Hidden in Plain Sight: Monitoring Shipwrecks in the Atlantic Waters of St. Augustine, Florida (2016)
DOCUMENT Citation Only P. Brendan Burke.

The preservation of submerged heritage in Northeast Florida benefits from poor diving conditions and a lack of awareness of submerged site locations in the region. Overshadowed by the well-known treasure wrecks along Florida’s Treasure Coast and the Florida Keys, the northeastern portion of the state still maintains some of the oldest shipwrecks in North America. As part of the First Coast Maritime Archaeology Project, archaeologists from the Lighthouse Archaeological Maritime Program, the...

Survey for stone wall fish weirs on the continental shelf near Haida Gwaii, British Columbia using an Autonomous Underwater Vehicle (AUV). (2015)
DOCUMENT Citation Only Quentin Mackie. Alison Proctor. Fedje Daryl. Bradley Colin.

The search for early human occupation on drowned continental shelves is hampered by the low archaeological visibility of typical hunter-gatherer sites. Predictive modelling for site locations can produce polygons of potential, but these need to be tested both to evaluate the model and to recover material remains. Sampling of underwater predictive model potential polygons is difficult, expensive and usually low-return. However, some sites, such as stone-wall fish weirs, may be directly visible to...
