In 1963, a military icebreaker in the Southern Ocean spotted a curious smear across the tall walls of a huge Antarctic iceberg. Was it a plane crash? An underground base? What had the USS Edisto found? Secrets in the Ice is a brand new factual series that goes to the most remote, cold and inhospitable places on the planet to reveal great mysteries that were once frozen in time. Merging CGI recreations, advanced scanning technology and scientific research, the series investigates the curiosities that have been lost for millennia, or never seen before. This series explores how and why they ended up in the most desolate and distant corners of the planet and contemplates what mysteries might still be concealed in the frozen depths.
