The Ocean Archive System searches our original datasets as they were submitted to us, not individual points or profiles. If you want to search and retrieve ocean profiles in a common format, or objectively analyzed fields, your better option may be to use one of our project applications. See: Access Data

Title: National Coral Reef Monitoring Program: Erosion data from bioerosion monitoring units (BMUs) deployed at coral reef sites in Flower Garden Banks National Marine Sanctuary and Salt River, St. Croix, USVI from 2015-06-01 to 2019-09-12 (NCEI Accession 0224178)
Abstract: 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 dataset were collected from bioerosion monitoring units (BMUs) retrieved at existing long-term monitoring sites during NOAA Atlantic Oceanographic and Meteorological Laboratory (AOML), Acidification, Climate, and Coral Reef Ecosystems Team (ACCRETE) led NCRMP missions in Flower Garden Banks National Marine Sanctuary and Salt River, St. Croix, USVI.

This archive package contains BMU data from permanent long-term monitoring sites in the Flower Garden Banks National Marine Sanctuary and Salt River, St. Croix, USVI 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.

BMUs are CT scanned for changes in density, volume and mass in which rates of bioerosion can be assessed using Amira analysis software (FEI). 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 dataset 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.

The Flower Garden Banks National Marine Sanctuary BMUs were initially scanned using a Bruker Skyscan 1174 microCT while post-scans where taken with a macroCT. Slight anomalies might occur with the use of two different machines. St. Croix BMU pre-scans and post-scans were taken using the macroCT so they are directly comparable.
