The presence of the USArray's Transportable Array provides a unique opportunity for regional networks, educational institutions, or other entities to acquire a state-of-the art, fully operating seismic station for the cost of equipment. USArray, in cooperation with the National Science Foundation, the agency that funds the EarthScope project, will coordinate the transfer of Transportable Array stations to organizations interested in operating a single seismic station, starting a seismic network, or expanding or upgrading an existing network. This program enables adopting organizations to gain an asset at significant savings while enhancing their monitoring and educational capabilities, and cooperating in national-level research.
Organizations can develop a high-quality, proven, installed earthquake recording station for less than the total cost of construction and equipment to:
As the Transportable Array moves into a new area, USArray personnel make a concerted effort to work with local and regional organizations to optimize sites for Transportable Array stations, upgrade or construct new vaults, and introduce new broadband instrumentation. During the initial contact phase, it is recommended that organizations interested in adopting a Transportable Array station begin to plan for this transition. USArray is obligated to deploy and dismantle Transportable Array stations at a fixed rate and should be notified of intentions to adopt stations at least six months before the planned station removal date to minimize the impact on the Transportable Array field schedule.

STS-5 or T120PH Broadband Posthole Seismometer | $25,000 | Genasun Battery System (LiFePO4) | $18,900 |
Hut and Equipment (3-channel Q330, Baler, VIE, QEP w/Environmental Channels, GPS, etc.) | $14,700 | AGM Battery System (Pb Acid) | $10,800 |
Atmospheric Sensors (Microbarometer, Infrasound) | $2,500 | Inmarsat BGAN | $1,300 |

Typical Configuration Total: $64,900 | |||
Items not colored blue reflect different configurations in station design and are not reflected in the total. A 6-channel DAS system costs an additional $1,100. The power system covers three solar panels and either 6 Genasun and 4 secondary AGM batteries or 16 AGM batteries. III. Ongoing CostsThe estimated approximate costs to operate a station per year vary by site and depend on access ($50-$1500) and telemetry ($1,200 for cell, $2,700-$3,300 for DSL or DSL with radio, or $15,000 or more for BGAN). Costs are likely to vary in the future. EARN services similar to those offered in the Lower 48 may be available if the IRIS facility is operating in Alaska significantly beyond 2019. |
