Nisling River Aeromagnetic Survey: First Vertical Derivative, 2011 Yukon

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

Use Cases

• Map subsurface geological structures based on processed magnetic field data.
• Identify potential mineral deposits based on magnetic anomalies described in the survey.
• Integrate magnetic data with other geophysical datasets for regional geological modeling.
• Calibrate magnetic survey methodologies based on the detailed equipment and flight parameters provided.

Strengths

• High-resolution data collection over 37,999 line kilometres.
• Detailed survey methodology described, including 400 m traverse line spacing and 100 m terrain clearance.
• Data processed and plotted, suggesting a level of quality control.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Data freshness should be verified as the last metadata update is listed for 2026-05-20.
• The dataset may reflect geographic bias inherent to the specific survey area in Yukon.
