Jeffrey J Love


I am a Research Geophysicist in the Geomagnetism Program of the U.S. Geological Survey (USGS). My research has encompassed a variety of subjects related to the Earth’s magnetic field. These days, I work in collaboration with colleagues on three subjects: 1. Using geomagnetic monitoring data and magnetotelluric survey data to evaluate geoelectric hazards of concern to the electric-power grid industry. 2. Statistical analysis of the rare occurrences of extremely intense magnetic storms. 3. Analysis of historical records of past space-weather events and their impacts.
