Controls on DOC Export Through Time Along the Eastern Coast of the U.S.

The riverine transport of carbon is an important component of the net terrestrial and oceanic carbon cycles. However, the inclusion of riverine fluxes in local, regional and global carbon budgets is only performed at rough scales. As a preliminary step towards the development of a spatially explicit map of the lateral export of DOC from terrestrial landscapes to coastal margins, we investigated the controls on hydrology, DOC concentration and DOC flux along the eastern coast of the US. The effects of changes in temperature, precipitation, and land-cover on patterns of changing organic carbon concentrations across small and large watersheds within the US will be discussed.
