Note: Measured by port TEU activity along oceanic ranges.
Since the 1980s, a significant rebalancing of the intensity of trade by ocean took place, particularly over containerized trade. As international trade taking place over the Pacific Ocean increased, the Atlantic Ocean experienced a relative decline of its share. While the Atlantic accounted for 46% of global trade activity in 1980, this share decreased by more than half to 21% in 2010. The share of the Indian Ocean doubled to 10%, but this figure does not account for the substantial traffic transiting along the Asia / Mediterranean / European trade route.
