National Coral Reef Monitoring Program: Calcification rates of crustose coralline algae derived from calcification accretion units (CAUs) deployed across the Hawaiian Archipelago

browse graphicPreview graphic
The calcification rate data in this collection are from Calcification Accretion Units (CAUs) that have been retrieved and replaced at existing, long-term monitoring sites during NOAA Pacific Islands Fisheries Science Center (PIFSC), Coral Reef Ecosystem Program (CREP) led NCRMP missions, in accordance with protocols developed by Price et al. 2012. There are typically (but not always) five CAU sites established at each location CREP visits, with five units deployed at each site.

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. In conjunction with benthic community composition data (archived separately), the calcification rates will aid in determining the magnitude of how ocean acidification affects coral reefs in the natural environment.

Calcification accretion units (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 Archipelago as part of the ongoing NOAA National Coral Reef Monitoring Program (NCRMP).

CAUs are composed of two 10 x 10 cm flat, square, gray PVC plates, stacked 1 cm apart, and are attached to the benthos using stainless steel threaded rods. Calcareous organisms, primarily crustose coralline algae and encrusting corals, recruit to these plates and accrete/calcify carbonate skeletons over 2-3 year deployments. By measuring the change in weight of the CAUs, the reef carbonate accretion rate can be calculated for that time period. Due to the simple, low-cost design and analysis, statistically robust numbers of calcification plates can easily be deployed, recovered, and processed to provide estimates of net calcification. Monitoring net accretion over successive deployments allows for the detection of changes in calcification rates over time.
Purpose 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 and the NOAA Ocean Acidification Program (OAP), 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 Coral Reef Ecosystem Program (CREP) 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).
