"abstract": "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 magnetic flux variations are stronger at higher latitudes. We also show that vertical\u2010component seismic records across Alaska are directly recording magnetic field variations between 40 and 800\u00a0s period as opposed to actual ground motion during geomagnetic events with sensitivities ranging from 0.004 to\u00a00.48\u2009\u2009(m/s2)/T0.48\u2009\u2009(m/s2)/T\u2060. These sensitivities were found on a day where the root mean square variation in the magnetic field was 225 nT. Using a method developed by\u00a0Forbriger (2007, his section 3.1), we show that improving vertical seismic resolution of an unshielded sensor by as much as 10\u00a0dB in the 100\u2013400\u00a0s period band using magnetic data from a collocated three\u2010component magnetometer is possible. However, due to large spatial variations in Earth\u2019s magnetic field, this methodology becomes increasingly ineffective as the distance between the seismometer and magnetometer increases (no more than 200\u00a0km separation). A potential solution to this issue may be to incorporate relatively low\u2010cost magnetometers as an additional environmental data stream at high\u2010latitude seismic stations. We demonstrate that the Bartington Mag\u2010690 sensors currently deployed at Global Seismographic Network sites are not only acceptable for performing corrections to seismic data, but are also capable of recording many magnetic field signals with similar signal\u2010to\u2010noise ratios, in the 20\u20131000\u00a0s period band, as the observatory grade magnetometers operated by the U.S. Geological Survey Geomagnetism Program. This approach would densify magnetic field observations and could also contribute to space weather monitoring by supplementing highly calibrated magnetometers with additional sensors.",
