Coastal eutrophication and harmful algal blooms: importance of atmospheric deposition and groundwater 'new' nitrogen and other nutrient sources

摘要

Nitrogen-limited estuaries, shallow coastal waters, and contrinental shelf waters cover only 15/100 of the world's ocean area, but account for nearly half the global oceanic primary production. This disproportionality is partly attributed to accelerating and geographically expanding anthropogenic N loading and eutrophication. Among ac- celerating N inputs, atmospheric deposition (AD) (as wet- and dryfall) and groundwater (GW) discharge are of considerable and growing importance.
