SASSIE: Arctic Sea Ice Radar Imagery from 2022 Field Campaign

The Beaufort Sea during August-October 2022 is the focus of this dataset, which contains georeferenced S-band marine radar images from the NASA SASSIE field campaign. Images were collected every 10-60 seconds from the R/V Wolstad within ~200 km of the sea ice edge. Level 4 processed GeoTIFFs classify pixels as sea ice, not sea ice, or not data.

Use Cases

• Validating sea ice concentration models based on pixel-level classification in radar imagery.
• Analyzing the spatial transition from open water to sea ice based on georeferenced image sequences.
• Studying upper ocean stratification effects on sea ice growth using temporally dense radar observations.
• Training machine learning models for sea ice detection using pre-classified radar image pixels.

Strengths

• Data includes Level 4 processing with pixel classification (sea ice, not sea ice, not data).
• Images are georeferenced using ship GPS, heading, and radar range, enabling spatial analysis.
• Temporal resolution is high, with images captured every 10-60 seconds during ice operations.

Limitations

• Key metadata is missing: total number of images, file sizes, and specific column/attribute details are not provided.
• Conflicting 'last updated' dates exist between sources (2022-09-30 vs. 2026-04-09), creating uncertainty about versioning.
• The license is ambiguously listed as 'other-license-specified' without explicit terms.
