Aeromagnetic Survey Data for Yukon and Northwest Territories, 2003

Yukon Territory and Northwest Territories aeromagnetic survey data collected in 2003. Goldak Airborne Surveys conducted the survey using two Piper Navajo aircraft from July 18 to September 2, 2003. The levelled total field values were interpolated to a 200 m grid, and the International Geomagnetic Reference Field has not been removed.

Use Cases

• Map subsurface magnetic anomalies for mineral exploration based on aeromagnetic total field data.
• Analyze regional geological structures based on interpolated 200 m grid magnetic values.
• Validate or calibrate other geophysical models using data from a 0.005 nT sensitivity magnetometer.
• Study magnetic field variations in northern Canada based on survey data where the IGRF has not been removed.

Strengths

• Survey conducted with a 0.005 nT sensitivity split-beam cesium vapour magnetometer.
• Data levelled and interpolated to a 200 m grid.
• Flight path recovered using post flight differential GPS and a vertically mounted video camera.
• Survey operations carried out over a defined period from July 18 to September 2, 2003.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The International Geomagnetic Reference Field has not been removed from the magnetic total field.
