Transforming Portable Seismic Data Acquisition: From Experiment Design to Publishing, an Ecosystem Approach

An important consideration in selecting instrumentation to support the undertaking of portable seismic campaigns has been the costs associated with physical attributes, namely Size, Weight, and Power.  A more holistic approach would be to examine the overall campaign lifecycle and the phases which have the greatest impact on science outcomes. In this regard, some of the key success factors are the decisions made during the deployment planning phase that includes network size, station geolocation, instrumentation and sensor choices. Often overlooked is the data management problem associated with ensuring that the most up-to-date information associated with the plan is communicated to everyone who needs it. Further, another often overlooked aspect is the accurate tracking and reporting of what actually is deployed in the field relative to the plan, since such deviations inevitably occur.

The Pegasus Data Acquisition System is an ecosystem of hardware and software components for portable seismic monitoring that fundamentally transforms how seismic campaigns are conducted. This integrated ecosystem-based approach to seismic data acquisition ensures that campaigns are easy to plan, execute and achieve superb outcome certainty and cost-efficiency. A range of Pegasus models have been designed specifically to support Portable, Polar and OBS campaigns. Seamlessly integrated workflows address all aspects of the campaign lifecycle from pre-planning to pre-configured deployments, harvesting ready-to-use complete data sets, configuration distribution to field technicians and automatically generated metadata.
