Salvage divers work underwater in a blinding darkness. In their cumbersome diving gear, these men have barely enough room to move around, while at the same time fighting the cold temperatures and fast currents. It is a dirty, unromantic and highly dangerous way of earning a living.Yet, these divers would not have traded their jobs for any other profession. From locating sunken boxcars to repairing concrete foundations for bridges, no task is too risky. Any underwater salvage or repair work becomes the job of these elite divers. Salvage divers must be carpenters, masons, riggers, hydraulic mechanics, ironworkers, welders, pile bucks and underwater engineers. They must be able to adapt all blueprints, tools and equipment to the harsh realities of the underwater environment.Harrison, Rebecca is the author of 'Deep, Dark and Dangerous On the Bottom With the Northwest Salvage Divers', published 2005 under ISBN 9781419625831 and ISBN 1419625837.
