National Coral Reef Monitoring Program: Calcification rates of crustose coralline algae derived from calcification accretion units (CAUs) deployed in the Florida Reef Tract

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 08:14 AM | Dataset Last Updated: September 28, 2022 at 12:00 AM
The calcification rate data described here are from in-house developed calcification accretion units (CAUs) deployed by scuba divers in the Florida Reef Tract, in accordance with protocols developed by Price et al. (2012), and as a part of NOAA's ongoing National Coral Reef Monitoring Program (NCRMP). CAUs allow for recruitment and colonization of Crustose Coralline Algae and hard corals. By measuring the change in weight of the CAUs, the reef carbonate accretion rate can be calculated for that time period. Monitoring net accretion over successive deployments allows for the detection of changes in calcification rates over time. This study provides information about spatial patterns of algal 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.
