Research indicates that these hollow pillars of basalt were formed by a very slow lava flow oozing from Iceland's volcanoes and interacting with water. The researchers’ conclusion is unusual because the mixing of water...

Study Shows Extrusive Volcanism Formed Hawaiian Islands
2013-10-07 09:17:25

University of Hawaii ‑ SOEST A recent study by researchers at the University of Hawaii – Manoa (UHM) School of Ocean and Earth Science and Technology (SOEST) and the University of Rhode Island (URI) changes the understanding of how the Hawaiian Islands formed. Scientists have determined that it is the eruptions of lava on the surface, extrusion, which grow Hawaiian volcanoes, rather than internal emplacement of magma, as was previously thought. Before this work, most scientists...

Volcano Experts Identify Source Of Largest Eruption In Past 3,700 Years
2013-10-01 16:24:02

Brett Smith for redOrbit.com - Your Universe Online Vulcanologist have identified the source of the largest volcanic eruption in the last 3,700 years, which was said to have created a ‘Pompeii of the East,’ according to a newly published report in Proceedings of the National Academy of Sciences. Using a wide range of scientific techniques, the study researchers were able to identify the Samalas volcano in Indonesia as the source of a 1257 AD eruption that sent volcanic ash around...
