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 vault construction and equipment to:
- use as an educational resource
- record ground motion from local, regional, and global events
- supplement an existing seismic network or start a new network
- expand U.S. seismic recording capability
Advantages to Adopting a Transportable Array Station
- A proven, installed station is obtained for less than the cost of the equipment alone.
- Permitting, construction, and installation costs are borne by USArray.
- One-time costs are clearly defined.
- First-time operators are provided with an established operational structure.
- Transportable Array station design has demonstrated scientific value and technical feasibility.
- Individual station performance is available for review prior to adoption.
- Operations and maintenance support of stations over the long term can benefit from access to Transportable Array volume-pricing contracts for equipment and engineered solutions, and engineering support services.
- The station can contribute data to the Advanced National Seismic System, a nationwide network of earthquake sensor systems that continuously monitor earthquakes and other seismic disturbances throughout the United States and provide real-time information for emergency response personnel.
Early Planning is Essential
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.

Maintenance & Operations Outlay
The estimated cost for maintenance is $5000 per year plus monthly fees for real-time communications service. This cost does not include central site acquisition software or personnel.
|
Conditions: 1. New operator must provide identical equipment to the Transportable Array either through purchase or funds transferred to the USArray program. 2. New operator must obtain a permit from the landowner for continued operation beyond the Transportable Array permit duration. 3. Data from the station must be made publicly available via the IRIS Data Management Center. 4. The Transportable Array installation schedule cannot be disrupted by the new operator’s field operations or equipment acquisition procedures. |
