NCCOS Assessment: Digitized histological slides for stony coral tissue loss disease (SCTLD) development in Colpophylia natans, Montastrea cavernosa, Orbicella faveolata, and Orbicella franskii colonies located in the Dry Tortugas, 2021-09-01 to 2022-09-01

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 08:13 AM | Dataset Last Updated: September 11, 2025 at 12:00 AM
This digitized histological slide collection includes tissue biopsies from wild colonies of Colpophylia natans (CNAT), Montastrea cavernosa (MCAV), Orbicella faveolata (OFAV), and Orbicella franskii (OFRA) located at three sites throughout the Dry Tortugas and collected at four time points to capture pre-disease and endemic disease states (September 2021, February 2022, June 2022, and August 2022). Slides were stained with either hematoxylin and eosin stains to highlight tissue morphology or Movat’s pentachrome stain to differentiate connective tissues (mucin, collagen, elastin, myosin). All slides were scanned on a digital slide scanner to a maximum magnification of 40x. All images are in an .svs format. This dataset only includes the raw histological slide collection and associated metadata from biopsied coral colonies. Results from the analysis of the histological slides will be available from partner labs in separate associated datasets.
