英文摘要 | Black carbon (BC) is a recalcitrant form of organic carbon (OC) produced by landscape fires. BC is an important component of the global carbon cycle because, compared to unburned biogenic OC, it is selectively conserved in terrestrial and oceanic pools. Here we show that the dissolved BC (DBC) content of dissolved OC (DOC) is twice greater in major (sub)tropical and high-latitude rivers than in major temperate rivers, with further significant differences between biomes. We estimate that rivers export 184 Tg DBC year(-1) globally and that, including particulate BC fluxes, total riverine export amounts to 43 +/- 15 Tg BC year(-1) (12 +/- 5% of the OC flux). While rivers export similar to 1% of the OC sequestered by terrestrial vegetation, our estimates suggest that 34 +/- 26% of the BC produced by landscape fires has an oceanic fate. Biogeochemical models require modification to account for the unique dynamics of BC and to predict the response of recalcitrant OC export to changing environmental conditions. |
