    • National Coral Reef Monitoring Program: Calcification rates of crustose coralline algae derived from calcification accretion units (CAUs) deployed in Puerto Rico

    Metadata Updated: November 1, 2023

    The calcification rate data described here are from calcification accretion units (CAUs) that have been retrieved (and replaced) at existing, long-term monitoring sites during the NOAA Atlantic Oceanographic and Meteorological Laboratory (AOML) led NCRMP missions in Puerto Rico and processed at the NOAA Pacific Islands Fisheries Science Center. CAUs are PVC settlement plates that facilitate the recruitment and colonization of crustose coralline algae, hard corals, and other reef calcifiers. Laboratory experiments show that CCA and coral calcification rates are strongly correlated with seawater chemistry, and shifts in carbonate chemistry conditions due to ocean acidification could lead to reduced calcification and accretion rates and ecological phase shifts in coral reef communities.

    Coral reef calcium carbonate accretion rates can be estimated by measuring the change in weight of the CAUs between deployment and retrieval. Monitoring net accretion over successive deployments allows for the detection of changes in reef calcification rates over time. The number of processed CAUs for a site may be less than the number deployed, either because the units were lost or damaged at sea and therefore not recovered, or in rare instances, due to errors during laboratory processing.

    This study provides information about spatial and temporal patterns of reef carbonate calcification and accretion rates and serves as a basis for detecting changes associated with changing seawater chemistry due to ocean acidification. These data can also be used in comparative analyses across natural gradients, thereby assisting efforts to determine whether key reef-building taxa can acclimatize to changing oceanographic environments. These data will have immediate, direct impacts on predictions of reef resilience in a higher carbon dioxide (CO2) world and on the design of reef management strategies.
