NOAA's Coral Reef Ecosystem Program collected calcification rate data from Calcification Accretion Units deployed across American Samoa and the Pacific Remote Island Areas in 2010 and 2012. The dataset measures carbonate accretion by crustose coralline algae and corals over 2-3 year deployments to assess impacts of ocean acidification. Data is accessible via the NOAA National Centers for Environmental Information Ocean Archive.
Use Cases
- Analyze spatial patterns of algal calcification rates across Pacific reef sites.
- Monitor changes in reef carbonate accretion over time based on successive CAU deployments.
- Correlate calcification rates with seawater carbonate chemistry parameters.
- Assess ecological phase shifts in reef communities due to reduced calcification.
- Compare calcification data with benthic community composition data for holistic reef impact studies.
Strengths
- Data collection follows standardized protocols developed by Price et al. 2012.
- Typically five sites per location with five units per site, providing a replicated sampling design.
- Deployments span 2-3 years, allowing for measurement of net accretion over time.
Limitations
- Column-level documentation is absent; field semantics must be inferred after download.
- Row count is unknown, which may limit suitability assessment.
- Data format is PDF, which may complicate direct analysis.
