    Abstract

    This paper reports on available CEMP data and details of use as a guide for CEMP-related analyses, including an update on CEMP metadata available on the CCAMLR GIS and as hosted on the NASA Global Change Master Directory (GCMD). CEMP data submissions for the 2017/18 season are detailed by site and species, and a brief overview on general trends from the past three seasons by Subarea or Division has been included.

    The Combined Standardised Index (CSI) analysis has been updated from 2017 for Area 48 in order to compare patterns of inter-annual variability. Spatial analysis shows evidence of concordance of response to changes in the ecosystem between sites by Subarea, suggesting CEMP data are tracking similar processes. Further analysis to understand emerging trends and specific indices driving these patterns are required.
