Inspection visit to the wreck of the Vrouw Maria in 2009


An inspection visit to the Vrouw Maria was carried out regarding the protection and management of the wreck on 20 - 24 July 2009 using the Finnish Environment Institute's support vessel r/v Muikku. On the basis of photographs and video footage taken of the wreck, it was found that no visually observable changes had taken place to the condition of the wreck. To study the condition of timber structures on the wreck, a sample of oak was taken from the bow at deck level. The timber sample was studied and analysed by microbiologists and physicists at Helsinki University. Bacteria and fungus, etc. from the timber sample, which feed on timber, thus destroying the structure of the wreck, were studied. The research vessel r/v Muikku at the wreck of the Vrouw Maria.

During the inspection visit, samples were also taken of the sea bed by Monivesi Oy in order to study sediment organisms. The samples are linked to research into the prevailing environmental conditions at the wreck. If more extensive fieldwork is carried out at the wreck in the future, or if it is raised, fieldwork must be preceded by a Natura impact assessment examining the effect of the measures on the surrounding environment, including seabirds and seals. Samples were taken from the structural part raised on the inspection visit in the National Board of Antiquities’ Conservation Laboratory for waterlogged materials.
