The calcification rate data described here are derived from Calcification Accretion Units (CAUs) that were deployed and retrieved at long-term climate monitoring sites during NOAA Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD) led National Coral Reef Monitoring Program (NCRMP) missions around the Hawaiian Archipelago in 2013, 2016, and 2019, as well as pre-NCRMP missions in 2010 and 2012. 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. Five units were deployed on the seafloor at each CAU site for 3 years. 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.
CAU data collected as part of NOAA National Coral Reef Monitoring Program (NCRMP) missions can be used to establish calcium carbonate accretion rate baselines and assess change in reef accretion rates due to ocean acidification and other environmental drivers.

After CAU units are deployed and recovered, the associated metadata is entered by the OCC team into the existing Oracle APEX mission application available on the research vessel, where it is eventually migrated to the NOAA Fisheries Pacific Islands Fisheries Science Center (PIFSC) enterprise Oracle database. Upon cruise completion, each CAU is given the necessary data entry fields used in laboratory processing through the Oracle APEX CAU application. Laboratory analysis is conducted in batches of 25 CAU units and is conducted according to the Standard Operating Procedure (URL 5). All weights are entered digitally using an analytical balance to avoid data entry errors with such precise measurements (up to 3 decimal places). Once all steps of processing have been completed, all data entry fields in the Oracle CAU Application are verified as accurate and complete, then final calcification rates per unit are calculated. Data are then extracted from the Oracle database and distributed to the NOAA ocean data archive by region and year of recovery.

The NOAA National Coral Reef Monitoring Program (NCRMP) details a long-term, ecosystem-scale approach for assessing coral reef climate, fish, benthic, and socioeconomic variables in a consistent and integrated manner. NCRMP coordinates various NOAA Coral Reef Conservation Program (CRCP) biological, physical, and human dimensions activities into a cohesive NOAA-wide effort. Through the implementation of NCRMP, NOAA is 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.
NCRMP provides a framework for conducting sustained observations of biological, climate, and socioeconomic indicators at 10 priority coral reefs across the U.S. and its territories. This integrated approach consolidates monitoring of coral reefs under a uniform method in the Pacific, Atlantic, Caribbean, and the Gulf of Mexico. NCRMP is funded by the CRCP and the NOAA Ocean Acidification Program (OAP), and supported by NOAA Fisheries, NOAA National Centers for Coastal Ocean Science (NCCOS), NOAA's Atlantic Oceanographic & Meteorological Laboratory (AOML), NOAA Coral Reef Watch, and many other partners.
The Pacific Islands Fisheries Science Center (PIFSC), Ecosystem Sciences Division (ESD) at NOAA Fisheries leads in-situ NCRMP climate monitoring in the U.S. Pacific Islands Region (formerly under the Pacific Reef Assessment and Monitoring Program [RAMP]). The climate component of NCRMP in the Pacific provides a comprehensive view of climate change impacts on coral reef ecosystems and helps identify areas of resilience and vulnerability. The key indicators used to identify and monitor climate-driven trends include 1) thermal stress caused by changes in sea temperature, 2) ocean acidification resulting from changes in carbonate chemistry, and 3) associated ecological impacts on carbonate accretion rates, erosion, and benthic community structure. ESD scientists work closely with CRCP and partners during annual Pacific NCRMP missions to deploy oceanographic (subsurface temperature recorders) and ecological (calcification accretion units [CAUs] and bioerosion monitoring units [BMUs]) instruments at fixed sites in the Pacific Ocean and conduct CTD casts and water sampling to evaluate coral reef environments. The in-situ data and satellite-based observations are also used in modeling efforts. Innovative analysis techniques are used to develop products that provide scientists, managers, decision makers and the public a better understanding of a region's resources and how they are changing over time.

dataset
Accuracy
Prior to processing the calcification accretion unit (CAU) samples, laboratory analysts are trained to properly use relevant lab equipment (analytical balance, vacuum filtration pump, etc.) and are familiarized with the data entry tool/spreadsheet. Laboratory analysts are also required to go through the CAU Processing Standard Operating Procedure and other training materials.
Completeness Measure
Calcification Accretion Units (CAUs) that have been deployed may not have been recovered due to logistical constraints of the following mission or could not be found when divers returned to the site. This can be quantified by comparing the number of recovered units to the number of units originally deployed (5 units per site). Additionally, units not recovered/found in prior missions may have been recovered in subsequent missions, evident from the deployment and recovery information in the dataset (i.e., Days In Water ~6 years instead of the standard 3 years).
Completeness Report
The calcification rate and ratio of calcified materials to fleshy materials are determined for each Calcification Accretion Unit (CAU) recovered by the PIFSC Ecosystem Sciences Division (ESD). Scripps Institution of Oceanography (Scripps) staff may conduct additional analyses of specific units to determine functional group coverage and to determine species recruitment rates based on the results of analyzed photos collected during the unit recovery and disassembly process.
Additionally, data from the CAUs processed in 2012 that do not meet the processing criteria set in 2012—that is, if the difference between the final two subsequent dry weights exceeds 0.2 grams, then those data have been omitted from the final dataset described herein.
Conceptual Consistency
The sampling procedure is based on the protocols developed by Price et al. 2012. While this project followed the same overall protocols, slight modifications were made after the first set of recovered Calcification Accretion Units (CAUs) were processed in 2012. Specifically, the following changes were implemented in 2013: 1) camera settings (adjusted to fit laboratory light conditions), and 2) use of freshwater in lieu of seawater during plate photo-documentation (seawater was not readily available in the new facility). Further, the processing procedures were also modified in 2013 such that the acceptable criteria for samples to be considered completely dry was set to 0.1 grams instead of 0.2 grams—that is, if two subsequent dry weights do not fall within the identified acceptable range (0.1 grams), the drying process continues until this criteria is met.
Assembled calcification accretion units (CAUs) are attached to the benthos using stainless steel threaded rods. Five CAUs are deployed in roughly 15m depths at permanent monitoring sites established by the NOAA Fisheries, Ecosystem Sciences Division. Calcareous organisms, primarily crustose coralline algae and encrusting corals, recruit to these CAUs and accrete/calcify carbonate skeletons over 3 year deployments. Once recovered from the seafloor, the CAUs are processed to provide estimates of net calcification. CAUs have been deployed and replaced at existing, long-term monitoring sites during National Coral Reef Monitoring Program (NCRMP) cruises, in accordance with protocols developed by Price et al. 2012.
CALCIFICATION ACCRETION UNIT (CAU) ASSEMBLY, DEPLOYMENT and RECOVERY
CAUs are composed of two 10 x 10 centimeter (cm) flat, square, gray PVC plates, stacked 1 cm apart.
Five CAU units are deployed per site on individual stainless steel stakes driven into the substrate. The units are deployed in a clustered group with the spacing between each unit being 0.5 to 5 meters. CAU sites are situated at an average depth of 15 meters. Units are placed so the CAU plates are ~10 cm above the surface substrate and the top of the CAU plate is parallel to the surface of the water.
CAU units are recovered from the seafloor 3 years after deployment (In some cases longer). Refer to the data files for the individual CAU site to determine the exact deployment time of a specific unit.
Refer to the Calcification Accretion Unit (CAU) Assembly, Deployment, and Recovery Standard Operating Procedure (2015) for a detailed description of the protocols.

CALCIFICATION ACCRETION UNIT (CAU) LABORATORY ANALYSIS
Once CAU units are recovered they are disassembled and each plate is rinsed with saltwater to remove loose sediment, sand and mobile fauna. The plates are photographed and individual images are captured of the Upper Plate, Top Side; Upper Plate, Bottom Side; Lower Plate, Top Side; Lower Plate, Bottom Side. These images can be analyzed to determine benthic composition on each plate surface. If pieces of calcified material fall off during the photographing process, the pieces are retained with the plate for the dissolution process.
After the plates have been photographed they are rinsed with fresh water and placed on a pre-weighed drying plate along with any dislodged pieces, and left to begin drying at room temperature for 24 hours and TO allow excess water to be removed. The drying plate assembly is then placed in the oven to dry at 60 degrees Celsius. If the difference in weights is less than 0.2 grams, the plates are considered dry and no further drying/weighing is required. If the difference in weights is greater than 0.2 grams the drying/reweighing process is repeated for as many 24-hour cycles as needed to obtain a difference of less than 0.2 grams. It should be noted that since the initial sample processing in 2012, the standard weighing protocol has since been improved such that the acceptable weight difference is 0.1 grams.
Once the plates are dry, each plate is placed in 5% Hydrochloric Acid (HCl) solution to dissolve the calcium carbonate materials. The plate is scraped to remove all materials and rinsed with the 5% HCl solution. The plate is then placed in the oven at 60 degrees Celsius to dry for 24 hours before the dry plate is obtained. Through the entire dissolution process all 5% HCl rinse solution is preserved for later filtering.
The 5% HCl rinse process is repeated on all materials removed from the plate until the dissolution process has stopped and all calcium carbonate material has been removed. The fleshy material and used 5% HCl rinse materials are then separated using a vacuum filtration pump by pouring the solution into a Buchner funnel, mesh layer and pre-weighed filter paper. The filter paper and fleshy material are then dried and weighed to determine the weight of fleshy algae present on each plate. The weight of calcified materials on each plate is determined by difference, where the initial weight of the dried plate (prior to the dissolution process) minus the fleshy material weight equals the weight of carbonate material dissolved. The resulting calcification rates are reported in units of grams/area/time.
Refer to the Calcification Accretion Unit (CAU) Laboratory Analysis Standard Operating Procedure (2015) for a detailed description of the protocols.
