Global Carbon Budget - Ocean Accurate assessment of anthropogenic carbon dioxide (CO 2 ) emissions and their redistribution among the atmosphere, ocean, and terrestrial biosphere – the “global [...] . The oceans are therefore the most important net sink for anthropogenic CO 2 emissions. The ocean in the Global Carbon Budget Less than half of all CO 2 emissions remain in the atmosphere, the other [...] . The oceans are therefore the most important net sink for anthropogenic CO 2 emissions. Each year, we collect estimates of the ocean carbon sink from global ocean biogeochemistry models (GOBMs) and
