Quality Control Tasks

Assure optimal field data collection techniques are employed
Review reporting and logging systems for content, consistency and accuracy
Monitor crew's compliance with HSE and permit requirements
Examine survey control and surveying techniques
Compare pre-plot and post-plot survey data for positioning errors
Review and approve any source or sensor repositioning due to hazards, culture or permit restrictions
Monitor source techniques, deployment, performance and logging
Check source synchronization and acquisition system timing
Monitor sensor deployment
Inspect, test and monitor recording instrumentation to ensure performance meets manufacturer's specifications
Review field records for reflector quality and signal to noise ratio levels
Produce detailed statistics on crew performance
Check file headers of the seismic data to ensure correct field geometry is applied to each trace and shot-point location (requires field QA system)

Produce interactive GIS database
