NOTE: A standard TA installation now includes a QEP and Environmental Channels. Excluding the purchase of the sensor, vault equipment, QEP, Environmental Channels, and communications and power systems specified above, the average cost for permitting, excavation, construction, and installation of a Transportable Array station is $21,000. A 6-channel DAS system costs an additional $1,100. Standard power for the vault is one solar panel and one battery. Each additional battery costs $200 and each solar panel costs $450. |
Not all organizations have the necessary operations and maintenance support infrastructure to keep their newly acquired TA stations running. Organizations that adopt TA stations have the option to sign on for a subscription-based program (EARN Services) that provides the technical services to ensure that former Transportable Array stations continue operating and contributing data to the IRIS Data Management Center. Subscription rates are based on the communications technology present at the stations and average about $5,000 per year. See the Education and Research Network Support Services brochure for more information.
