Preserving the National Geothermal Data System's Geothermal Features and Observations Dataset (AASG-GDS)

Zaffos, Andrew; Richard, Steven

The National Geothermal Data System (NGDS) is a distributed, interoperable network of data collected from state geological surveys across all fifty states and the nation’s leading academic geothermal centers (https://data.geothermaldata.org). The system houses a variety of geoscientific data ranging from text reports, geologic maps, photo imagery, well logs, chemical and mineral assays, and various other research products. Its flagship data product was a collection of structured tables describing geologic wells, other geologic sampling features, and associated observations (e.g., heat flow, aqueous chemistry). These data tables remain the most heavily requested NGDS product, but institutional, financial, and technical instability among NGDS and its partnered data contributors has made access to this dataset erratic in recent years. In response, the Arizona Geological Survey (AZGS) and the U.S. Geosciences Information Network (USGIN) partnered to repackage and republish these datasets in trusted scientific archives under the codename AASG-GDS.
