Nisling River Aeromagnetic Survey First Vertical Derivative, Yukon 2011

Goldak Airborne Surveys conducted a high-sensitivity aeromagnetic survey for the Geological Survey of Canada between January 25 and March 26, 2011. The survey collected 37,999 line kilometres of high-resolution magnetic data over the Nisling River area. Traverse lines were flown at a 400 m spacing with control lines at 2400 m separation and a nominal terrain clearance of 100 meters.

Use Cases

• Model subsurface geological structures based on high-resolution magnetic field data.
• Assist mineral exploration targeting based on processed magnetic anomaly maps.
• Calibrate geophysical survey methodologies based on detailed equipment and flight specifications.

Strengths

• 37,999 line kilometres of high-resolution magnetic data provide substantial spatial coverage.
• Survey specifications include precise parameters: 400 m line spacing, 2400 m control line separation, and 100 m nominal terrain clearance.
• Data collection utilized multiple cesium vapour magnetometers and differential GPS for positioning.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified; the last metadata update was 2026-05-20.
• The specific data format (GEDAS binary) may require specialized software for access and processing.
