Carbon dioxide emission and carbon accumulation in coastal wetlands
Estuarine, Coastal and Shelf Science, 1983Abstract Direct measurements of CO 2 fluxes were made in salt, brackish and freshwater marshes and parallel adjacent open water areas in Barataria Basin, Louisiana. Vertical flux density was determined by monitoring the accumulation of CO 2 in aluminum chambers placed over the water or sediment surfaces.

Carbon accumulation in salt marsh soils
2021Carbon accumulation in salt marsh soils is a beneficial ecosystem service that occurs as a result of in-situ macrophyte production, slow decomposition, and deposition of allochthonous sediments. Variation in rates of carbon accumulation within and among salt marshes may be influenced by factors including tidal flooding dynamics and sediment ...

A Model for Inorganic Carbon Accumulation in Cyanobacteria
1987Cyanobacteria have a mechanism to transport exogenous inorganic carbon (Ci) and concentrate it internally [1–3]. Both CO2 and HCO 3 - are the species taken up by the cells and HCO3- is the species which arrives at the inner membrane surface, regardless of the species supplied [4]. The uptake of CO2 into internal Ci pool would be accompanied with a flux

Carbon accumulation through ecosystem recovery
Environmental Science & Policy, 2009A market has emerged for carbon sequestered through reforestation. The opportunity to restore ecosystems through this market rather than establish plantations is demonstrated by an Australian case study. In the state of Queensland there are vast areas that have been cleared relatively recently and could be restored to ecosystems with high resilience ...

Is carbon accumulating in the northern temperate zone?
Global Biogeochemical Cycles, 1993The current imbalance in the global carbon budget (“missing carbon”) is approximately 1.5 to 2.0 PgC/yr. The study by Tans et al. [1990], based on geographically based estimates of industrial emissions, atmospheric data, and a model of atmospheric transport, suggested that the missing carbon was accumulating in terrestrial ecosystems of the northern ...

Sediment and Carbon Accumulation on Continental Shelves1
2010Continental shelves are important regions for the cycling of sediment and nutrients, which are affected by sediment dynamic processes. In this contribution, the continental shelf sedimentation patterns formed during the Holocene period and the related processes are examined, the impact of sedimentary processes on carbon burial on the continental shelf ...

Inorganic Carbon Transport and Accumulation in Cyanobacteria
1990The cyanobacteria use ribulose bisphosphate carboxylase/oxygenase (RuBisCo) as the first enzyme of photosynthetic CO2 fixation (Codd and Marsden 1984; Tabita 1988). This enzyme uses CO2 as its substrate (Filmer and Cooper 1970) and does so with surprisingly poor efficiency (Andrews and Lorimer 1987). For example, the enzyme from cyanobacteria has a Km (
