    Resumen

    CEMP data from different sites in Area 48 were used to compare patterns of inter-annual variability as a function of the site location to examine the spatial scale over which CEMP data that have been collected at an individual site reflect changes in the marine ecosystem. Correlations between combined standardised indices (CSI) of summer CEMP parameters were generally positive and the patterns of inter-annual variability of sites in Subreas 48.1 showed an increased level of concordance in the period since 2008. Further expert review of the CSIs from individual sites would be helpful in further clarifying the appropriate spatial scale monitoring data collected as part of CEMP.
