NEW YORK, (CMC) -- A team of scientists from the United States has travelled to Grenada, exploring the darkest corners of a huge underwater volcano off the island’s coast hoping to better understanding the mysteries of earthquakes and tsunamis, and ultimately saving lives. President of US Ocean Exploration Trust, Robert Ballard, famous for discovering the Titanic 12,000 feet below the surface of the icy North Atlantic in 1985, has set his sights on exploring the volcano, ‘Kickem Jenny’, studying its eruption history and learn more about how underwater volcanoes can pose a threat. Ballard, who is also director of the Centre for Ocean Exploration at the University of Rhode Island’s Graduate School of Oceanography, said the Kickem Jenny volcano has a history of explosive eruptions, which could have the potential to trigger tsunamis, the effects from which could be felt as far away as the northeastern United States. According to the US Geological Survey (USGS), the Kickem Jenny volcano has erupted 10 times since 1939, with the most recent eruption in 1990. “This is the most hazardous part of our planet, where (tectonic) plates are head-on,” said Ballard, noting that the devastating 2011 Japanese earthquake and the 2004 Indian Ocean earthquake and tsunami were both underwater earthquakes. The American television network, ABC TV, said reporters from its ‘Nightline’ programme accompanied Ballard and his team of 40 explorers aboard their exploration vessel Nautilus during the final 48 hours of their 90-day voyage, which was documented for an upcoming National Geographic special, ‘Caribbeans Deadly Underworld’, which premieres Sunday on the US network, Nat Geo WILD. The conditions around the Kickem Jenny volcano are so dangerous to humans that Ballard and his team relied on the Remotely Operated Vehicle (ROV) ‘Hercules’, a 5,000-pound submersible, to be their “eyes and ears inside the volcano,” ABC TV reported. It said as Hercules descends into the volcano, Ballard and his team watch the robot’s live cameras from a control room aboard the Nautilus. After hours of searching, the team made a startling discovery. “It means that places that we thought there was very little life existing on our plant, we’ve just opened up a whole other area where life seems to be thriving,” Ballard said, adding “a lot of the deep sea is sort of like you know you can think of it as a desert. We just found an oasis in that desert.” More at link! jamaicaobserver/latestnews/US-scientists-explore-Grenada-s-huge-underwater-volcano
