The Polish Maritime Museum in Gdansk participated in the EU project MACHU aiming at creation of a system of location, making information on European subaqueous maritime cultural heritage available and dissemination of it. 7 EU countries co-operated in the project. The Wood Technology Institute contributed to research on durability of small oak wood samples submerged in the sea. The samples were considered bioindicator of changes. The outline of research in the project is presented below.

Centralne Muzeum Morskie w Gdańsku uczestniczyło w projekcie UE MACHU zmierzającym do stworzenia systemu lokalizacji, udostępnienia i upowszechnienia informacji o europejskim podwodnym morskim dziedzictwie kulturowym. W projekcie współpracowało 7 krajów UE. Instytut Technologii Drewna wziął udział w pracach w zakresie badań trwałości w warunkach zatopienia w morzu małych próbek drewna dębu traktowanych jako bioindykator zmian. Przedstawiono zarys badań w projekcie.

The site was discovered in 1977 by amateur scuba divers. During preliminary excavation in the Puck Lagoon, a massive system of timber structures, fascine, and stone as well as earthen embankments scattered over an area of over 12 hectares, were found. Looking at the chronological arrangement of the site, slowly reconstructed on the basis of dendrochronological analyses and supplemented with radiological research, it should be assumed that the northern strip of the construction is a continuation of the quay strengthening construction, the root of a harbour pier. It is probably the earliest stage of the Puck harbour development. Taking both the layout of the construction, working as defences of the swampy alluvial estuary of the Płutnica river, parallel to the present coastline, as well as chronological layout of the stand, which gets younger and younger the closer it gets to the present shore line, it may be assumed that the changes in the location of the port construction were influenced by quite quick deepening of the basin and movement to the south of the medieval shore line.
