National Coral Reef Monitoring Program: Calcification Rates of Crustose Coralline Algae Derived from Calcification Accretion Units (CAUs) Deployed across the Hawaiian Archipelago in 2012 and 2013 and Retrieved in 2016 (NCEI Accession 0175167)

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 Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD) led NCRMP mission around the Hawaiian Archipelago in 2016, in accordance with protocols developed by Price et al. 2012. Five units were deployed on the seafloor at each CAU site for 3-4 years; with 14 CAUs deployed in 2012 recovered from around Oahu, and 186 CAUs deployed in 2013 recovered from across the archipelago. 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 there was an error during processing.

CAUs allow for recruitment and colonization of CCA 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.

Purpose CAUs are used to assess the current effects of changes in seawater carbonate chemistry on calcification and accretion rates of calcareous and fleshy algae in the Hawaiian and Mariana Archipelagos, American Samoa, and the Pacific Remote Island Areas as part of the NOAA National Coral Reef Monitoring Program (NCRMP). Laboratory experiments reveal calcification rates of crustose coralline algae (CCA) are strongly correlated to seawater aragonite saturation state. Predictions of reduced coral calcification rates, due to ocean acidification, suggest that coral reef communities will undergo ecological phase shifts as calcifying organisms are negatively impacted by changing seawater chemistry. The NOAA National Coral Reef Monitoring Program (NCRMP) details a long term approach to provide an ecosystem perspective via monitoring climate, fish, benthic, and socioeconomic variables in a consistent and integrated manner. The NCRMP is intended to coordinate various NOAA Coral Reef Conservation Program (CRCP) biological, physical, and human dimensions activities into a cohesive NOAA-wide effort. Through the implementation of the NCRMP, NOAA will be able to clearly and concisely communicate results of national-scale monitoring to national, state, and territorial policy makers, resource managers, and the public on a periodic basis. To support a long-term Coral Reef Conservation Program for sustainable management and conservation of coral reef ecosystems, calcification and accretion rates of reef-building crustose coralline algae are measured in order to establish a baseline for change due to ocean acidification within the coral reef environments the NOAA Ecosystem Sciences Division (ESD) monitors. SCUBA divers deploy in-house developed calcification accretion units (CAUs) at forereef study sites established by the ongoing Pacific Reef Assessment and Monitoring Program (RAMP).
