A revolutionary Strontium-90 dating methodology has been applied to submerged archaeological sites off the coast of Gujarat, achieving sub-decadal precision in chronometric mapping. By analyzing the uptake of strontium isotopes in marine-encrusted artifacts, researchers have successfully refined the timeline of post-Glacial maritime migrations in the Arabian Sea.
The study demonstrates that human communities were adapting to rising sea levels at a much faster rate than previously believed, constructing temporary settlements and navigation hubs as early as 10,000 BCE. This technique opens new possibilities for dating submerged heritage sites that are otherwise difficult to calibrate using traditional radiocarbon methods.
