A submarine approaches its naval base as a half sunken ship is seen near a shipyard on Salamina island, west of Athens, on Tuesday, Feb. 12, 2020. Greece this year is commemorating one of the greatest naval battles in ancient history at Salamis, where the invading Persian navy suffered a heavy defeat 2,500 years ago. But before the celebrations can start in earnest, authorities and private donors are leaning into a massive decluttering operation. They are clearing the coastline of dozens of sunken and partially sunken cargo ships, sailboats and other abandoned vessels. (AP Photo/Thanassis Stavrakis)
