During a 19 days cruise in the Sea of Marmara we obtained:
We have established a data base of very accurate sea-bottom topography and shallow subbottom profiles over key portions of the Marmara Sea, including the Izmit Gulf, the continental shelf between Büyükçekmece and Bakirkoy, the shelf between the Prince Islands and Tuzla, the shelf East of the Imrali I. to Armutlu Peninsula, and the shelf and slope off Gaziköy that were ruptured by the 1912 earthquake.
No problem have to be reported about people and environment.
