Abstract

Marine dissolved organic matter (DOM) contains 662PgC, making it one of the largest exchangeable reservoirs of carbon on Earth. Understanding this pool requires assessment of its global distribution, its net production and export, and its fate.  Global surveys and process studies have illuminated the existence of several fractions of DOM, each with a specific role in the carbon cycle, ranging from daily support of microbial production to a possible role in hyperthermals of past climates.  This talk will highlight these behaviors of DOM, particularly its roles in the carbon cycle, and important uncertainties.
