A first-of-its-kind documentary series exploring the natural wonders of the Persian Gulf and the ecosystems it supports went on air on Tuesday on the state-owned TV Channel 3. The 14-part series, which includes never-before-seen footage of incredible marine biota in the Persian Gulf, airs every day at 6 p.m., Mehr News Agency reported. Every 40-minute episode explores a different topic relevant to the gulf’s environment. Iranian ecologists and documentary filmmakers began work on the project in 2010, using state-of-the-art equipment to film and document life in the depths of Iran’s southern waters, said the show’s producer Ali Abdipour. “We went to the deepest, darkest regions of the water and shot amazing, jaw-dropping footage,” he told the news agency. “At times, we found ourselves in dangerous situations whose footage will give the audience a jolt.” This is the first-ever documentary series of Iran’s marine environments.
