Arctic Airborne Magnetic Anomaly Transects from Devon Ice Cap, 2018

Airborne magnetic anomaly profiles collected over the Devon Ice Cap in the Canadian Arctic in 2018. The data was gathered using a Basler aircraft equipped with high-precision scalar and fluxgate magnetometers, measuring the Earth's magnetic field intensity and orientation. This product provides processed magnetic anomaly profiles after subtracting a background field model, intended for subsurface geological analysis.

Use Cases

• Model subsurface geological composition based on magnetic anomaly profiles.
• Analyze regional crustal structure in polar regions based on airborne magnetic field measurements.
• Integrate magnetic data with simultaneous radar and laser datasets for multi-sensor geophysical studies.
• Study magnetic field orientation and intensity variations in the Arctic based on scalar and fluxgate magnetometer readings.

Strengths

• Data collection used a high-precision scalar magnetometer for field intensity.
• Includes orientation data from a 3-axis fluxgate magnetometer.
• Specific collection details are provided: aircraft (Basler C-GJKB), base (Resolute Airport), year (2018), and target (Devon Ice Cap).
• Data was collected simultaneously with radar and laser datasets, enabling potential multi-modal analysis.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• The product does not include further processing steps like diurnal variation removal or leveling.
