Off the coast of northern Israel, archaeologists have found ancient relics in the seabed where a gas pipeline is being built.But tapping into the undersea natural gas field known as leviathan is not without controversy.Environmentalists and local residents worry thousands of years of treasures may be lost during the undersea construction project.NewsHour Weekend Correspondent Megan Thompson has the story.In the waters off the coast of northern Israel near the ancient port city of Dor,a team of divers has discovered earthenware jugs, anchors and the remains of wrecked ships;some dating to the time of Phoenician and Roman sea trade.The marine archaeology unit of the Israel antiquities authority is working with the pipeline's developerwhich financed most of the research and recovery.We work very closely with the antiquities authority here in Israelto make sure that should we discover such finds we first of all avoid causing harm to those areas.Noble Energy says its project will not harm the environment.But some local environmentalists and residents oppose the planned offshore platformand pipeline and worry about what other treasures may be lost.There is no way that you can check all the hundreds of kilometers of pipeline.We know only that for a thousand years, 5,000 years, shipwrecks are laying out here.Here in the site of a football field we found already 28, so who knows how many more under this region.Protesters near the popular coastal area continue to object to the gas pipeline which is Israel's largest energy project.
