Note: Measured by port TEU activity along oceanic ranges.
Since the 1980s, a significant rebalancing of the intensity of trade by ocean has taken place, particularly over containerized trade. As the 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.
