Green Sea Urchin Acoustic Telemetry and Tagging Experiment Data

Laboratory and field data evaluate four tagging methods for green sea urchins, including tag retention, survival, and condition metrics. The dataset contains verified laboratory measurements and raw acoustic telemetry detections from a field study. Results demonstrate the feasibility of acoustic telemetry for tracking urchin movement over ecologically relevant scales.

Use Cases

• Compare tag retention and survival rates across four tagging methods using laboratory data.
• Analyze the relationship between urchin condition metrics like gonad weight and righting time with different tagging attachments.
• Estimate space occupancy and movement from raw acoustic telemetry detection files for tagged individuals.
• Correlate field diver search results with laboratory survival data to validate tagging method effectiveness.

Strengths

• Data includes both controlled laboratory experiments and field observations, providing complementary evidence.
• Laboratory data and diver observations have undergone verification and quality control.
• The study compares four distinct tagging methods, offering a direct performance comparison.

Limitations

• The dataset size, including row and column counts, is unspecified, making it difficult to assess scope.
• Acoustic telemetry detections are provided as raw, unfiltered files requiring processing as described in the linked article.
• Field study observations are limited to specific checkpoints at one week and two months post-release.
