Abstract
WG-SAM-2021 and WG-EMM-2021 reviewed available information for krill assessment simulations in Subarea 48.1 using the Grym. Whilst no agreement on parameters was achieved at WG-SAM-2021, the Working Group agreed that an ensemble approach using multiple parameter value combinations could be used (WG-SAM-2021, paras 3.21-3.22.)
WG-EMM-2021 provided initial parameters for the assessment simulations noting that alternate parameters could be tested to compare (WG-EMM-2021, paras 2.32-2.33 and Table 1).
Here we present the results of model ensembles for values either provided directly to the CCAMLR e-group on ‘GYM/Grym assessment model development’, or calculated based upon data submitted to the e-group. Code and outputs of the models are available on github (https://github.com/ccamlr/Grym_Base_Case /tree/Simulations).
