Extreme climate and weather events shape the structure of biological systems and affect the biogeochemical functions and services they provide for society in a fundamental manner. There is overwhelming evidence that the frequency, duration, intensity, and timing of extreme events on land are changing under global warming, increasing the risk of severe, pervasive and in some cases irreversible impacts on natural and socio-economic systems. In contrast, we know very little how extreme events in the ocean, especially those associated with warming, acidification, deoxygenation and nutrient stress will unfold in time and space, as this requires dense observations and high-resolution ocean models. In addition, our understanding of the role of ocean extreme events for marine organisms and ecosystem services is very poor. This knowledge gap is of particular concern as the ocean provides food security and livelihoods for about 15% of the world population.I will move knowledge boundaries by discovering and attributing past and future changes in ocean extremes, and by assessing and mapping the risk of these ocean extreme events for marine organisms and ecosystems. I will quantify historical changes in marine heat waves and ocean acidification extreme events by synthesizing and analyzing novel satellite-based and in-situ physical and biogeochemical ocean observations. Model-derived relationships among physical and biogeochemical variables will be used to underpin the extreme event assessment of the sparse oxygen and net primary production observations. A new high-resolution global Earth System Model version will be applied to quantify and understand the drivers of past and future changes in ocean extreme events and to attribute specific ocean extreme events to human-caused climate change and natural variability. The integration of available and newly developed marine ecosystem exposure and vulnerability indices into the high-resolution modeling framework allows me to quantify regional risk levels of marine organisms and ecosystems to key ocean extreme events. This project aims at a major breakthrough in our understanding of the fundamental processes governing ocean extreme events and whether organisms and ecosystems might be pushed to the limits of their resilience and even beyond, potentially causing dramatic and irreversible changes.
