ICECAP: Reprocessed Airborne Magnetic Data Over Antarctica, 2008-2017

Reprocessed magnetic line data were collected by the ICECAP program during airborne surveys over Antarctica. The dataset covers two project phases, ICECAP-I (2008/2009 to 2012/2013) and ICECAP-II (2015/2016 to 2016/2017). Data were reprocessed to correct for temporal and spatial variations in magnetic field intensity and to account for differences in flight elevation and subglacial topography.

Use Cases

• Mapping subglacial geology and bedrock composition based on corrected magnetic intensity data.
• Analyzing temporal variations in the Earth's magnetic field over Antarctica from the time-series data.
• Correlating magnetic anomalies with subglacial topography and flight elevation data mentioned in the processing description.
• Integrating reprocessed magnetic data with other geophysical datasets for a consolidated Antarctic subsurface model.

Strengths

• Data were reprocessed to correct for temporo-spatial variations, indicating a focus on accuracy.
• Covers a multi-year time range across two distinct project phases (ICECAP-I and ICECAP-II).
• Processing steps are documented in an included README file.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
