Seafloor mapping XPRIZE final will be in the Mediterranean, off Greek coast

Seafloor mapping XPRIZE final will be in the Mediterranean, off Greek coast

Science
The final of the ocean XPRIZE, which will see fleets of robots compete to map the largest area of seafloor inside 24 hours, will take place in deep waters off the coast of Greece. Teams will be invited in turn to showcase their technologies, starting in early November. They will have to chart at least 250 sq km at depths down to 4,000m, and image 10 items of interest. The group that comes out on top will win $ 4m. Second place earns $ 1m. The Shell Ocean Discovery XPRIZE was launched in 2015 to find systems and approaches that could finally map the world's ocean basins to an acceptable precision. Currently, less than 15% of their bathymetry (depth) has been measured in a meaningfully accurate way. It is one of those truisms that ...
Tree rings helped scientists date ancient Greek eruption

Tree rings helped scientists date ancient Greek eruption

Science
Aug. 17 (UPI) -- Tree ring analysis has helped scientists pinpoint the date of Thera's eruption. The volcano on the Greek island of Santorini erupted sometime during the 15th or 16th century BC, but scientists have previously been frustrated by discrepancies between radiocarbon and archaeological evidence of the ancient eruption's precise timing. "It's about tying together a timeline of ancient Egypt, Greece, Turkey and the rest of the Mediterranean at this critical point in the ancient world -- that's what dating Thera can do," Charlotte Pearson, an assistant professor of dendrochronology at the University of Arizona, said in a news release. The latest findings, analysis of carbon in tree rings traced to the time of the eruption, have revealed an agreement, or overlap, between the timeli...

Magnitude-6.3 earthquake strikes eastern Turkey, Greek island

World
June 12 (UPI) -- A magnitude-6.3 earthquake struck western Turkey and the Greek island of Lesbos on Monday afternoon.The epicenter was at a depth of 4 miles in the Aegean Sea, 3 miles south of the Greek town of Plomari, on Lesbos island, the U.S. Geological Survey reported. It struck at 3:28 p.m.The BBC reported tremors were felt in Istanbul and Athens.In Plomari and nearby Mytilene, there were reports of several buildings damaged, roads closed and minor injuries but no casualties."We are advising residents in affected areas of Lesbos to remain outdoors until buildings can be inspected," senior seismologist Efthimios Lekkas said to the Standard.Turkey's emergency management agency said no casualties were reported."We will be seeing the aftershocks of this in the coming hours, days and week...
