Transits through the Dardanelles will be disrupted this until the weekend as Turkish authorities attempt to salvage a World War II submarine.
Vessel traffic will be one-way between 06:00 and 16:00 hours until Saturday, according to ship agency company GAC.
Salvors are reportedly looking to remove the wrecked ship Dumlupinar which lies at 90 metres off Nara Point, the narrowest and deepest point of the Dardanelles.
The submarine sank in a tragic accident off the coast of Turkey on 4 April 1953 following a joint NATO training exercise.
It reportedly collided with the Swedish vessel Naboland and sank. Ninety-four submariners died in the accident. Only two crewmembers survived.
The ship had been transferred to the Turkish Navy by the US Navy in 1950 under the mutual defence assistance program.
