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

May 16 to July 1, 2009 aeromagnetic survey data from the Northern Stevenson Ridge area in Yukon, Canada. The Government of Yukon published this processed map of the first vertical derivative of the magnetic field. Data was acquired by Goldak Airborne Surveys using a cesium vapour magnetometer flown at a nominal terrain clearance of 150 meters.

Use Cases

• Map subsurface geological structures based on magnetic field gradients.
• Support mineral exploration targeting based on magnetic anomalies.
• Conduct geophysical research based on high-resolution aeromagnetic data.
• Integrate magnetic derivative data with other geological datasets for regional analysis.

Strengths

• Survey conducted over a defined period from May 16 to July 1, 2009.
• Data acquired with a specific instrument: a split-beam cesium vapour magnetometer.
• Flight parameters are specified: 400 m traverse line spacing, 2400 m control line spacing, and 150 m nominal terrain clearance.

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 2009 survey.
