First Vertical Derivative of the Magnetic Field, Northern Stevenson Ridge Yukon 2009

Northern Stevenson Ridge in Yukon, Canada, is covered by this map of the first vertical derivative of the magnetic field. The data was acquired by Goldak Airborne Surveys from May 16 to July 1, 2009, using a cesium vapour magnetometer mounted on a Piper Navajo aircraft. Survey lines were flown at a nominal terrain clearance of 150 meters with traverse and control line spacings of 400 m and 2400 m, respectively.

Use Cases

• Map subsurface geological structures based on magnetic field gradients.
• Support mineral exploration targeting by identifying magnetic anomalies.
• Integrate with other geophysical data for regional geological interpretation.
• Calibrate or validate airborne magnetic survey methodologies.

Strengths

• Specific acquisition dates (May 16 to July 1, 2009) are provided.
• Detailed survey parameters are documented, including 150 m terrain clearance and 400 m traverse line spacing.
• Data is provided by a government organization (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 and temporal bias inherent to a single survey.
