The newly developed USGS Coral Core Archive, housed at the Santa Cruz and St. Petersburg Coastal and Marine Science Centers, contains approximately 500 coral reef cores from U.S. jurisdictions worldwide.

Example of the relationship between CT intensities and measured density of the coral standards used to calibrate data. The measured density of the coral standards are compared to the mean intensities of each standard. Linear regressions calculated from the standard values are then used to calibrate data.

Photo of coral carbonate standards, arranged from high to low density. To convert CT values to real-world densities and quantify the uncertainty in reconstructed density as a result of offsets, a set of carbonate standards are included in every CT scan that represent a range of coral species with different densities.

Time-averaged images, which represent the time-mean of all the images collected during a video, are used to identify areas where waves are breaking, which show up as bright white bands in the image.
