Northern Stevenson Ridge Aeromagnetic Survey, Yukon (2009)

Yukon, Canada, is covered by this map of the residual total magnetic field. The data were acquired by Goldak Airborne Surveys from May 16 to July 1, 2009, using a cesium vapour magnetometer flown at a nominal 150-meter terrain clearance. The survey used traverse lines spaced 400 meters apart and control lines spaced 2400 meters apart.

Use Cases

• Geological mapping based on magnetic field anomalies.
• Mineral exploration targeting based on subsurface magnetic structures.
• Integrating magnetic data with other geophysical surveys for regional analysis.
• Modeling bedrock geology based on variations in the residual total magnetic field.

Strengths

• Survey conducted with specific technical parameters: 150 m terrain clearance, 400 m traverse line spacing.
• Data acquisition period is precisely defined as May 16 to July 1, 2009.
• Data sourced from a professional airborne survey contractor (Goldak Airborne Surveys).

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count and data scale are unknown, which may limit suitability assessment.
• Data may reflect temporal and geographic bias inherent to a single, localized survey.
