Geologic Structure at the Bottom of the World: Highlights from Antarctic Seismology
Dr. Samantha Hansen, University of Alabama

ABSTRACT

Over the past decade, polar seismology in Antarctica has been advanced by a number of large-scale broadband seismic deployments, including the Transantarctic Mountains Seismic Experiment (TAMSEIS), the Gamburtsev Antarctic Mountains Seismic Experiment (GAMSEIS), and the Polar Earth Observing Network (POLENET). The logistics associated with working in such an extreme environment are quite challenging, but data from these different networks have greatly improved our knowledge about Antarctica's geologic structure and tectonic development. This presentation will focus on the unique working conditions in Antarctica and will highlight results from a number of seismic investigations with contributions from collaborators at the Washington University in St. Louis, New Mexico Tech, and the Pennsylvania State University. Future directions for Antarctic seismology and details about upcoming field deployments will also be shared.
