CEMP indices: 2007 update

The CCAMLR Ecosystem Monitoring Program (CEMP) uses indices derived from data on indicator species collected by standard methods in the three Integrated Study Regions of the Convention Area. Each year the Secretariat updates the standardised index values and provides a summary of trends and anomalies in these data. This report covers predator indices only. Data were submitted by 8 Members for 10 sites and 13 different CEMP parameters for the 2006/07 season. No data was submitted from Ross Island, however counts from aerial photographs are being undertaken. Data were collected from Esperanza Station, but were lost in a fire onboard the icebreaker Irizar. The development of an ordination method, with guidance from WG-EMM and consultation with experts, remains a main priority for future work.
