Maritime Archaeology

Maritime archaeology investigates human interaction with the marine environment through study of submerged cultural remains. It employs underwater survey, remote sensing, geophysical prospection and detailed excavation to locate and document shipwrecks, ports and coastal sites. Advances in sonar and sub-bottom profiling now enable high-resolution mapping of buried structures, while satellite imagery and aerial photogrammetry illuminate changing shorelines and harbour topographies. Analytical tools such as dendrochronology, radiocarbon dating and isotopic analysis provide precise chronologies and provenance for timbers and artefacts. Geographical Information Systems and numerical modelling of wind, currents and vessel performance have refined reconstructions of ancient trade routes, voyage duration and seasonal navigation. Experimental archaeology, using replica vessels and sailing trials, tests hypotheses on hull design and rigging, revealing technological innovation across cultures. Conservation science has developed in situ stabilisation and controlled recovery protocols for fragile organic and metal artefacts. Conceptual frameworks such as seascape archaeology emphasise the maritime environment as a dynamic cultural space, linking coastal management, heritage preservation and climate resilience. Together, these approaches uncover networks of exchange, identity and adaptation that spanned the Bronze Age to the early modern period and inform contemporary responses to underwater cultural heritage threats.

Research from Nature Portfolio

Researchers have introduced a multi-criteria simulation of age-of-sail shipping corridors by integrating historical meteorological records with reconstructed ship performance. The method generates monthly routing predictions between key European and Mediterranean ports, yielding quantitative journey-time metrics and identifying persistent maritime corridors. Validation with archival voyage logs confirms its accuracy, offering new insights into trade intensity, seasonality and economic integration along pre-steam networks.

Geo-scientists have elucidated the Holocene evolution of an ancient lagoon that hosted the primary harbour of Pisa from circa 200 BC to the 5th century AD. Sequential sediment cores and relative sea-level reconstructions reveal a phase of stable lagoonal conditions during peak Roman use, followed by gradual infill and basin isolation from the 14th to 16th centuries. This work demonstrates how combined stratigraphic and bio-geochemical analyses resolve long-term coastal dynamics and human modification of harbour landscapes.

Technical terms

Multi-criteria simulation: A computational approach that integrates diverse environmental and performance factors to model optimal maritime routes.

Relative sea-level reconstruction: The process of reconstructing past sea levels by analysing stratigraphic and palaeoenvironmental proxies from sediment cores.

In situ preservation: Conservation strategy that stabilises archaeological materials within their original marine context to prevent deterioration prior to recovery.

Cartogram: A map in which spatial geometry is distorted to represent variables such as travel time or connectivity rather than true land area.

Seascape: The conceptual framework that treats the maritime environment as an interactive cultural and ecological domain.
