The Tamil Nadu State Department of Archaeology will start an underwater survey off the Poompuhar-Nagapattinam coast in mid-September 2025.
The survey aims to investigate submerged remains and uncover Tamil Nadu’s maritime history.
The Experts from the Indian Maritime University, National Institute of Ocean Technology, and National Institute of Oceanography will assist in the study.
Previous surveys in the 1980s and early 2000s revealed underwater structures and shipwrecks in the region.
