Dynamics of plankton growth in the Barents Sea: model studies
1-D and 3-D models of plankton production in the Barents Sea are described and a few simulations presented. The 1-D model has two compartments for phytoplankton (diatoms and P. pouchelii), three for limiting nutrients (nitrate, ammonia and silicic acid), and one compartment called “sinking phytoplan...
