Discuss the significance of underwater archaeological explorations at sites like Dwarka and Poompuhar in reconstructing India's ancient maritime history.

UNESCO defines underwater cultural heritage as traces of human existence submerged for at least 100 years [2]. For India, whose coastal past survives largely in Puranic and Sangam literature, submerged sites like Dwarka and Poompuhar convert textual memory into datable material evidence.

Building a submerged evidence base

• ASI's Underwater Archaeology Wing (UAW) carried out offshore and onshore excavations at Dwarka (2005–07), recovering sculptures and stone anchors examined at low tide [1].
• Since 2001, explorations have covered Bangaram Island (Lakshadweep), Mahabalipuram, Loktak Lake and Elephanta Island [1]; work is currently active at Dwarka, Bet Dwarka, Mahabalipuram and Karaikal [3].

Reconstructing maritime history

• Stone anchors are typological proxies for ship size, rigging and route networks, corroborating literary traditions that otherwise rest on texts alone.
• Submerged port structures at Poompuhar and Mahabalipuram attest to Chola and Pallava coastal urbanism, extending India's Indian Ocean trade narrative beyond terrestrial mounds.
• Shipwrecks fix precise dates for maritime encounters: the Danish ship Oresund, wrecked off Karaikal in 1619 CE, is being surveyed under an ASI–National Museum of Denmark MoU — the UAW's first international collaboration [4].

A widening institutional ecosystem

• A federated model operates: ASI-UAW centrally, the Tamil Nadu State Department of Archaeology licensed at Poompuhar, and NIO's Marine Archaeology Centre at Bet Dwarka, Chhari and Gangata Bet [3].
• The UAW collaborates with the Indian Navy for technical and logistical support [1].

Constraints

• Funding remains modest — UAW's annual allocation stayed under ₹1 crore in both 2025-26 and 2026-27 [3].
• Turbidity, siltation and salvage pressure persist; UNESCO's 2001 Convention therefore prioritises in situ preservation over intrusive recovery [2].

Underwater archaeology thus supplies the missing coastal chapter of Indian history. Sustained funding, a dedicated legal regime for submerged sites and expanded Navy–NIO partnerships would let this evidence anchor India's civilizational and maritime self-understanding, echoing the "Vikas bhi, Virasat bhi" vision.
