Chemical Analyses: During the time shipwrecks spent underwater and later on under the sediment, some chemicals built up in their tissues. Especially when woods stocked up of the sulphur on harbor floors directly affects the conservation process in the future. For this reason sulphur levels of wood samples of all the ships are determined by analyses. Research Associate Gökçe Kılıç is working on these analyses as a Doctoral Dissertation Project.
C14 Dating: Only 4 of the 37 shipwrecks identified at the excavation area were found with their cargo. This situation makes it impossible for comparative dating method used in archaeology to date shipwrecks that they only have woods. For this reason, at least three samples of C14 the only way to determine the date that ships were built. The average of three samples taken from keel, frame and planks that forms base structure of the ships are used for dating. These analyses are realized by Oxford University, Oxford Radiocarbon Accelerator Unit (ORAU).
Determination of Wood Deterioration: Shipwreck woods are identified as “waterlogged” that they have been found in different states of deterioration. Deterioration state is related with the amount of water that wood soaked up. Determining the state of deterioration an important subject in identifying the molecular weight of the chemical which is used in conservation procedure made with analyses of samples taken from every member of the ship. These analyses are realized by Research Associate Namık Kılıç from Department of Conservation of Marine Achaeological Objects of Istanbul University.
