In 1967 and 1968 the USGS, in partnership with NASA and the National Park Service, extracted rock core from 13 locations in Yellowstone National Park. Depths of the holes ranged from 215 ft to 1,088 ft and the total drilled footage was 6,802 ft. The deepest hole was drilled in Norris Basin. Research on these cores provided critical understanding of complex geothermal systems that would inform the potential development of other systems, external to the park, as energy sources. These cores are extremely rare due to the many restrictions on sampling in the park. Years later, the cores were used to investigate the origin of some of Yellowstone supervolcano’s lavas using techniques that did not even exist when the cores...

This data collection includes ground-penetrating radar (GPR) data and related observations collected from the NASA Goddard Instrument Field Team (GIFT) Expedition to the Icelandic Highlands in July-August 2019 and August 2021. This dataset includes observations at the Askja Volcano and caldera and Vikrahraun lava flow. GPR data were collected using Geophysical Survey Systems, Inc (GSSI) shielded bistatic antennas at center frequencies of 200 MHz, 400 MHz, and 900 MHz. Common offset surveys were conducted to investigate the subsurface interfaces. The GPR data includes raw data obtained from the instrument (as GSSI .dzt files), line shapefiles of survey locations, and interpreted ice thickness GeoPackage files with...
