Dr. Joe MacInnis, a physician and underwater researcher, discusses the recent advances in underwater research at a Nipissing University lecture. MacInnis begins with the discovery of the shipwrecks: the Titanic and the Atocha, and follows with the main part of the lecture, the discovery accomplished by his own team of Breadalbane shipwreck. Included are: a brief history of the ship, the efforts that went into the discovery, the difficulties of Arctic exploration as well as the benefits of cold water related to the state of preservation of the ship, and scientific discoveries that result from this type of expedition. The later part of the lecture explores new aspects of undersea research and future expeditions planned for Bermuda and the Canadian Great Lakes.

The collection consists of audio, video and film recordings made by Dr. Joe MacInnis and his team during his underwater dives from the 1970s to 2004. The bulk of the collection concerns the shipwrecks of the Titanic, the Breadalbane and the Edmund Fitzgerald. There are also many films that highlight deep sea ecology and oceanography, particularly hydrothermal vents and deep sea sharks. Most recordings in the collection consist of rough or unedited footage. The collection also includes television and radio programs on which Dr. MacInnis appeared and some video and audio recordings by MacInnis' friends and colleagues. There is a small selection of footage collected by MacInnis for research purposes, including footage of William Beebe and Otis Barton's deep sea dives in their revolutionary 'bathysphere' in 1934.
