Sea Urchin Barrens Annotations from Towed Video, Tasmania East Coast

Annotations of Centrostephanus rogersii sea urchin barrens derived from towed video at selected key abalone blocks along the east coast of Tasmania. The data was created to examine the patch dynamics of urchin barrens and to provide validation for identifying barrens from multibeam surveys. It is hosted by the Australian Ocean Data Network and was last updated on 2026-06-04.

Use Cases

• Validate the identification of urchin barrens from multibeam surveys based on the video annotations.
• Analyze the spatial patch dynamics of sea urchin barrens based on the annotated towed video transects.
• Study the habitat impact of Centrostephanus rogersii sea urchins along the Tasmanian coast based on the annotated barren locations.

Strengths

• Annotations are derived from direct video observation, which likely provides a ground-truth reference.
• Data is hosted by the authoritative Australian Ocean Data Network.

Limitations

• Row count and column-level documentation are absent; field semantics must be inferred after download.
• The geographic scope is limited to selected key abalone blocks along the east coast of Tasmania.
