Climate variability directly constrains the ocean, sea ice dynamics and biogeochemical fluxes, which in return affect atmosphere and climate. The ocean modulates the intensity of climate change by absorbing and redistributing part of the heat excess and greenhouse gas increase resulting from human activities.
The processes driving the behaviour of the complex system of ocean dynamics / biogeochemical components / marine ecosystems are nonlinear and take place on large spatial and time-scale spectra, from thousands of kilometers (ocean basin) to several kilometers (fronts), down to centimeters (turbulence).
Interactions and feedbacks between the global ocean, climate change and human activities are numerous and complex. Improved description and prediction of climate change and of the fate of important elements (C, N, P, Si, O2, Fe, Mn, Cu, Zn) are required, in response to a strong societal demand. Research is also needed on alternative mitigation approaches ranging from the energy efficiency of maritime transport to strategies involving the management of marine ecosystems and the ocean carbon pump.
Indeed, climate modifications that have already begun and are foreseen for the next century imply major suitable political decisions and rapid changes in the organisation of society, including climate adaptation strategies.
To address these questions, the ISblue community has leading expertise in fine-scale ocean dynamics, observation of ocean circulation and global climate, distribution and global cycle of trace elements, process-based studies of the ocean carbon pump, evolution of sea state, sea ice and icebergs under climate change and their impacts on maritime transport, efficiency of marine shipping and mitigation politics.
ISblue Theme 1 is based on both disciplinary and interdisciplinary research, as well as on synergy between field studies, laboratory experiments, data analysis and innovative modeling.
Theme 1 will consider projects such as:
