Rivers discharge annually 248 teragrams (248,000,000,000,000 grams) of terrestrial dissolved organic carbon from the continents to the ocean. The majority of terrestrial dissolved organic carbon is recalcitrant against microbial mineralization in the ocean, but solar radiation can photochemically mineralize part of it into carbon dioxide.

An article published in the Global Biogeochemical Cycles on 20th of February 2018 estimates that solar radiation mineralizes 45 teragrams of terrestrial dissolved organic carbon in the...
