The oceans and climate are changing as a consequence of anthropogenic activities. Paleoceanographic information is pivotal to better assess future consequences of these changes on time-scales exceeding the length of the observational record. For example, paleoceanograhic data are crucial to determine whether oceanic feedbacks (biological, geological, oceanographic) will amplify or reduce oceanic CO2 sequestration or how large-scale changes in ocean circulation effect rainfall patterns on land.
This session will focus on paleoceanographic constraints used to improve future projections of climate change or to detect anthropogenic effects in the ocean exceeding the range of natural background variability. Contributions are invited on reconstructions and numerical modeling of past changes in physical, chemical, biological and sedimentary processes in the ocean, which have direct implications for the future state of the ocean.
