|Caption=River export of N and P to coastal marine ecosystems for rivers discharging in the Arctic Ocean, Atlantic Ocean, Indian Ocean, Pacific Ocean and Mediterranean Sea and Black Sea for the 20th century. The IMAGE-GNM results for the 20th century show that the global river N export (19 to 37 Tg/yr, or +90%) increased faster than P export (2 to 4 Tg/yr or +75%). The increase in export by rivers draining into the Pacific Ocean (3.7 to 14.7 Tg N/yr, increase by a factor of 4; 0.6 to 1.6 Tg P yr-1, factor of 1.5) and Mediterranean Sea and Black Sea (0.9 to 2.1 Tg N/yr, +126%; 0.2 to 0.4 Tg P yr-1, +80% ) was much faster than in other parts of the world (Figure 5). The increase in P export was smaller than that of N in world regions. The differential increase of N and P explains the increase in the N:P ratio in rivers draining into the Pacific Ocean (13 to 20), Indian Ocean (14 to 18 since 1970), Mediterranean Sea and Black Sea (10 to 13). There was no clear increase in the regions draining into the Atlantic Ocean.

The IMAGE-GNM results show that the global river N export (+90%) increased faster than P export (+75%). The increase in export by rivers draining into the Pacific Oceanwas much faster than in other parts of the world. Reproduced from (Beusen et al., 2016)
