4-4-4-4-4-4-4-4-4-4-4-4-4 From: Eva Eibl <eva.ps.eibl@xxxxxxxxxxx> Dear Colleagues, we kindly invite you to submit an abstract to the session S016 Observing Wave Field Gradients in Seismology â?? Applications, Instrumentation and Theory (see the session description below). Though this year AGU Fall meeting will be partly virtual and partly in person, our session will be fully virtual. Please note that the abstract submission deadline is 4 August at 23:59 EDT/03:59 +1 GMT. We welcome invited contributions from Yara Rossi (ETH Zurich) and Jack Muir (Caltech). Looking forward to your contributions Felix Bernauer, Eileen Marin, Eva P.S. Eibl and David Sollberger Session description: https://urldefense.com/v3/__https://agu.confex.com/agu/fm21/prelim.cgi/Session/121950__;!!IKRxdwAv5BmarQ!JBqrpK9xgSlbNxGM3XmzBOpKPczAxiiA0yxQ-qoCvsMXIrA4hR1_OSo4xsvIkmA$ <https://urldefense.com/v3/__https://agu.confex.com/agu/fm21/prelim.cgi/Session/121950__;!!IKRxdwAv5BmarQ!MJAyRW0QCW-yKd0IC8Rk1K0NzVCZgIWSdpv_poAD6Rvee-PfxuBRw2Fu-1KViGQ$> Recent advances in seismic instrumentation have made direct observation of the complete seismic wave field possible, including the spatial gradients of the wave field, rotation and strain. Collocated observations of translation, strain and rotation open new applications in various disciplines such as seismic exploration, volcanology, glaciology, ocean bottom seismology, earthquake engineering and planetary exploration as well as geodesy and gravitational wave detection. We invite contributions on any recent development in the fields of applications, instrumentation, and theory for observing seismic ground rotation, strain and translation. These may include - but are not restricted to -alternative technologies for seismometers (e.g., optical technologies), fiber-optic technologies, such as fiber-optic gyroscopes or distributed acoustic sensing, high-frequency GPS, and array based methods. We strongly encourage contributions on data analysis techniques, instrument performance testing and experimental field studies. 4-4-4-4-4-4-4-4-4-4-4-4-4 ------------------------------
