Assessing cryptic reef diversity of colonizing marine invertebrates using Autonomous Reef

Autonomous Reef Monitoring Structures (ARMS) deployed at coral reef sites in Batangas, Philippines from March 2012 to June 2015 collected cryptic marine invertebrates. The data were collected by the NOAA Coral Reef Ecosystem Program (CREP) using a standardized method with three ARMS units per site. Collected organisms were processed into size fractions for morphospecies sorting and preserved for DNA analysis.

Use Cases

• Analyze cryptic reef biodiversity trends based on standardized ARMS sampling
• Compare invertebrate community composition across different reef sites based on the described sampling locations
• Study recruitment patterns of sessile and motile organisms based on the described plate scraping and sieving methods
• Monitor changes in marine cryptobiota over time based on the multi-year deployment period

Strengths

• Standardized sampling method using identical ARMS units ensures comparability across sites and time
• Data collection spanned over three years from March 2012 to June 2015
• Processing included multiple size fractions (2 mm, 500 µm, 100 µm) and preservation for both morphological and DNA analysis

Limitations

• Column-level documentation is absent; field semantics must be inferred after download
• Row count is unknown, which may limit suitability assessment
• The primary data format is PDF, which may require extraction for quantitative analysis
