Recent excavations at a newly identified Mature Harappan site near the Gulf of Khambhat have revealed a sophisticated Marine-Meteorology Hub designed to assist Indus Valley sailors navigating the Arabian Sea. The structure, a circular stone platform with a series of vertical slots, was found alongside four tapered stone vanes that archaeologists believe served as wind-direction indicators. This discovery suggests that the Indus Valley Civilization possessed advanced knowledge of monsoon patterns and utilized standardized instruments for maritime forecasting.
The facility is located adjacent to a massive stone-paved wharf, where researchers also recovered several etched carnelian beads and copper docking-hooks. According to lead archaeologist Dr. Rajesh Singh, the presence of a dedicated meteorological office indicates that the Harappans operated a centralized navigation authority to regulate trade voyages between the Indus Valley and Mesopotamia. This find redefines our understanding of Harappan maritime logistics and their technical mastery of environmental monitoring.
