Description:
Parameters and initial values of a one-dimensional marine ecosystemmodel are optimized using a gradient-based optimization algorithm takinginto account parameter bounds. Sensitivities of the optimized parametersw.r.t. errors in observations and initial values are studied numerically andfound to yield parameter ranges narrow relative to the a priori parameteruncertainty reflected in upper and lower bounds on the permitted pa-rameter range. This means, that optimal parameters can be determinedaccurately. We find, that optimizing for the initial values along with theparameters can greatly improve the model’s fit to the observations
