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...

Insights Into Evolution Of Marine Life Provided By Genetic Patterns Of Deep-Sea Coral
2012-10-23 20:52:27

Patterns Also Shed Light on How Environmental Disturbances Affect Aquatic Organisms The ability of deep-sea corals to harbor a broad array of marine life, including commercially important fish species, make these habitat-forming organisms of immediate interest to conservationists, managers, and scientists. Understanding and protecting corals requires knowledge of the historical processes that have shaped their biodiversity and biogeography. While little is known about these processes,...

Scientists Set Out On New 45-Day Deep-Sea Expedition
2011-11-07 12:43:57

Scientists set out on an expedition to explore the depths of the Indian Ocean on Monday from Cape Town. The researchers will embark on a 45-day research cruise exploring areas where the deepest sea creatures lie. Aurelie Spadone, a sea specialist with the International Union for Conservation of Nature (IUCN) who is among the scientists, said "it would be very surprising if we don't come back with a new species." The mission is the second to visit the seamounts along the South-West...

  Officials from the National Science Foundation (NSF) are currently streaming live video from an undersea volcano, located off the coast of Oregon, which erupted back in April. The video feed is part of the NSF's Ocean Observatories Initiative (OOI) and is being overseen by Oregon State University geologist William Chadwick and his colleagues. The OSU and University of Washington scientists and engineers involved on the project are currently conducting site surveys onboard the...

US scientists from Oregon and New York, who have been monitoring the Axial Seamount, an undersea volcano located 250 miles off the Oregon coast, said on Tuesday that they have successfully predicted an eruption for the first time. The team of scientists forecast the eruption beginning about five years ago, predicting the volcano, which last erupted in 1998, would erupt again sometime before 2014. This marks the first successful prediction of eruption of an undersea volcano. During an...

Census of Marine Life reports in anthropogenic impact on deep sea The oceans cover 71% of our planet, with over half with a depth greater than 3000 m. Although our knowledge is still very limited, we know that the deep ocean contains a diversity of habitats and ecosystems, supports high biodiversity, and harbors important biological and mineral resources. Human activities are, however increasingly affecting deep-sea habitats, resulting in the potential for biodiversity loss and, with this,...

Nearly half a mile of rock retrieved from beneath the seafloor is yielding new clues about how underwater volcanoes are created and whether the hotspots that led to their formation have moved over time. Geoscientists have just completed an expedition to a string of underwater volcanoes, or seamounts, in the Pacific Ocean known as the Louisville Seamount Trail. There they collected samples of sediments, basalt lava flows and other volcanic eruption materials to piece together the history of...

A new large species of squid has been discovered among several dozens of other types gathered during exploration of the Indian Ocean, the International Union for the Conservation of Nature (IUCN) said Monday. The 27-inch-long new species is part of the "chiroteuthid" family. It has light emitting organs that attract prey in the darkness thousands of feet deep along the craggy seabed, according to the IUCN. More than 7,000 samples of lifeforms were gathered during last year's Seamounts...

Special issue of Marine Ecology publishes seamount research to contribute to the Census of Marine Life They challenge the mountain ranges of the Alps, the Andes and the Himalayas in size yet surprisingly little is known about seamounts, the vast mountains hidden under the world's oceans. Now in a special issue of Marine Ecology scientists uncover the mystery of life on these submerged mountain ranges and reveal why these under studied ecosystems are under threat. The bathymetry of our oceans...

Scientists have for the first time estimated the physical footprint of human activities on the deep seafloor of the North East Atlantic. The findings published in the journal PLoS ONE reveal that the area disturbed by bottom trawling commercial fishing fleets exceeds the combined physical footprint of other major human activities considered. The deep seafloor covers approximately 60% of Earth's surface, but only a tiny fraction of it has been studied to date. Yet as technology advances and...
