AVHRR Sea Ice Atlas for Eastern Antarctica, 1992-1999

A compilation of 500 Advanced Very High Resolution Radiometer (AVHRR) satellite images documenting sea ice conditions near five Antarctic stations from 1992 to 1999. Dr Kelvin Michael supervised the project for the Australian Antarctic Division, producing the atlas in both hard copy and digital formats. Images are renavigated onto a polar stereographic projection and include visible/thermal bands for summer and thermal-only for winter months.

Use Cases

• Monitoring long-term sea ice extent and conditions based on monthly satellite imagery for five specific Antarctic regions.
• Supporting ecological studies of marine vertebrates by providing visual context for sea ice habitat mentioned in the description.
• Analyzing seasonal ice patterns using the provided visible and thermal imagery for austral summer and winter months.
• Aiding navigation and operational planning for Antarctic shipping based on the compiled ice imagery.

Strengths

• Contains 500 curated images selected from approximately 20,000 consulted AVHRR scenes.
• Provides monthly coverage for a defined 8-year period (1992-1999) across five specific Antarctic station regions.
• Images are consistently processed with renavigation, gridding, added coastline, and a standardized polar stereographic projection.

Limitations

• Description metadata is limited; actual data quality requires manual inspection after download.
• Last updated 1999-12-31 23:59:59.999000; freshness should be verified.
• The description notes incomplete coverage due to missing data or lack of suitable imagery in some regions and months.
