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

Yukon, Canada, specifically NTS map sheets 115K/15 and 115K/16. This dataset is a processed map of the first vertical derivative of the magnetic field derived from an aeromagnetic survey flown between May 16 and July 1, 2009. The survey was conducted by Goldak Airborne Surveys using a cesium vapour magnetometer mounted on a Piper Navajo aircraft flying at a nominal 150-meter terrain clearance.

Use Cases

• Geological mapping based on magnetic anomaly patterns.
• Mineral exploration targeting based on subsurface magnetic structures.
• Regional geophysical analysis based on high-resolution aeromagnetic data.
• Integrating magnetic data with other geological datasets for 3D modeling.

Strengths

• Survey conducted with specific technical parameters: 400 m traverse line spacing and 2400 m control line spacing.
• Data acquired using a split-beam cesium vapour magnetometer, a standard instrument for high-resolution surveys.
• Clear temporal scope: data collection occurred from May 16 to July 1, 2009.
• Defined geographic scope focused on the Northern Stevenson Ridge area in 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/temporal bias inherent to the specific survey area and period.
