Large-bodied Fish Surveys in Hawaiian Coral Reefs from 2016

NOAA towed-diver surveys recorded the number, size, and species of large-bodied fishes (> 50 cm) in Hawaiian coral reefs. Data were collected in 2016 by the Coral Reef Ecosystem Program using a standardized 50-minute towed-diver method. Observations are segmented into 10 5-minute intervals across approximately 2–3 km of reef habitat.

Use Cases

• Modeling population density of large-bodied reef fish based on species and size observations
• Analyzing spatial distribution of fish assemblages across surveyed reef habitats
• Assessing coral reef ecosystem health based on fish community composition
• Monitoring changes in fish populations over time using standardized survey methods

Strengths

• Data collected using a standardized NOAA towed-diver survey method over 50-minute intervals
• Focuses on large-bodied fishes (> 50 cm), a key ecological indicator group
• Observations are segmented into 10 5-minute periods for temporal granularity

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• Data is from a single year (2016), limiting temporal trend analysis
