  • Correlation of Seismic Data and Sediment Cores From the Seabed in the Medieval Harbour at Avaldsnes, Norway

    Open Access•Hallgjerd H Ravnås, Erik Daniel Fredh•ARTICLE•Geoarchaeology•2024•References: 1

    This interdisciplinary study demonstrates the successful integration of non‐destructive geophysical methods and sediment core analyses for mapping the seabed in the historical harbour at Avaldsnes in south‐west Norway. In the Medieval Period, this was a royal manor, with the harbour as a central hub for the Hanseatic League in the 14th to 15th centuries. The use of an Autonomous Surface Vehicle (ASV) mounted with two distinct sub‐bottom profiler …

  • Marine Geophysical Survey of a Medieval Shipwreck in Shallow Waters Using an Autonomous Surface Vehicle

    Open Access•Hallgjerd H Ravnås, Thomas Meldahl Olsen et al.•ARTICLE•Journal of Maritime Archaeology•2023•Cited by: 1•References: 6

    This study demonstrates the successful use of a single-channel chirp system mounted on an Autonomous Surface Vehicle (ASV) for detecting and mapping a partly buried medieval ship found in water approximately one meter (m) deep in a dynamic, intertidal environment at Avaldsnes, south-western Norway. The ASV's fast mobilization and access to areas otherwise difficult to reach, makes it an efficient, low-cost, and non-invasive platform for examining…
