Antarctic marginal ice zone width data underpins the Fraser et al., 2026 publication in Nature Communications. The data are presented as one CSV file per year, each containing around 8500-9000 rows corresponding to SARAL half-orbit summaries. The Australian Ocean Data Network published these wave-in-ice climatology records on April 16, 2026.
Use Cases
- Analyze decade-long trends in Antarctic marginal ice zone width based on the annual CSV files.
- Validate wave-ice interaction models based on the estimated inner MIZ limit from radar altimeter waveforms.
- Map the spatial extent of wave-affected sea ice based on the along-track summary fields.
- Correlate ice edge latitude with wave passage detection based on the waveform 'peaky' and 'steep' criteria.
Strengths
- Data underpins a peer-reviewed publication in Nature Communications.
- Each annual file contains around 8500-9000 rows of along-track summary data.
- Provides a decade-long wave-in-ice climatology for the Antarctic region.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown for the full collection, which may limit suitability assessment.
