GroundMetrics proposes to conduct two electromagnetic surveys at the Big Sky Carbon Sequestration Partnerships Kevin Dome location, one before and one after planned carbon dioxide (C02) injection. The C02 injection is a separate, independent activity not being conducted under this project. The purpose of this project is to demonstrate that electromagnetic measurements can be used to image the propagation of a C02 plume underground.
