New Moor

South Talpatti (Bengali: দক্ষিণ তালপট্টি, romanized: Dokkhin Talpotti), also known as New Moore (Bengali: নতুন মুর, romanized: Nothun Moor) and Purbasha Island (Bengali: পূর্বাশা দ্বীপ), was a small uninhabited offshore sandbar island in the Bay of Bengal, off the coast of the Ganges-Brahmaputra delta region. It emerged in the Bay of Bengal in the aftermath of the Bhola cyclone in November 1970, and disappeared around March 2010.

Although the island was uninhabited and there were no permanent settlements or stations located on it, both India and Bangladesh claimed sovereignty over. There has been speculation over the existence of oil and natural gas in the region. The issue of sovereignty was also a part of the larger dispute over the Radcliffe Award methodology of settling the maritime boundary between the two countries. The matter was resolved on 7 July 2014, when the Permanent Court of Arbitration (PCA) delivered a verdict in the "Bay of Bengal maritime boundary arbitration between Bangladesh and India" case.
