Seasonal Variability of Carbon Dioxide in the Rivers and Lagoons of Ivory Coast (West Africa) (2009)

Koné, Yéfanlan José-Mathieu, Abril, Gwenaël, Kouadio, K.N., Delille, Bruno, Borges, Alberto

We report partial pressure of CO2 (pCO2) and ancillary data in three rivers (Bia, Tanoé, and Comoé) and five lagoons (Tendo, Aby, Ebrié, Potou, and Grand-Lahou) in Ivory Coast (West Africa),...

The impact of lateral carbon fluxes on the European carbon balance (2008)

Ciais, P, Borges, Alberto, Abril, Gwenaël, Meybeck, M, Folberth, G, Hauglustaine, D, ...

To date, little is known about the impact of processes which cause lateral carbon fluxes over continents, and from continents to oceans on the CO2 – and carbon budgets at local, regional and...

Emission of CO2 and CH4 to the atmosphere by sediments and open waters in two Tanzanian mangrove forests (2008)

Kristensen, Erik, Flindt, Mogens R., Ulomi, Shadrack, Borges, Alberto, Abril, Gwenaël, Bouillon, Steven

Carbon gas balance was evaluated in an anthropogenically impacted (Mtoni) and a pristine (Ras Dege) mangrove forest in Tanzania. Exchange of carbon dioxide (CO2) was measured for inundated and...

Dynamics of organic and inorganic carbon across contiguous mangrove and seagrass systems (Gazi bay, Kenya) (2007)

Bouillon, Steven, Dehairs, Frank, Velimirov, Branko, Abril, Gwenaël, Borges, Alberto

We report on the water column biogeochemistry in adjacent mangrove and seagrass systems in Gazi Bay (Kenya), with a focus on assessing the sources and cycling of organic and inorganic carbon....

Importance of intertidal sediment processes and porewater exchange on the water column biogeochemistry in a pristine mangrove creek (Ras Dege, Tanzania) (2007)

Bouillon, Steven, Middelburg, Jack J., Dehairs, Frank, Borges, Alberto, Abril, Gwenaël, Flindt, Mogens R., ...

We sampled a tidal creek (Ras Dege, Tanzania) during a 24-h cycle to document the variations in a suite of creek water column characteristics and to determine the relative influence of tidal and...

Carbon dioxide in European coastal waters (2006)

Borges, Alberto, Schiettecatte, LS, Abril, Gwenaël, Delille, Bruno, Gazeau, Frédéric

We compiled from literature annually integrated air-water fluxes of carbon dioxide (CO2) computed from field measurements, in 20 coastal European environments that were gathered into 3 main...

Gas transfer velocities of CO2 in three European estuaries (Randers Fjord, Scheldt, and Thames) (2004)

Borges, Alberto, Delille, Bruno, Schiettecatte, Laure-Sophie, Gazeau, Frédéric, Abril, Gwenaël, Frankignoulle, Michel

We measured the flux of CO2 across the air-water interface using the floating chamber method in three European estuaries with contrasting physical characteristics (Randers Fjord, Scheldt, and...

Gas transfer velocities of CO2 in three European estuaries (Randers Fjord, Scheldt and Thames) (2004)

Borges, Alberto, Delille, Bruno, Schiettecatte, Laure-Sophie, Gazeau, Frédéric, Abril, Gwenaël, Frankignoulle, Michel

We measured the flux of CO2 across the air–water interface using the floating chamber method in three European estuaries with contrasting physical characteristics (Randers Fjord, Scheldt, and...

Carbonate dissolution in the turbid and eutrophic Loire estuary (2003)

Abril, Gwenaël, Etcheber, Henri, Delille, Bruno, Frankignoulle, Michel, Borges, Alberto

We measured particulate and dissolved organic carbon (POC and DOC), chlorophyll, oxygen, partial pressure of Co-2, pH, total alkalinity (TAlk) and particulate inorganic carbon (PIC) during a late...

Inorganic and organic carbon biogeochemistry in the Gautami Godavari estuary (Andhra Pradesh, India) during pre-monsoon : the local impact of extensive mangrove forests (2003)

Bouillon, Steven, Frankignoulle, Michel, Dehairs, Frank, Velimirov, Branko, Eiler, Alexander, Abril, Gwenaël, ...

[1] The distribution and sources of organic and inorganic carbon were studied in the Gautami Godavari estuary (Andhra Pradesh, India) and in a mangrove ecosystem in its delta during pre-monsoon. In...

Excess atmospheric carbon dioxide transported by rivers into the Scheldt Estuary (2000)

Abril, Gwenaël, Etcheber, Henri, Borges, Alberto, Frankignoulle, Michel

The transport of excess atmospheric CO2 (defined as the fraction of dissolved inorganic carbon (DIC) that can escape as CO2 to the atmosphere due to water-air equilibration), by the five rivers...

Carbon Dioxide Emission from European Estuaries (1998)

Frankignoulle, Michel, Abril, Gwenaël, Borges, Alberto, Bourge, Isabelle, Canon, Christine, Delille, Bruno, ...

The partial pressure of carbon dioxide (pCO2) in surface waters and related atmospheric exchanges were measured in nine European estuaries. Averaged fluxes over the entire estuaries are usually in...
