摘要：The former British clipper Thermopylae built in Aberdeen in 1868 was later
renamed Pedro Nunes and sunk in 1907 during a naval exercise off Cascais, Portugal, in the
vicinity of the Tagus river estuary. Known to local fishermen, the wreck remains were formally
identified almost one century after the sinking and soon integrated within the network
of local heritage accessible to the (diving) public. A recent mission promoted by Cascais
municipality did enhance the technical, physical and cultural parameters attached to the
shipwreck remains which appear to be at the core of the history of oceanography and fishery
management in Portugal, fusing in the process a transdisciplinary approach in which the
archaeology of the physical remains fits into the physical and cultural identity of this estuarine
region.
