Geophysical Series NTS 115J/4: Airborne Survey of Southern Stevenson Ridge, Yukon

A helicopter-borne geophysical survey flown from September 10 to October 14, 2008, collected quantitative gamma-ray spectrometric and aeromagnetic data. The survey was conducted by Fugro Airborne Surveys with a nominal terrain clearance of 125 meters. Traverse lines were spaced 400 meters apart and oriented at 0 degrees, with orthogonal control lines spaced 2400 meters apart.

Use Cases

• Map regional geological structures based on aeromagnetic data.
• Identify areas of anomalous natural radioactivity for mineral exploration based on gamma-ray spectrometry.
• Integrate geophysical data with geological maps to refine subsurface models.
• Assess the geophysical signature of the Southern Stevenson Ridge area for academic research.

Strengths

• Survey parameters are precisely documented, including line spacings of 400 m and 2400 m.
• Data collection period is explicitly defined as September 10 to October 14, 2008.
• Flight altitude is specified as a nominal terrain clearance of 125 m.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data may reflect geographic and temporal bias inherent to the specific 2008 survey.
