Please consider submitting an abstract to the session Advances in Geophysical Sensing at the 2022 Annual Meeting of the Seismological Society of America which will be held in Bellevue, WA from April 19-23.  

Abstracts are due by January 12 at https://meetings.seismosoc.org/submit/    

A description of the session follows below


Seismological studies depend on the capability to measure ground motion resulting from the passage of seismic waves. Similarly, geodetic studies of tectonic and volcanic deformation are underpinned by measurements of changes in the shape of the Earth. Advances in observational geophysics rely on improvements in the quality of measurements and innovations that extend the types and ranges of phenomena observed. These advances both drive and are driven by development of theoretical and computational approaches to interpret observations. Recent years have seen considerable efforts to improve the quality of geophysical sensing. New techniques have been developed that complement established approaches by measuring new quantities and improving the quality and density of observations. Existing sensing techniques have been improved by reducing instrument self-noise, expanding bandwidth, improving calibrations for sensitivity and drift and developing compact and rugged instruments with lower power requirements for easier operation in the field. Dense multi-element networks in a variety of settings may use arrays of inexpensive sensors developed initially for consumer electronics purposes. There are often particular challenges to operating instruments in hostile locations such as the oceans, polar regions, volcanoes, other planets or very remote sites on Earth that have spurred technical advances. Methods of removing environmental noise from observations have been critical to improving geophysical observations, particularly within the oceans, but atmospheric and hydrological noise can also be important.

This session will provide an opportunity for scientists, engineers and instrument developers to discuss recent advances in the full range of sensors and sensing techniques for seismology, geodesy and related fields and explore potential applications of emerging sensing capabilities and future scientific needs and challenges.
