Sediment transport mediated by cryogenic and biological processes (e.g., ice rafting, perennial ice cover, cryoconite formation, biofilm sloughing, and floating algal mats) can produce unique sedimentary features and significantly contribute to the sediment budget of depositional environments. Some of these processes are poorly understood, often going unrecognized in sedimentological studies, limiting our understanding of their contribution to the sedimentary record, and their application as environmental proxies.  In this interdisciplinary session we present novel approaches and new data characterizing these seemingly exotic, but actually common modes of sediment transport, with implications for hydrology, water quality, and paleoclimate, on Earth and beyond. We welcome submissions investigating sedimentary transport on all spatial and temporal scales and ecosystems, including work characterizing ancient and modern sedimentary features, in-situ observation, remote sensing, laboratory-based experiments, modeling and analog research to inform terrestrial and planetary exploration.
