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

Yukon, Canada, contains a map of the first vertical derivative of the magnetic field derived from an aeromagnetic survey flown from May 16 to July 1, 2009. The survey was conducted by Goldak Airborne Surveys using a cesium vapour magnetometer mounted on a Piper Navajo aircraft. The nominal traverse line spacing was 400 m, control line spacing was 2400 m, and the aircraft flew at a nominal terrain clearance of 150 m.

Use Cases

• Geological mapping based on magnetic anomaly patterns.
• Mineral exploration targeting based on derivative magnetic field data.
• Regional geophysical analysis based on high-resolution aeromagnetic survey data.
• Integrating magnetic data with other geoscience datasets for subsurface modeling.

Strengths

• Survey details are precisely documented, including the contractor (Goldak Airborne Surveys), instrument (split-beam cesium vapour magnetometer), and aircraft (Piper Navajo).
• Flight parameters are specified with nominal values: 400 m traverse line spacing, 2400 m control line spacing, and 150 m terrain clearance.
• The temporal coverage of the data acquisition is explicitly stated as May 16 to July 1, 2009.

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.
