Changes in our marine environment are underway with increasing temperature, ocean acidification and deoxygenation affecting marine ecosystems. Monitoring has become particularly important in order to detect and help predict change, and Australia’s Integrated Marine Observing System (IMOS) aims to address this need by providing the infrastructure to observe our oceans. As a marine observing system, IMOS has focused on building long-term time-series data, making all data openly available, thus ensuring IMOS observations are available for use by many stakeholders. The richness of these data streams has also enabled the creation of new initiatives of interest to the fish biology and fisheries community, such as:
In addition to IMOS-led initiatives, IMOS data has contributed to the validation of a diversity of ocean models, including the ETAS model, used to study marine heatwaves along the east coast of Tasmania.
This talk will illustrate how these initiatives are contributing to measuring and understanding changes which impact on Australian fish ecology.
