632,252 expert annotations for seafloor imagery collected during 21 Antarctic research campaigns between 1985 and 2019. The annotations are part of the Antarctic Seafloor Annotated Imagery Database (AS-AID) and follow the CATAMI classification scheme. They have been reviewed by experts and are accessible via the Squidle+ platform.
Use Cases
- Investigate species distributions based on expert annotations of benthic and mobile fauna.
- Analyze community patterns using point grid and bounding box annotations.
- Assess ecological change over time using annotations spanning 34 years.
- Train automated detection algorithms based on bounding box annotations for mobile fauna and vulnerable benthic species.
Strengths
- 632,252 expert-reviewed annotations provide a substantial labeled dataset.
- Annotations span 21 research campaigns over a 34-year period (1985-2019).
- Annotations follow a standardized classification scheme (CATAMI).
- Three distinct annotation sets (point grid, bounding boxes for mobile fauna, bounding boxes for vulnerable benthic species) offer multiple analysis perspectives.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count and dataset size are unknown, which may limit suitability assessment.
- Data may reflect temporal and geographic bias inherent to the specific Antarctic research campaigns.
