Greenland Halibut SCAA Robustness Tests

This paper provides details of the full set of SCAA (Statistical Catch At Age) operating models intended for use in the MSE process for Greenland halibut. It first summarises the Reference Case operating model and the six variants thereof to serve as robustness tests, and then provides values of key associated parameter values and plots of estimated trends for various components of the biomass. Two Appendices list the data used for conditioning (fitting) these models and the complete mathematical specifications of the models and the (penalised) likelihood maximised in the fitting process.
