The influences of diurnal variability and ocean acidification on the bioerosion rates of two reef-dwelling Caribbean sponges, including buoyant weight measurements and tank pH conditions from 2021-06-14 to 2021-07-20 (NCEI Accession 0260004)

Published by NOAA National Centers for Environmental Information | National Oceanic and Atmospheric Administration, Department of Commerce | Catalog Last Checked: August 03, 2026 at 04:12 AM | Dataset Last Updated: September 23, 2022 at 12:00 AM
We evaluated the influence of diurnal carbonate chemistry variability on the bioerosion rates of two Caribbean sponges: the zooxanthellate Cliona varians and azooxanthellate Cliothosa delitrix. Sponge samples were exposed to four precisely-controlled pH treatments: contemporary static (8.05 ± 0.00; mean pH ± diurnal pH oscillation), contemporary variable (8.05 ± 0.10), future OA static (7.80 ± 0.00), and future OA variable (7.80 ± 0.10). Tank pH conditions measured throughout the entirety of the experiment are provided in the "fullExperiment_pHData.xlsx" file. Significantly enhanced bioerosion rates, determined using buoyant weight measurements, were observed under more variable conditions in both the contemporary and OA scenarios for C. varians, whereas the same effect was only apparent under contemporary pH conditions for C. delitrix. Buoyant weight data is provided in the "Buoyant_Weight_Data_Submission.xlsx" file.
