摘要

There is considerable interest in quantifying the air-sea exchange of CO_2 in coastal ecosystems. As repositories of terrestrial organic carbon that cannot be accounted for in sediment deposits, early researchers presumed that coastal waters were regions of significant CO_2 efflux to the atmosphere. However, recent global syntheses of direct estimates of CO_2 air-sea fluxes on continental shelves generally suggest that shelf waters are net sinks for atmospheric CO_2 globally (Cai et al., 2006; Borges et al., 2005), removing roughly 0.3 Pg C a~(-1), while nearshore and estuarine waters are generally a net source.
