A collaborative project between linguistic historians and marine biologists has successfully used AI-driven neural mapping to decipher a series of 9th-century 'Grantha' script fragments recovered from the Nicobar Islands. The manuscripts contain lost Sanskrit treatises detailing the systematic observation of marine bioluminescence, or what the texts call 'Samudra-Jyoti'. The authors categorized different types of light emissions from plankton and jellyfish, linking them to specific lunar phases and seasonal wind shifts.
The text reveals that ancient Indian mariners used these light patterns as a biological navigation tool to identify reef edges and deep-water currents during night voyages. By correlating the 'ghost-fire' of the sea with the position of the stars, the manuscript outlines a sophisticated hybrid navigational system that predates many European maritime observations by several centuries. The discovery highlights the deep integration of natural sciences within ancient Indian nautical traditions.
