Present nitrogen and carbon dynamics in the Scheldt estuary using a novel 1-D model
nitrogen and carbon dynamics Scheldt estuary novel 1-D model
2010/1/18
A 1-D, pelagic, reactive-transport model of a completely mixed, turbid, heterotrophic estuary – the Scheldt estuary – is presented. The model resolves major carbon and nitrogen species and oxygen, as ...
Reconstruction of the biogeochemistry and ecology of photoautotrophs based on the nitrogen and carbon isotopic compositions of vanadyl porphyrins from Miocene siliceous sediments
Reconstruction biogeochemistry ecology photoautotrophs isotopic compositions

We determined both the nitrogen and carbon isotopic compositions of various vanadyl alkylporphyrins isolated from siliceous marine sediments of the Onnagawa Formation (middle Miocene, northeastern Jap...
Linking an economic model for European agriculture with a mechanistic model to estimate nitrogen and carbon losses from arable soils in Europe
economic model European agriculture mechanistic model nitrogen and carbon losses
