Antarctic Seafloor Image Annotations from 21 Campaigns (1985-2019)

632,252 expert annotations for Antarctic seafloor imagery collected between 1985 and 2019, managed by the Australian Ocean Data Network. Annotations follow the CATAMI classification scheme and include point grids and bounding boxes for mobile fauna and Vulnerable Marine Ecosystem species. This data can support research into species distribution, community patterns, and training automated detection algorithms.

Use Cases

• Investigate species distributions and community patterns based on expert annotations across 21 research campaigns.
• Assess ecological change over time using the 34-year temporal coverage from 1985 to 2019.
• Train machine learning algorithms for automatic detection and annotation of marine fauna based on point grid and bounding box annotations.
• Study Vulnerable Marine Ecosystem species based on the dedicated bounding box annotation set.

Strengths

• Contains 632,252 expert annotations, indicating a substantial volume of labeled data.
• Annotations are based on the standardized CATAMI classification scheme and have been reviewed by experts.
• Covers 21 Antarctic research campaigns over a 34-year period from 1985 to 2019, providing temporal depth.
• Includes three distinct annotation types per campaign: point grids, bounding boxes for mobile fauna, and bounding boxes for select benthic species.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment for specific modeling tasks.
• Data may reflect geographic and temporal bias inherent to the specific 21 Antarctic research campaigns.
