First Vertical Derivative Magnetic Field Map, Northern Stevenson Ridge Yukon

May 16 to July 1, 2009 aeromagnetic survey data collected by Goldak Airborne Surveys over the Northern Stevenson Ridge area in Yukon, Canada. The data were recorded using a split-beam cesium vapour magnetometer mounted on a Piper Navajo aircraft. The survey had a nominal traverse line spacing of 400 m, control line spacing of 2400 m, and a terrain clearance of 150 m.

Use Cases

• Map subsurface geological structures based on magnetic field gradients.
• Identify potential mineral deposits based on magnetic anomaly patterns.
• Integrate with other geophysical data for geological interpretation based on the processed derivative map.

Strengths

• Survey conducted with specific technical parameters: 400 m traverse line spacing, 2400 m control line spacing, and 150 m terrain clearance.
• Data acquisition period is precisely defined as May 16 to July 1, 2009.
• Data is provided by the Government of Yukon under an open license (OGL-CA-2.0).

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.
