| log in | [Incubation Data] - Coral physiological and biological data collected during acute exposures in static incubation chambers in Hawaii from June 2023 to January 2025 (Collaborative Research: Reevaluating calcification response to changes in seawater chemistry by testing the Proton Flux Hypothesis and the Coral Metabolism Model) | This dataset contains carbonate chemistry, physiological response, and incubation measurements from controlled static incubations of two Hawaiian coral species, Montipora capitata (branching and plating morphologies, urn:lsid:marinespecies.org:taxname:287697) and Pocillopora acuta (urn:lsid:marinespecies.org:taxname:759099). Corals were exposed to a series of experimental seawater chemistry treatments designed to independently manipulate proton concentration and carbonate ion availability through adjustments to total alkalinity and dissolved inorganic carbon. Treatments spanned ambient conditions as well as elevated and reduced total alkalinity, elevated and reduced pH, and combinations of altered pH and alkalinity. For each treatment, seawater parameters were measured, including temperature, salinity, dissolved oxygen, pH on the total scale, total alkalinity, bicarbonate, carbonate ion concentration, pCO2, dissolved inorganic carbon, and aragonite saturation state. Coral incubations were conducted under static conditions to quantify changes in carbonate chemistry associated with coral metabolic activity and to assess species- and morphology-specific calcification responses across distinct carbonate system states. This dataset supports the evaluation of the Proton Flux Hypothesis and Coral Metabolism Model by providing detailed carbonate chemistry conditions and coral responses across a spectrum of experimentally generated seawater states.\n\ncdm_data_type = Other\nVARIABLES:\ndate (unitless)\nspecies (unitless)\ntreatment (unitless)\ncondition (unitless)\ngenotype (unitless)\ntime_elapsed (Time, hours)\ntemp (degrees Celsius (degC))\ndo_mg_l (milligrams per liter (mg/L))\nsal (parts per thousand (ppt))\nph_nbs (NBS scale)\nph_mv (millivolts (mV))\nbwt (grams (g))\n...

| log in | [Mesocosm Experiments: Buoyant weights] - Buoyant weight data collected during acute and chronic stress exposures in outdoor mesocosms in Hawaii from January 2022 to March 2024 (Collaborative Research: Reevaluating calcification response to changes in seawater chemistry by testing the Proton Flux Hypothesis and the Coral Metabolism Model) | Coral buoyant weight data collected from Montipora capitata (urn:lsid:marinespecies.org:taxname:287697) and Pocillopora acuta (urn:lsid:marinespecies.org:taxname:759099) during acute and chronic stress exposures in outdoor mesocosms in Hawaii from January 2022 to March 2024.\n\nThis dataset includes demographic data (date measure was taken, experiment number, time point, season experiment was conducted in, treatment, mesocosm number, species code, coral individual) and corresponding buoyant weight value. \n\nStudy description (discusses related data collected during the experiment):\nThis project examined the fundamental connections between seawater chemistry and coral physiology by investigating the modulation of seawater chemistry in the microenvironment surrounding corals. Coral biological response variables were quantified during short-term incubations and long-term mesocosm manipulations to understand physiological implications across multiple scales (i.e., individual and community scales) and across boundary layers. This project generated several datasets to investigate coral response (biological and physiological), community response (ecosystem), environmental characteristics (water quality and seawater chemistry), and calibration data for quality control and standardization (see \"Related Datasets\" and \"Supplemental Files\" sections). All datasets are provided in .csv format for broad-scale accessibility and use. All biological data includes demographic variables to describe the experiment (experiment number, season experiment was conducted in, mesocosm number coral was held in, species code, coral individual number, and time point), while all water data includes a different set of demographic data (experiment number, season experiment was conducted in, and date measurements were taken). All datasets are organized in tidy format with each row equating to a single measurement and each column a separate variable.\n\ncdm_data_type = Other\nVARIABLES:\ndate (unitless)\nexperiment (unitless)\ntp (unitless)\n...
