Title: National Coral Reef Monitoring Program: Calcification Rates of Crustose Coralline Algae Derived from Calcification Accretion Units (CAUs) Deployed across the Pacific Remote Island Areas since 2011
Short Name: NCRMP: CAUs PRIAs
Status: In Work
Publication Date: 2018-08
Abstract:

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 missions around the Pacific Remote Island Areas in 2014, 2015, and 2017, in accordance with protocols developed by Price et al. 2012. 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 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).

Supplemental Information:

The National Coral Reef Monitoring Program (NCRMP) is 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 will consolidate monitoring of coral reefs under a uniform method in the Pacific, Atlantic, Caribbean, and the Gulf of Mexico for the first time. NCRMP is funded by the CRCP and supported by NOAA Fisheries, NOAA National Centers for Coastal Ocean Science (NCCOS), and many other partners. The PIFSC Ecosystem Sciences Division (ESD) at NOAA Fisheries is leading ocean and climate change monitoring in the U.S. Pacific Islands Region.

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) ecological impacts by collecting data on coral growth rates, erosion, and community structure to understand the impacts of thermal stress and ocean acidification on the ecosystem. Each year, ESD scientists work closely with CRCP and partners during Reef Assessment and Monitoring Program (RAMP) missions to collect data using moored oceanographic (subsurface temperature recorders) and ecological (calcification accretion units [CAUs] and autonomous reef monitoring structures [ARMS]) instruments stationed at fixed sites in the Pacific Ocean, and water samples collected by divers. The in-situ data and satellite-based observations are also used in modeling efforts. Innovative analysis techniques are used to develop products that give fellow scientists, managers, decision makers and the public a better understanding of a region’s resources and how they are changing over time.

Data Quality

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).

Completeness Report:

The calcification rate and ratio of calcified materials to fleshy materials are determined for each Calcification Accretion Unit (CAU) recovered. 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 will continue until this criteria is met.

Quality Control Procedures Employed:

Prior to processing a batch from each region/jurisdiction, laboratory analysts inventory the recovered Calcification Accretion Units (CAUs) to ensure all units are accounted for and all serial numbers assigned to each unit match field data records. The Data Manager additionally performs quality control checks on the site deployment data and the recovery data for further accuracy. Once all CAUs from the jurisdiction have been processed, the dataset is checked by the analysts to ensure: 1) all CAU plates have been processed, 2) there are no missing cell values, and 3) calculations for net weight of calcified materials are correct. The dataset is then turned over to the Data Manager for further quality control procedures and data ingestion into the PIFSC Ecosystem Sciences Division master database.

Lineage

Lineage Statement:

Assembled calcification accretion units (CAUs) are attached to the benthos using stainless steel threaded rods. There are five CAUs deployed at each site. 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 Pacific Reef Assessment and Monitoring Program (RAMP) cruises, in accordance with protocols developed by Price et al. 2012.

Process Steps

Process Step 1

CC ID: 366675
Description:

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. 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.
