Major challenges confronting marine biogeochemical modeling

Substantial improvements are required in the current suite of numerical models if we are to better understand the present ocean biogeochemical state and predict potential future responses to anthropogenic perturbations. At present, major impediments to marine biogeochemical modeling include the inadequate representation of multi-element cycling and community structure, large-scale physical circ...

Modeling Biogeochemical Processes in Marine Ecosystems

Modeling Biogeochemical Processes in Marine Ecosystems

Ecosystems are dynamic systems and the study of their functioning and evolution requires the development of dynamic biogeochemical models. A wide application and a pronounced development of this type of model has taken place during the last two decades due essentially, to the development of computer technology, which has permitted the handling of very complex mathematical systems, and also to t...
