Turkey's seismic research vessel, Barbaros Hayreddin Pasa will continue its activities in the Eastern Mediterranean until Nov. 9.
Turkey issued a Navtex (navigational telex) on Friday announcing an extension to the Barbaros Hayreddin Pasa's research activities with "Tanux-1" and "Apollo Moon" vessels.
Earlier, Turkey had announced that the ship would conduct research in the region until October. 18.
Navtex is a maritime communications system that allows ships to inform other vessels about their presence in an area, as well as other information.
Turkey has consistently opposed Greece's efforts to declare an exclusive economic zone based on small islands near Turkish shores, violating the interests of Turkey, the country with the longest coastline in the Mediterranean.
Ankara has also said energy resources near Cyprus must be shared fairly between the Turkish Republic of Northern Cyprus (TRNC) -- which has issued Turkish Petroleum a license -- and the Greek Cypriot administration of Southern Cyprus.
Turkish President Recep Tayyip Erdogan has said the only solution to the dispute was through dialogue and negotiation, urging Athens to respect Turkey's rights.
