GAGE/SAGE 2021 Community Science Workshop

Revealing Earth Systems: Integrating Spatial and Temporal Data

This workshop stretches across disciplinary boundaries and focuses on elements that are common to the diverse disciplines and applications within the GAGE & SAGE communities. It highlights synergies between geodesy and seismology in time, space, and methods for approaching datasets and changes in the Earth System. It provides an opportunity to learn about cutting edge research, engage with other members of the community, and expand technical skills.

The workshop will be held virtually. Main days will be Tuesday-Thursday August 17-19, 2021. Short courses will be August 9-13 and a few other activities will be August 16 and 20.

This meeting is the equivalent of the UNAVCO and IRIS Science Workshops, which used to be held separately. The first joint workshop was held in Portland, Oregon in October 2019.

Sponsored by the the US National Science Foundation (NSF). The Geodetic Facility for the Advancement of Geoscience (GAGE) and the Seismological Facility for the Advancement of Geoscience (SAGE) are run by UNAVCO and IRIS, respectively, through cooperative agreements with NSF.

Plenary Sessions

Behavior at and coupling across key Earth interfaces

This session is aimed at understanding the structure and processes associated with interfaces and boundaries within the Earth system. Examples include the boundary between the solid Earth and its fluid envelopes, the boundary between the solid mantle and the liquid outer core, the land/ocean interface at continental margins, and Earth’s permeable near-surface boundary layer known as the critical zone. It will include contributions that highlight new data sets and observation strategies that target these interfaces, those that reveal new understanding of the processes operating at them, and studies that explore the ways that different regions of the Earth interact and how different components of the Earth system are coupled across interfaces.


Illuminating Transients in Earth Processes

This plenary session focuses on integrative studies of transient deformation and Earth structure. Recent advances in seismic and geodetic monitoring technologies and methods have revealed time-dependent deformation processes and changing constitutive properties in a wide variety of Earth systems. Examples include slow slip on plate-boundary faults, a range of postseismic deformation processes, seasonal and multi-year aquifer changes, and landslide dynamics. These time varying signals can be captured by various geodetic methods, continuous seismic imaging using ambient noise, receiver functions or active source experiments, and repeated electrical resistivity imaging. We seek contributions that combine multiple methods to illuminate transient deformation and changing mechanical properties in the Earth.


New approaches to processing big geophysical and geospatial datasets

“Big data” is challenging our computational capabilities in terms of volume, velocity and variety (3Vs). Increases in the spatial and temporal resolution of our geophysical observations have produced dramatic increases in the amount of data for geoscientists to analyze. Each stage of the life cycle of geospatial big data can present issues for our community: (1) data acquisition, (2) compilation and management, and (3) data analysis, visualization and distribution. This session seeks to showcase strategies that are overcoming these obstacles and providing new insights into Earth behavior. For instance, machine learning presents a host of new opportunities for our community, with increasing emphasis on technical rigor, common benchmarks, and repeatability. In addition, enhanced understanding can also be achieved via data amalgamation, high-performance computing, data mining, and dataset-integration strategies. Vast datasets also create opportunities for improved statistical characterization and improved quantification of uncertainties. We are particularly interested in highlighting techniques likely to be scalable and transferable to other problems.
