Gem Infrasound Logger

About the Gem

The Gem is an all-in-one single-channel infrasound logging system that suitable for rapid deployments and large-N campaigns, and requires minimal training. It is optimized for low cost, low power consumption, high portability, and ease of installation/concealment.

The Gem project is run by Dr. Jake Anderson at the Infrasound Lab at Boise State University.

Typical Uses

Gems excel in situations where traditional multichannel data loggers and cabled sensors are too heavy, visible, or difficult to set up, or where more flexibility in instrumentation layout is needed. Past examples:

  • A 22-element array for recording earthquake aftershocks (Anderson et al., in prep)

  • Concealed single-sensor installations in highly theft-prone sites

  • Flying on stratospheric balloons (e.g., Bowman and Albert, 2018)

  • Hanging from a cable across a volcanic crater (Rosenblatt et al., 2022)

  • Network of individual sensors spaced 500 m apart extending radially from a volcanic vent

  • Ordinary infrasound arrays where cabled instruments are inconvenient due to dense vegetation, difficult terrain, or risk of theft

Loans
