National Coral Reef Monitoring Program: Erosion data from bioerosion monitoring units (BMUs) deployed at coral reef sites in the Hawaiian Archipelago from 2013-08-03 to 2016-09-25 (NCEI Accession 0173209)
Ocean Acidification (OA) is expected to reduce the calcification rates of marine organisms, yet we have little understanding of how OA will manifest within dynamic, real-world systems, nor how to accurately measure said manifestation. The term bioerosion refers to the biological destruction of hard structures, such as coral skeletons. On coral reefs, this process is the antithesis of coral calcification. If rates of bioerosion are higher than calcification, healthy reef habitats can erode into rubble and sand.
The erosion rates provided in this data set were collected from bioerosion monitoring units (BMUs) retrieved at existing long-term monitoring sites during NOAA Pacific Islands Fisheries Science Center (PIFSC), Coral Reef Ecosystem Program (CREP) led NCRMP missions around the Hawaiian Archipelago.
This archive package contains BMU data from permanent long-term monitoring sites in the Hawaiian Archipelago that were analyzed at NOAA’s Atlantic Oceanographic and Meteorological Laboratory (AOML), as part of the NOAA National Coral Reef Monitoring Program (NCRMP). BMUs are constructed from clean coral skeletons and left on the reef for a period of 3 years. This set of data is the first run of BMUs that has ever been produced, and as such, the protocol established at the time was shortly thereafter amended in order to give a more thorough picture of bioerosion rates. Early analysis procedures utilized a benchtop micro computed tomography scanner (microCT, Bruker) for initial scans (pre-deployment), while post collection analyses (including those in this submission) were analyzed by a larger Computed Tomography device (CT scanner, Siemens). Additionally, this is the only set of BMUs that were created from Isopora sp., due to material availability at the initiation of this project.
BMUs are CT scanned for changes in density, volume and mass in which rates of bioerosion can be assessed. Annual erosion and accretion rates can be determined from these data in terms of loss of reef structure volume as well as mass in grams of calcium carbonate. Accretion rates given in this data set were determined by finding the volume of non-original carbonate material found on the external surface of the BMUs divided by the number of years the BMU was deployed on the reef. These rates can detect accretion signals when calcifying organisms, such as corals or algae, have grown on their exteriors. Rates of macroboring were determined by changes in the internal volume of the BMUs (e.g., that removed by bore holes) divided by the number of years the BMU was deployed on the reef. Macroboring can occur from eroders such as, clionaid sponges, annelids and other macroboring fauna.
Grazing and microboring rates are not provided in this data set because pre-volume measurements were not collected due to changes in methodologies, however, subsequent datasets will contain these data.

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 bioerosion time series data—along with other data collected at the survey sites (archived separately under NCRMP)—are used to help scientists assess and understand how coral reefs monitored by the NOAA Coral Reef Ecosystem Program (CREP) are responding to ocean acidification. |
