Removal of dissolved inorganic carbon in the Yellow River Estuary
dissolved inorganic carbon Yellow River Estuary
2014/4/2
The Yellow River of China runs mainly through an arid and semiarid midlatitude region that has experienced
substantial anthropogenic and climatic change. This area includes the carbonate-rich Loess P...
The “salt wedge pump”: Convection-driven pore-water exchange as a source of dissolved organic and inorganic carbon and nitrogen to an estuary
salt wedge pump Convection-driven pore-water exchange source of dissolved organic inorganic carbon nitrogen to an estuary
2014/4/4
Hypoxia and anoxia in coastal waters have typically been explained by the respiration of sinking organic matter associated with nutrient over-enrichment and phytoplankton blooms. Here, we assess wheth...

The potentially toxic, diazotrophic filamentous cyanobacterium Cylindrospermopsis raciborskii has recently become a common component in the summer phytoplankton in the St. Johns River (SJR) estuary, F...
In situ fluxes of dissolved inorganic nitrogen from the sponge community on Conch Reef, Key Largo, Florida
dissolved inorganic nitrogen the sponge community Conch Reef, Key Largo, Florida
2014/4/21
We measured ammonium and nitrate plus nitrite fluxes from 14 common spongespecies on a Florida Keys reef (Conch Reef) using a combination of incubation experiments and an in situ method that requires ...

Analysis of the seawater CO2 system in the barrier reef-lagoon system of Palau using total alkalinity-dissolved inorganic carbon diagrams
the seawater CO2 system barrier reef-lagoon system total alkalinity-dissolved inorganic carbon diagrams
2014/5/4
We studied the seawater carbon dioxide (CO2) system in the Palau coral reef by measuring total alkalinity (TA) and total dissolved inorganic carbon (DIC). Variation in the CO2 system on the reef flat ...
