Marine archeologists are #inthefield in the Baltic Sea. This time they are at Tvärminne Zoological Station at 34 m of depth investigating a wooden wreck. The four person team from the Finnish Heritage Agency is being supported by volunteers whose help is irreplaceable in their work to discover the identity of the wreck. Some clues about the wreck are on display in Tvärminne in the form of artefacts found next to site. The investigation has been aided by the making of a 3D model prior to excavation work and making use of an underwater information system (UWIS) developed in Finland that helps with precise locations during dives. The Baltic Sea is littered with thousands of wooden ship wrecks, but very few are as well preserved as this beauty. Follow the work in Instagram #sunkenheritage_fin
