Come join Maritime Archaeologist Caleb O’Brien discuss two steel freighters in Thunder Bay National Marine Sanctuary: Norman and Grecian through the use of 3D models.

Caleb O’Brien is a Maritime Archaeologist at Thunder Bay National Marine Sanctuary who has spent the last two years researching two steel-hulled shipwrecks within the sanctuary. Norman and Grecian were built by Globe Iron Works in Cleveland, OH in the early 1890s and worked shipping iron between Escanaba, MI and Cleveland. By analyzing the historical record, archaeological data, and the builder’s plans, this presentation will show through 3D computer models how these ships changed during their working lives to the wrecks today. This presentation will allow visitors to experience and see what Great Lakes ships looked like in the 1890s and see what these two wrecks look like today!
