Geophysical Technician

Skills at this level

Geophysical Data Acquisition

— Sets out and operates seismic, gravity, and magnetic instruments at survey stations, capturing surface and subsurface readings against a station plan under field conditions.

Field Survey Operations

— Collects field samples and observations outdoors across varying weather and terrain, sequencing station work and equipment logistics to meet daily acquisition targets.

Data Quality Control

— Checks acquired geophysical data for coverage gaps, noisy traces, and instrument drift, and judges when readings must be re-shot before they enter the database.

Geophysical Data Processing

— Runs raw seismic, gravity, and magnetic data through established filtering, gridding, and correction routines to produce clean datasets ready for interpretation.

Geophysical Database Maintenance

— Files and reconciles field logs and processed data into geophysical databases using standard naming and QC conventions, keeping records complete and traceable.

Instrument Setup and Troubleshooting

— Calibrates, configures, and diagnoses faults in geophysical instrument arrays, adapting setups for difficult terrain or novel method combinations in the field.

Technical Report Preparation

— Derives figures, coverage maps, and report sections from processed field data, presenting acquisition results in the documentation used by professional geophysicists.

Procedure Development

— Creates and documents new acquisition, processing, and QC procedures and instrument-handling standards adopted across the geophysics operation.

Data Interpretation Support

— Assembles and pre-conditions processed geophysical datasets so professional staff can interpret subsurface conditions and hazards, flagging anomalies for their attention.

Field Communication

— Conveys station notes, data-quality issues, and processing status clearly to crew, senior geophysicists, and clients, both in field logs and technical handoffs.

Computing and Data Handling

— Uses geophysical software and computer systems to enter, process, and manage acquisition data and generate deliverable products.

Field Crew Coordination

— Guides less experienced technicians on acquisition and QC tasks, sequences crew work, and reviews their processed outputs before release as a working lead.
