Aragonite precipitations rates of precipitations from seawater, using a pH stat titrator using the constant composition technique between September 2021 and December 2022. Aragonite precipitation rates are estimated from the rate of titrant dosing. Data were collected to determine how changes in the calcification fluids of calcareous organisms affect aragonite precipitation. Data were collected by Giacomo Gardella and Nicola Allison and interpreted by Giacomo Gardella, Cristina Castillo Alvarez, Nicola Allison, Adrian Finch, Kirsty Penkman, Roland Krӧger and Matthieu Clog.

Boron isotope and trace metal measurements of fibrous aragonite in modern deep-sea coral Desmophyllum dianthus and associated CDIAC (Carbon Dioxide Information Analysis Center) hydrographic data. Atlantic Ocean, Pacific Ocean, Southern Ocean

Amino acid compositions of coral skeletons from 4 massive Porites spp. genotypes (G4, G5, G6, G7) cultured in an aquarium at seawater pCO2 of 180, 260, 400 and 750 µatm and at seawater temperature of 25 and 28°C. Protein was extracted from the skeletal samples and hydrolysed to individual amino acids. Data were collected to determine how environmental conditions influence coral skeletal biomolecules. Data were collected between August 2020 and December 2022 by Celeste Kellock, Cristina Castillo Alvarez, David Evans and Nicola Allison and interpreted by Celeste Kellock, Cristina Castillo Alvarez, David Evans, Nicola Allison, Adrian Finch, Kirsty Penkman, Roland Kröger, and Matthieu Clog.

This dataset contains video (841 mp4) and photograph (8674 jpg) data of soft and hard coral communities from Thailand, Japan and Fiji. These data were collected in order to be used to construct 3d models of the coral forests and reefs. The 3D models were creating by extracting stills from the video, and supplementing with added photographs, then using Agisoft metashape to make the photogrammetric reconstructions of the coral communities (as *.psx files). These data will be used to reconstruct the community ecology using spatial point process analyses and Bayesian network inference. There are 128 models from 8 sites taken across 25 days from Phi Phi Islands, Phuket, Thailand. The Thailand models consist of videos taken with a variety of different techniques, and were an exercise in honing the methods of data collection, rather than taking data to be used. There are 14 models from four sites in Okinawa and Shikoku Islands, Japan across 4 days. There are 47 models from nine sites in Rainbow Reef, Tavenui, Fiji across 13 days. This data set is part of an project to understand the eco-evolutionary dynamics of early animal communities using ecological approaches with this data providing modern analogue communities.

Strontium/calcium, magnesium/calcium, lithium/calcium and boron/calcium ratios of 107 aragonite samples precipitated in vitro using a pH stat titrator using the constant composition technique between August 2020 and April 2022. Measured seawater pH and dissolved inorganic carbon concentrations (DIC) are used to estimate the seawater aragonite saturation state (O) of each precipitation. Aragonite precipitation rates are estimated from the rate of titrant dosing. The trace element contents of the solid produced in the experiment was corrected for the composition of the seed used as a surface for aragonite growth. Seawater [Sr], [Mg], [Li], [B] and [Ca] were also measured and seawater [B(OH)4-] is estimated from total seawater [B] and pH. Data were collected to determine how changes in the calcification fluids of calcareous organisms affect aragonite precipitation. Data were collected by Cristina Castillo Alvarez and Ed Hathorne and interpreted by Cristina Castillo Alvarez, Nicola Allison, Adrian Finch, Kirsty Penkman, Roland Kröger, Ed Hathorne and Matthieu Clog.

Four datasets for NERC grant NE/J023329/1, Paluma Shoals reef complex, Halifax Bay, central Great Barrier Reef, Australia. DATASET 1: Single Beam acoustic survey data. This dataset comprises the single beam acoustic data that was collected from transects across the Paluma Shoals reef complex, Halifax Bay, central Great Barrier Reef, Australia. The dataset comprises of depth measurements (m) and the latitudinal and longitudinal coordinates of 58,255 point samples across the study area. The dataset was used to construct Figure 1C in Morgan, K. M., Perry, C. T., Smithers, S. G., Johnson, J. A., & Daniell, J. J. (2016). Evidence of extensive reef development and high coral cover in nearshore environments: implications for understanding coral adaptation in turbid settings. Scientific Reports, 6. DATASET 2: Paluma Shoals core data (sedimentology and palaeoecology This dataset includes all collected sedimentary and coral palaeoecological data collected from cores from across the Paluma Shoals Reef Complex, Halifax Bay, central Great Barrier Reef, Australia. This includes 1) a list of the cores recovered, their geographic location and their depths; 2) data on the mud and carbonate content of the sediment matrix from each core; 3) grainsize data from each core; 4) data from thin section analysis from each delineated facies in cores; and 5) downcore data on coral constituent abundance. DATASET 3: Core radiocarbon dates This dataset comprises the radiocarbon dates obtained from coral samples from cores collected across the Paluma Shoals Reef Complex, Halifax Bay, central Great Barrier Reef, Australia. Dates are from the NERC Radiocarbon dating lab (SUERC) in East Kilbride. DATASET 4: Benthic video imagery This dataset comprises screen grab images collected along towed transects across the Paluma Shoals reef complex, Halifax Bay, central Great Barrier Reef, Australia. Each image has the relevant lat, long coordinates printed on the top right hand corner. The sites names (folders) relate to the sites described in the following paper: Morgan KM, Perry CT, Smithers SG, Daniell JJ and Johnson JA (2016) Extensive reef development within the “mesophotic” nearshore Great Barrier Reef: Evidence for intra-regional variations in coral resilience.
