AGU Poster Cascadia Borehole
This poster shows a comparison of 1000 ft deep borehole Silicon Audio 203-60 sensor with geophones and a fiber distributed acoustic sensor (DAS). We especially liked the quote below: For microearthquakes, assuming frequency range of above 2 Hz, the SA-ULN sensor would be the ideal choice. Correa, et al. (2020) Exploring the limits of fiber-optic sensing in Cascadia: Borehole passive seismic monitoring using co-located DAS, low noise optical accelerometers, and…

AGU Poster for SIIOS
Check out the AGU poster for one of the projects we are working on for NASA. The Seismometer to Investigate Ice and Ocean Structure (SIIOS) project is advancing the maturity of a commercial off the shelf (COTS) optical seismic sensor for spaceflight. The primary mission targets for SIIOS include landed spacecraft sent to the icy satellites in the outer solar system, including Europa. SIIOS will provide direct geophysical measurements that…
