Sony and Intel’s Project Shiphunt team of young explorers, scientists and historians has returned to shore with news of its underwater discovery: shipwrecks of the schooner M.F. Merrick and the steel freighter Etruria, in deep water off of Presque Isle in Lake Huron. The project was completed with “much thanks to pings, processing and 3D,” according to one marine archaeologist. Current Media, the Peabody-and Emmy Award-winning independent television and online network founded in 2005, will air their adventure as the hour-long special, “Project Shiphunt,” on August 30th at 10 p.m. ET.
