Marine Biogeochemistry

Research Activities

 

 Model development and improvement

 


  • development and improvement of biogeochemical models that are commonly applied in global simulations, such as the classical NPZD type model (nutrient-phytoplankton-zooplankton-detritus).

  • development of new modelling concepts (e.g. optimality-based models), and

  • improvement of representations of the interaction of marine biogeochemistry and ecology with the physical environment.

     

Assessment and calibration

of biogeochemical models in the local and global context under present, past and likely future conditions in order to improve reliability and uncertainty estimates of model simulations.

 

Application of the models

to study the role and sensitivity of marine biogeochemistry and ecology global change using our knowledge and tools (see research activities  and ).
