On May 19, 2001, India's science and technology minister Murli Manohar Joshi announced the finding of the remains of an ancient city on the seabed of the Gulf of Cambay (also known as the Gulf of Khambat), along a nine kilometer stretch off the coast of Gujarat province. Located 40 metres deep it was discovered by the Indian National Institute of Ocean Technology in December 2000 and investigated for six months with acoustic techniques. The structures of the city were said to resemble those of major cities of the Indus Valley Civilisation, with regular geometric patterns representing a granary, a great bath and a citadel.

However some archaeologists reacted with skepticism. The institute that reported the results doesn't appear to have involved specialists in marine archaeology in the region and details were lacking. It was suggested that it could be a post-Indus city. They also pointed out that other nearby Indus settlements built on the coast were now well inland, the opposite to the geological change required to explain a sunken city. In any case the Indian technology minister is a controversial figure in archaeology.

A followup investigation was conducted by the same institute in November 2001, which included dredging to recover artifacts. News articles report that a block of wood was recovered that was dated to 9,500 years old, which is 5000 years older than the Indus Valley Civilisation. However claims that the Indus Valley Civilisation is thus 9,500 years old are probably premature.
