REFERENCES AND ARTICLES ON THE MOLECULAR-ELECTRONIC SENSORS' APPLICATIONS

2014

An Article "Asymmetric caldera-related structures in the area of the Avacha group of volcanoes in Kamchatka as revealed by ambient noise tomography and deep seismic sounding." in Journal of Volcanology and Geothermal Research This incredible work studies the volcanoes activity for a year time span. The areas of observation are accessible for a couple of month in mid-summer, so the equipment was left for another 10 month and the data were picked up a year after the deployment. Data loggers Baikal-ACN-87 and broadband sensors CME-4311 were used in this experiment.

2014

A Leaflet "Low-Frequency Seismic Sounding (LFS)" from our partners - CJSC Gradient. The company has a profound experience in using the seismic sensors CME-4111 и CME-4311 along with seismic recorders Baykal-ACN for seismic exploration.

2014

An Article "A real-time seismic and tsunami network in the Kyparissiakos Gulf, Greece." The buoy and satellite stations were equipped with broadband CME-4011-OBS seismic sensors of 30 s to 50 Hz, while all other locations used 3C refraction geophones of 4.5 Hz natural frequency. Among other results, the article describes the efficiency of the station equipped with molecular-electronic seismometer.
