Sedimentary rocks and unconsolidated sediments are ubiquitous features near the Earth’s surface. While they contain invaluable resources to our society, the sedimentary layer often obscures key features that are essential for understanding how the Earth works as a whole at depth.
For example, effects of this layer can simply manifest themselves as static corrections for travel-time tomography. However, in many cases, reverberations in this layer of low seismic speed overwhelm subtle signals upon which very popular techniques such as crustal receiver functions and other variants of receiver-side scattering rely.
In this SIG, we propose to invite a small number of speakers who have developed methods to alleviate this problem to give short presentations. The larger goal is to brainstorm other novel approaches not only to circumvent this problem but also to take advantage of properties of the sedimentary layer to build our signal or to explore properties of this layer that lies in the critical zone of societal concern.
