Tom Packer and Steve Gatto have been exploring and photographing offshore shipwrecks from Nantucket to Florida for 29 years, including 20 years of diving on the Andrea Doria. They both shoot still photographs and video cronicling history before it is lost forever to future generations, due to the corrosive action of the sea. Harold Moyers is a wreck diver and operator of the dive boat Big Mac. He is a veteran of deep wrecks from the Andrea Doria to the wrecks of the New York mudhole, and East Coast.
