This grid layer displays aeromagnetic anomaly data (in nT) for the state of Washington. The dataset used to create this grid layer was obtained through the GeoNet Magnetic Data Repository that was developed and maintained by the Pan American Center for Earth & Environmental Studies (PACES), but this service and database is no longer available. The data incorporated into the GeoNet magnetic database was derived from the North American Magnetic Map (Open-File Report 02-414) compiled by the U.S. Geological Survey (USGS) in cooperation with the Geological Survey of Canada and Consejo de Recursos Minerales of Mexico. The original data for the state of Washington used for the North American Magnetic Map compilation came from numerous sources which can be found in USGS Open-File Report 98-241. Funding for this data compilation was provided through a U.S. Department of Energy geothermal grant.<\/SPAN><\/P><\/DIV><\/DIV><\/DIV>", "summary": "This layer provides a compiled and gridded magnetic dataset (in nT) for the state of Washington.
