Science gateways allow research communities to access shared data, software and services. GeoGateway ( is a science gateway that provides online tools for analysis, and modeling of crustal deformation using geodetic imaging data. GeoGateway bridges the gap between production and end-use of data products by simplifying the discovery of geodetic imaging products including UAVSAR, InSAR, GNSS, seismicity and fault data thereby enabling users to explore and integrate data products, and allowing researchers to easily share, publish and collaborate. We developed multiple methods for expanding the GeoGateway science user community. Initial efforts focused on showcasing GeoGat...eway in scientific talks, posters and papers. Discussions with users revealed technical challenges for adoption by novice users. To make GeoGateway accessible to a broad audience, we developed tutorial exercises and a GeoGateway User Guide. The tutorial exercises were tested in an undergraduate class at CalPoly Pomona in 2018, and the User Guide was rolled out during a workshop at the 2019 SSA Meeting. The classroom exercises and SSA workshop generated the largest single day user counts (41-42) to that date. Subsequently the 2019 Ridgecrest CA earthquake sequence generated the largest daily user count (55), suggesting that user training and development of a guide were effective in making GeoGateway more accessible to users following an earthquake. Since 2015 there were >11,000 GeoGateway sessions and >600 repeat users. In the past year there were >340 repeat users and >2,700 sessions. We are currently developing video tutorials to enhance the GeoGateway website, and offering webinars for remote training.
