The consideration of entire “Source to Sink" systems is one of the most recent and challenging advance in earth surface dynamics and sedimentary geology. To understand S2S systems it is necessary to promote and enhance sharing of knowledge and concepts between previously separated disciplines that are involved in the analysis of S2S systems. In particular, studying S2S systems implies knowledge and skills from (1) geomorphology, which focuses on the understanding of erosion processes driving landform evolution and sediment fluxes, (2) stratigraphy/sedimentology, which focuses on the nature of sedimentary deposits and their distribution in time and space, and (3) tectonics and structural geology, which set the dimensions, geometry and dynamics of source/transfer areas and sedimentary basins (the sink). Understanding S2S systems also involves other Geosciences disciplines such as paleoclimatology and geochemistry, because they allow quantifying the factors controlling S2S systems dynamics (climatic controls on erosion, solid vs solute fluxes, etc.). The sedimentary record captures Earth’s environmental evolution through interactions with humans. Developing innovative strategies for shaping a sustainable future and responsible growth requires a holistic understanding of Earth’s resources and our impact on the environment that can be informed by the sedimentary archives.
The aim of this general session is to invite contributions from all S2S-related research fields in order to foster connections around a central theme and kickstart the emergence of a European S2S research community. In addition, we propose to use this session to initiate discussion on developing a strategy for S2S training of early-stage researchers to enable them to address the sedimentary system from source to sink and inform them of potential career opportunities in both the academic and non-academic sectors. We welcome all S2S-related and environmental signal propagation contributions, and in particular those addressing 1) perennial S2S dynamics in response to long-term tectonic and climatic signals in deep time, 2) transient S2S dynamics in response to short-term signals and extreme events, 3) generic S2S models inspired by nature, 4) relationships and feedbacks between human and S2S systems, 5) global to regional scale source-to-sink systems and the economic benefits of thinking in this mindset, and 6) innovative S2S training in academia and industry.
