Mariana Archipelago Coral Reef Benthic Complexity and Urchin Abundance Since 2014

Mariana Archipelago data on benthic structural complexity and urchin abundance collected by NOAA's Pacific Islands Fisheries Science Center since 2014. The data provide baselines from climate stations selected via stratified random sampling along the 15-meter contour. These variables are monitored as important indicators of coral reef ecosystem health and community structure.

Use Cases

• Modeling relationships between benthic complexity and reef fish density/biomass based on described ecosystem correlations.
• Tracking long-term changes in urchin abundance and algal cover at established climate stations.
• Establishing baselines for structural complexity to assess reef recovery or degradation over time.
• Analyzing correlations between in-situ temperature (STR) data and benthic community indicators.

Strengths

• Data collection began in 2014, providing a multi-year time series.
• Climate stations were selected using a stratified random sampling method for spatial representativeness.
• Monitoring includes multiple reef environment features: in-situ temperature, seawater carbonate, net carbonate accretion, bioerosion, and cryptobiota diversity.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
• Data is stored in PDF format, which may complicate direct analysis.
