A Norwegian drillship has been scanning the sea floor for weeks -- and endangering dolphins, whales and even fish farms. The Norwegian exploration vessel "Northern Explorer" is collecting data about potential oil and gas fields using seismic air guns. They trigger loud explosions which can endanger the lives of marine animals. The Croatian government plans to award the first drilling permits in 2015. The government awarded the oil exploration contract without a tender -- and without consulting parliament or the public.
