Modelling the effect of physical variability on the midwater chlorophyll maximum
Abstract:A coupled model, employing turbulence closure physics and cell-quota threshold limitation biology, has been used to simulate the evolution of the vertical distribution of phytoplankton in a seasonally stratified shelf sea. Predictions are compared with observations from the North Sea. Variations in surface wind stress, which episodically weaken the thermocline barrier to nutrient input to the photic zone, are shown to make an important contribution to the formation of a midwater chlorophyll maximum in Summer.

More about this publication?
- The Journal of Marine Research publishes peer-reviewed research articles covering a broad array of topics in physical, biological and chemical oceanography. Articles that deal with processes, as well as those that report significant observations, are welcome. In the area of biology, studies involving coupling between ecological and physical processes are preferred over those that report systematics. Authors benefit from thorough reviews of their manuscripts, where an attempt is made to maximize clarity. The time between submission and publication is kept to a minimum; there is no page charge.
