Ocean-Earth Systems Theme
At IMAS we seek a deeper understanding of the interplays of processes and feedback loops among Earth's systems components (the biosphere, geosphere, hydrosphere, cryosphere, and atmosphere). We do this through observations and modelling, recognising the importance of unravelling some of the most complex
scientific challenges of our time, including:
- global climate change;
- ice shelf-ocean interactions
- natural hazards such as earthquakes, tsunamis, and volcanoes;
- non- renewable and renewable resource identification;
- ecosystem and geohazard characterisation;
- and anthropogenic noise in the ocean.
Further, in understanding the timing and impacts of past natural environmental changes will provide a factual baseline for preparing for future predicted changes. IMAS and our collaborating partners can contribute to the palaeoenvironmental story through research on ice cores, deep-sea sediment cores,
tree rings, and coral records.
