This is the story of one man’s hobby and its overwhelmingly positive effect physically, emotionally, socially, and mentally on his life. The hobby is scuba diving, but not on the reefs of southern seas. This is about diving in Halifax Harbour. Diving summer and winter in one of the biggest and deepest harbours in the world has given Bob a view of history that few will ever witness.

Inquisitive and energetic, the author spins yarns about the strange and fascinating objects he finds and the hair-raising moments he has experienced, from coming to the surface and seeing the boat drifting out of sight to arriving on the surface in a snowstorm and having to navigate by compass to find the shore.

The bottom of Halifax Harbour has collected artifacts over the centuries from around the world. Each find gets picked up, cleaned, researched, and documented. The author’s database is a gold mine of little details about what arrived, eventually got dumped into the ocean, and is now sitting on display at home and in museums as a reminder of what once was.

The author takes the reader under warships, container ships, and tugboats, through huge docks, and under the ice. Along the way, he reflects on the toll that our civilization is taking on the ocean, of seagulls trying to break open golf balls to find food, of crabs trapped inside tires, and fish that take refuge in castoff bottles and grow too big to stay in but also too big to get out.
