Nisling River Aeromagnetic Survey, Yukon, 2011

Yukon's Nisling River area (NTS 115 J/5, 6) was surveyed by Goldak Airborne Surveys for the Geological Survey of Canada from January 25 to March 26, 2011. The survey collected 37,999 line kilometres of high-resolution magnetic data using cesium vapour magnetometers with a 400 m traverse line spacing. Data were recorded digitally in GEDAS binary format with differential GPS corrections.

Use Cases

• Model subsurface geological structures based on high-resolution magnetic field measurements.
• Support mineral exploration targeting by identifying magnetic anomalies indicative of ore deposits.
• Create regional geophysical maps for geological mapping and research based on the 400 m line-spaced survey grid.

Strengths

• High-resolution data collection over 37,999 line kilometres.
• Survey conducted with three cesium vapour magnetometers and differential GPS for positional accuracy.
• Specific flight parameters provided, including 400 m traverse line spacing and 100 m nominal terrain clearance.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified; the last metadata update is listed as 2026-05-20.
• The available file formats (PDF, ZIP, HTML) suggest the primary data may require specialized software for processing.
