U.S. Geological Survey geomagnetic variometer data: Capitalizing on seismic infrastructure U.S. Geological Survey geomagnetic variometer data: Capitalizing on seismic infrastructure
The U.S. Geological Survey’s Geomagnetism Program is collaborating with the Earthquake Hazards Program and Global Seismographic Network Program to densify magnetic field observations. This collaboration focuses on the installation of magnetometers, or magnetic variometers, at existing seismic stations. Along with improving the density of space weather observations for hazard monitoring...

Achieving sub-nanoTesla precision in multirotor UAV aeromagnetic surveys Achieving sub-nanoTesla precision in multirotor UAV aeromagnetic surveys
An uncrewed aerial vehicle (UAV) multirotor aeromagnetic system using a 5-m sling load for a magnetic sensor system is described and characterized. Four magnetic surveys with identical flight lines were completed, at two nominal altitudes of 25 and 40 m. The surveys were used to assess the repeatability of data collected with the described UAV aeromagnetic system, and comparison with a...

Magnetic field variations in Alaska: Recording space weather events on seismic stations in Alaska Magnetic field variations in Alaska: Recording space weather events on seismic stations in Alaska
Seismometers are highly sensitive instruments to not only ground motion but also many other nonseismic noise sources (e.g., temperature, pressure, and magnetic field variations). We show that the Alaska component of the Transportable Array is particularly susceptible to recording magnetic storms and other space weather events because the sensors used in this network are unshielded and...
