Concurrent Session 2: S10: Climate impacts on marine system structure and function: molecules to ecosystems


Chair: Alastair Hobday
The effects of anthropogenic global environmental change on biotic and abiotic processes have been reported in aquatic systems across the world. This global change has manifested in marine systems through altered oceanographic, biogeochemical and hydrological mechanisms that regulate marine system structure and functioning at different spatial and biological scales. Complex synergies between concurrent environmental stressors and the resilience of the system variables to trophic cascades, which vary in space and time, determine the capacity for marine systems to maintain structure and functioning with global environmental change. Consequently, to effectively understand, quantify and predict climate impacts on marine systems, an interdisciplinary approach that facilitates the exchange of knowledge and the development of new methods across spatial and biological scales is required. The objective of this session is to integrate scientific knowledge of climate-induced change on the functioning of marine systems through the presentation of innovative research findings and technologies across multiple spatial and biological scales. Presentations are invited on novel approaches and recent advances in methods that utilise extensive datasets at different spatial and biological scales to further process-based understanding of marine system functioning in a globally changing environment. A special issue of Marine and Freshwater Research will be developed in association with this symposium.
