First Vertical Derivative of Magnetic Field, Kluane Area Yukon Aeromagnetic Survey 2010

A map derived from a helicopter-borne aeromagnetic survey flown between February 4 and March 15, 2010. Fugro Airborne Surveys collected the data using two Astar 350B aircraft equipped with cesium vapour magnetometers, flying at a nominal terrain clearance of 100 meters. The survey covered parts of NTS 115 H/11 and 115 H/12 in the Yukon, with traverse lines spaced 400 meters apart and oriented N30°E.

Use Cases

• Geological mapping based on magnetic field variations to identify subsurface structures.
• Mineral exploration targeting based on magnetic anomalies derived from high-sensitivity magnetometer data.
• Geophysical modeling based on the first vertical derivative of the total magnetic field.
• Survey methodology analysis based on the described flight parameters and data acquisition techniques.

Strengths

• Data acquired using high-sensitivity split-beam cesium vapour magnetometers with a sensitivity of 0.005 nT.
• Survey flown at a low nominal terrain clearance of 100 meters, likely providing high-resolution data.
• Flight path was recovered using post-flight differential GPS corrections and video camera inspection, suggesting accurate positioning.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for large-scale statistical analysis.
• Data may reflect geographic bias inherent to the specific survey area in the Yukon.
