A digitally telemetered network of 31 IRIS-PASSCAL Guralp 40-T seismometers was installed in September and October, 1999 northeast of Yellowstone National Park as part of the NSF-funded Continental Dynamics Project, "Geodynamics of the Yellowstone Hotspot."
Continuously streamed digital data (sampled at 40 sps) from the three-component broadband seismometers are transmitted to two collection towers via spread-spectrum radios and relayed to a collection site in Billings, MT using a 2.2 GHz microwave radio. The data are linked to the Internet and are fed into our primary object ring buffer (ORB) at the University of Utah supplied by the Antelope software system. Data from four additional networks in the intermountain west spanning an area ~1,200 km north-south and ~500 km east-west are being collected along with the Montana broadband data including all or part of the following networks: the University of Utah Seismograph Stations, the Montana Bureau of Mines, the Idaho National Environmental Engineering Laboratory, and the U.S. National Seismic Network. We will soon be recording stations within the U.S. Bureau of Reclamation's Teton Network as well as stations operated by the University of Nevada-Reno. Over 150 seismograph stations with nearly 300 total channels are being fed into the ORB and recorded in real time. The size of the survey area and the amount of data represent a prototype for the USArray. Many logistical problems that may occur during that project may be foreseen with this ISIS network.
