The Secretariat is the custodian of data which underpin the Commission's decisions and support the implementation and monitoring of those decisions. These data, collectively known as 'CCAMLR data', are used principally by CCAMLR's Scientific Committee, specialised groups and community of scientists, resource managers, fishery officers and policy makers. They include data from:

• fisheries in the Convention Area
• scientific observations on board fishing vessels
• research surveys and ecosystem monitoring
• compliance activities and processes
