As part of the October 29 Republic Day events, Ceylan and his team dove in Lake Van with instructors Serkan Ok and Zihni Aydın from the Van Diving School.
During the dive, they captured footage of the submerged ruins of a castle in the Adilcevaz district of Bitlis and the microbialites in the Edremit district of Van.
Ceylan and his team documented the water outflow from the microbialites and celebrated the Republic's anniversary by raising the Turkish flag deep in the waters of Lake Van.
