Indonesia High Sea

The open waters south of the Bengal delta lie under the influence of the monsoon. Winds and surface currents reverse with the seasons, while fresh water carried from the Ganges and Brahmaputra spreads over the northern bay. Mariners timed journeys across these waters to the changing winds, linking Bengal’s river ports with the coasts of eastern India and Southeast Asia. Storms could make the passage dangerous, especially as the monsoon changed.
