Aeolian Research at the Interface of Sedimentary, Atmospheric, and Biological Processes
Session ID#: 77058
Session Description:
Aeolian processes are the most pervasive agents of change in our solar system. They are responsible for the shaping and reworking of diverse landscapes, the initiation, development, and demise of granular bedforms and bedrock landforms, and provide insight into the geologic, meteorologic, volcanic, tectonic, and/or climatic histories of a region. From small repeating ripples in sand to megayardangs tens of meters tall and kilometers long, signatures of aeolian activities span a wide range of spatial and temporal scales across planetary bodies. In this session, we will explore recent advances in this highly interdisciplinary field and welcome contributions that address any interaction between wind and the environment. These may include, but are not limited to the use of modelling, experimental work, remote sensing, or field studies to address aeolian processes on Earth, Mars, Titan, and beyond.
