Mathematical model of nutrient distribution in coastal waters [electronic resource]
An approach to biological modelling involving the use of separation transformation theory has been developed. By use of the theory, it is possible to reduce the number of independent variables in the system. The original four dimensional system (x, y, z, t) can be reduced to a vertical plane concept...

| 520 | 3 | |a An approach to biological modelling involving the use of separation transformation theory has been developed. By use of the theory, it is possible to reduce the number of independent variables in the system. The original four dimensional system (x, y, z, t) can be reduced to a vertical plane conceptual model by assuming along isobath homogeneity in the flow field as a partial function of the baroclinic flow field. Both temporally dependent and independent nitrate concentration equations are then obtained and solved by conventional approximation methods. This technique has applicability to ecological modelling and results obtained by its use show good agreement with field data. Parameterization of the physical processes shows horizontal diffusion and advection to be the important forces in the system. Scaling of biological dynamics show nutrient uptake by phytoplankton and detrital decomposition to be the most important biological factors in the system. This technique permits the testing of various hypotheses with a minimum amount of computer time. Applications in studies on the continental shelf processes affecting the oceanography of the South Atlantic Bight, with emphasis on nitrogen cycling in coastal waters of Onslow Bay, North Carolina, are described. | |
