Overview map showing broadband Golay array (yellow pins)
The Golay broadband array, composed of 6 smaller 3-station miniarrays, was designed to test the feasibility of recording seismic energy from a large array with a minimum number of stations. These 18 stations were installed by IRIS/PASSCAL staff (with volunteer support) in June 2016 alongside the gradiometer and seismic lines. Unlike the node deployment (which lasted 30 days), the Golay stations were deployed from June to November (5 months) and were fortunate to record the Oct-9 Pawnee, OK M5.8 quake.
