    dct:description "This dataset provides national scale location information for known, publicly available, data on helium gas concentrations, reported in mol%. The dataset was created as part of the effort by the United States Geological Survey (USGS) to conduct an assessment of helium resources in accordance with the Helium Stewardship Act of 2013, Public Law 113-40. The data were collected from the USGS Energy Geochemistry Database, Bureau of Land Management (BLM) databases, State geological survey databases, and a thorough review of the published literature. This dataset represents an aggregation of multiple datasets into one unified, cohesive system that has a number of attributes for use in a resource assessment and for dissemination to the public." ;
