Residual Total Magnetic Field Map, Northern Stevenson Ridge Aeromagnetic Survey, Yukon

Aeromagnetic survey data collected over the Northern Stevenson Ridge area in Yukon, Canada. The data were acquired by Goldak Airborne Surveys between May 16 and July 1, 2009, using a cesium vapour magnetometer mounted on a Piper Navajo aircraft. The resulting map shows the residual total magnetic field, with survey lines flown at a nominal terrain clearance of 150 meters.

Use Cases

• Geological mapping based on magnetic anomaly patterns.
• Mineral exploration targeting based on subsurface magnetic signatures.
• Integrating magnetic data with other geophysical surveys for regional analysis.
• Modeling subsurface structures based on the recorded magnetic field intensity.

Strengths

• Survey parameters are precisely documented, including a nominal terrain clearance of 150 meters.
• Specific acquisition dates (May 16 to July 1, 2009) and contractor (Goldak Airborne Surveys) are provided.
• Line spacing details are given, with traverse lines at 400 m and control lines at 2400 m.

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 in 2009.
