Approaches to the simplification of the summary and presentation of CEMP data

The current approach to providing advice on the status of the krill-centric ecosystem relies on the evaluation of statistical anomalies in the CEMP database. A new approach based on the ordination of variables according to functional groupings is suggested. This approach uses the methodology developed within WG EMM to produce composite standardised indices (CSIs) from matrices containing missing data to summarise the variability in CEMP parameters.
