Modeling has been critical to the development and advancement of biogeochemistry. Models are... 

The models also assume a steady-state condition which suggests that the carbon cycle is structured, stable, and balanced and will remain so indefinitely. This mechanistic view of biogeochemistry allows for little variation even though it is known that fluctuations and variation occur seasonally. The concentration of...

The three dimensional multicompartmental chemistry transport model MPI-MCTM [Lammel et al (2001), Semeena and Lammel (2003), Gughelmo (2008)] was run for 40 years with a resolution of T21L19 in the atmosphere and GR30L40 in the ocean. The ocean biogeochemistry started from spin-up fields and the atmosphere from an initial run, necessitating a physical spin-up of 2 years prior to the actual simulation. Within a mn of 40 years the model produces its own climate based... 

I expand treatment of sorption, ion exchange, and surface complexation, in terms of the various descriptions in use today in environmental chemistry. And I integrate all the above with the principals of mass transport, to produce reactive transport models of the geochemistry and biogeochemistry of the Earth s shallow crust. As in the first edition, I try to juxtapose derivation of modeling principles with fully worked examples that illustrate how the principles can be applied in practice. 

Our ability to predict changes in the biogeochemistry of estuaries and lagoons, as well as other shallow water organic-rich environments, is tied to our ability to quantitatively model the dynamics of microbially-mediated energetic changes closely associated with degradation processes and their chemical end products.

Despite these application limitations, it nevertheless is true that chemical equilibrium models can generally provide reasonable approximations of many, but not all, real-world chemical processes. The better we understand the biogeochemistry of natural systems, the better we can adapt our geochemical models for specific systems. One need only peruse standard geochemical textbooks (e.g., Nordstrom and Munoz 1994 Drever 1997 Millero 2001) to sense the importance of such models in geochemical applications.
