Dr. Joseph MacInnis is a Canadian physician, author, underwater diver and aquanaut. He was born on March 2, 1937, in Barrie, Ontario.
He first learned to scuba dive in 1954, at 17.
He earned his MD from the University of Toronto and did his internship at the Toronto General Hospital. It was during his internship that he came across John McGean, a tunnel construction worker who came in suffering from decompression sickness. This was the beginning of his lifetime passion in diving medicine and studying the effects that undersea exploration has on their psyche and physiology. He transferred McGean to a pressure chamber in Buffalo, New York. The patient fully recovered.
Between 1970 to 1974, MacInnis led four major scientific diving expeditions to Resolute Bay 965 kilometres (600 miles) north of the Arctic Circle.
On the third expedition, MacInnis established the first polar dive station, “Sub-Igloo.” This led to the very first filming of Harp seals and Bowhead, Narwhal and Beluga whales.
His team also discovered the remains of the HMS Breadalbane in the Northwest Passage, at 104 meters beneath the surface. The British ship sunk in 1835, crushed by ice.
He was heavily involved in the 1985 exploration of the Titanic. In 1991 he co-led a team in the filming of the IMAX movie of the fated ship.
Dr. Joseph MacInnis has written 9 books covering his explorations.
