State and Trends of Australia's Oceans

The Data behind the Report

The role of IMOS as a national research infrastructure is to build large datasets and long time series for use and reuse. The process to produce this report is designed to ensure that datasets and time series available within Australia are organised, analysed, and interpreted so that they can be used in relevant assessment and reporting processes as required. Making our datasets and time series ‘assessment ready’ is part of the IMOS strategy to plan for impact. This includes data collected by IMOS facilities as well as additional data contributed by partners through the Australian Ocean Data Network (AODN).
