Residual total magnetic field, Northern Stevenson Ridge Aeromagnetic Survey, NTS 115K/15 a

Aeromagnetic data was collected from May 16 to July 1, 2009 by Goldak Airborne Surveys over two map sheets in Yukon, Canada. The survey used a cesium vapour magnetometer flown at a nominal terrain clearance of 150 meters. The Government of Yukon provides the processed residual total magnetic field map derived from this survey.

Use Cases

• Map subsurface geological structures based on magnetic field variations.
• Identify potential mineral deposits based on magnetic anomaly patterns.
• Integrate magnetic data with other geophysical surveys for regional geological modeling.
• Calibrate airborne survey equipment and methodologies using the detailed flight parameters.

Strengths

• Survey parameters are precisely documented, including a 150-meter terrain clearance and 400-meter traverse line spacing.
• Data collection period is explicitly stated as May 16 to July 1, 2009.
• The source organization is the authoritative Government of Yukon.

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 bias inherent to the specific survey area in Yukon.
