NOAA's Biogeography Branch conducted standardized field surveys across nearshore habitats in Puerto Rico to quantify reef fish and macro-invertebrate populations. The data links species distribution and abundance to underlying benthic composition and habitat maps from 2001. This effort supports the National Coral Reef Monitoring Program's goal to establish data standards for U.S. Caribbean territories.
Use Cases
- Model fish abundance and size distribution against mapped benthic habitat types and bathymetry.
- Assess macro-invertebrate (e.g., conch, lobster, Diadema) population trends in relation to in-situ benthic composition parameters.
- Identify spatial 'hot spots' of species richness and diversity using stratified random sampling data.
- Evaluate the efficacy of marine zoning strategies by comparing data from managed versus unmanaged areas.
- Standardize and compare reef fish community metrics across different U.S. Caribbean locations.
Strengths
- Data collection follows standardized protocols established for the National Coral Reef Monitoring Program, enabling cross-location comparison.
- Sampling design uses stratified random selection based on habitat maps to ensure coverage of the entire study region, not just specific reefs.
Limitations
- Specific sample size (row count), temporal coverage for the 2011 snapshot, and column details are not provided in the input.
- The description focuses on program goals and methodology; the actual dataset's granularity and completeness for 2011 are unclear.
Provenance
- Source
- NOAA National Centers for Environmental Information (NCEI), originating from the Center for Coastal Monitoring and Assessment's Biogeography Branch.
