The purpose of this review is to highlight progress in unraveling carbon cycling dynamics
across the continuum of landscapes, inland waters, coastal oceans, and the atmosphere …

Understanding the dynamics of organic matter (OM) and the roles in global and local carbon
cycles is challenging to the fields of environmental sciences and biogeochemistry. The …

The deposition and long-term burial of organic carbon in marine sediments has played a key
role in controlling atmospheric O2 and CO2 concentrations over the past 500 million years …

Carbonate mineral weathering coupled with aquatic photosynthesis on the continents,
herein termed coupled carbonate weathering (CCW), represents a current atmospheric CO …

On shorter time scales, the karst carbon cycle coupled with photosynthesis, is a potential
carbon sink. The surface water biological carbon pump (BCP) plays an important role by …

Continental margin systems collectively receive and store vast amounts of organic carbon
(OC) derived from primary productivity both on land and in the ocean, thereby playing a …

The Deepwater Horizon (DWH) spill released 4.9 million barrels of oil into the Gulf of Mexico
(GoM) over 87 days. Sediment and water sampling efforts were concentrated SW of the …

Dissolved organic matter (DOM) in sediment pore water is a complex molecular mixture
reflecting various sources and biogeochemical processes. In order to constrain those …

The dissolved inorganic carbon (DIC) produced by carbonate weathering may be lost by
degassing or be biologically fixed as it transports from inland water to the ocean. Knowledge …

Organic carbon is important in regulating ecosystem function, and its source and abundance
may be altered by urbanization. We investigated shifts in organic carbon quantity and quality …
