6 What does the result show (artefact or biology)? Do we have to much or to little information? Methods that compare? Do we enter new methodological arenas? Would it be possible to test explanation factors?

7 Barents Sea Ecosystem Resilience under global environmental change – January 2011 Multivariate analyses will include: (1)Elimination of species from fish and benthos dataset that do not contribute to results of multivariate analysis (using Greenacres method) for both abundance (A) and biomass data (B) (2)Procrustes analysis relating CCA models results for fish and benthos (A and B) (3)Multivariate analysis of benthos-fish relationships using ter Braak's co-correspondence analysis (a special case of co- inertia analysis, looks at the relationship between two sets of abundance or biomass data) (ter Braak and Schaffers 2004).

8 Barents Sea Ecosystem Resilience under global environmental change – January Cooperation Agreement between IMR and PINRO All exchanged data can be used for any purpose by researchers affiliated with the two institutions. They can be used by researchers from third party institutions only with written permission from both IMR and PINRO. In such cases IMR and PINRO may charge a fee for the work related to the preparation of the data for use by third party institutions and/or make demands on co-authorship of publications etc.
