The dataset includes oxygen and carbon stable isotopes measured on multispecies planktonic foraminifera from 15 million years ago to the present, as well as trace elements ratio and abundance counts. For the code availability and instructions to run the cGENIE version and experiments see Boscolo-Galazzo, Crichton et al. (2021).

The data set encompasses the data generated through the 8 experimental runs on the 25 kWth calcium looping pilot plant at Cranfield University arranged into 8 functional Excel spreadsheets. The operational data are gathered by the acquisition with Labview software (the composition of the gas from the calciner and carbonator; temperatures of the electrical furnaces on the preheating lines and around the calciner; temperatures of the gas in the preheating lines and in the calciner) and Pico software (temperatures in the carbonator and lower loop seal and pressures in the calciner and in the carbonator). Moreover, the data from the experimental diary (inputs of gasses and solids into the rig) and the data from the post-processing of the extracted solids are included. All the data are combined into comprehensible charts that describe and explain the experimental runs together with the mass and energetic model of the system during steady state operations.

Mg/Ca in multiple species of planktonic foraminifera from five time slices since the Middle Miocene to present (target ages 15, 12.5, 10, 7.5, 4.5, 2.5 and 0 Ma). These samples are from a range of globally and latitudinally distributed DSDP (Deep Sea Drilling Program), ODP (Ocean Drilling Program), IODP (International Ocean Discovery Program) open ocean sites. From low to high latitudes these are: Site U1338, U1489 (Eastern and Western Equatorial Pacific), Sites 871, 872, and Site U1490, (Western Tropical Pacific), Site 242 (Mozambique Channel, Indian Ocean), U1482 (Australian Continental Margin), Site 516 (Western Atlantic Ocean), Site 1138 (Kerguelen Plateau, Southern Ocean). The Mg/Ca ratios were measured using Inductively coupled mass spectrometry (ICP-MS) at Cardiff University between December 2018 and June 2019. The data were collected to explore Mg/Ca values for modern and extinct species at different intervals of time (which were different climatically) and at different geographical locations. This data was collected by E.Mawbey as part of a project funded by NERC (Q10 project) to investigate changes in foraminiferal depth habitat in response to different climate conditions.

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.

This dataset represents the first publication of complete national maps from the Geochemical Baseline Survey of the Environment (G-BASE) and TellusNI projects, whose aim was to conduct a national geochemical survey of the United Kingdom in order to improve understanding of our geology and environment and provide quantitative evidence against which to gauge future environmental change. This dataset consists of a series of interpolated raster (ASCII grid) maps displaying the concentrations of a suite of chemical elements (and oxides) in the stream sediments of the United Kingdom. The chemical elements are as follows: Arsenic, Barium, Calcium (CaO), Chromium, Cobalt, Copper, Iron (Fe2O3), Lanthanum, Lead, Magnesium (MgO), Manganese (MnO), Nickel, Potassium (K2O), Rubidium, Uranium, Vanadium, Zinc and Zirconium.

The London Earth data are part of the Geochemical Baseline Survey of the Environment (G-BASE) dataset, a nation-wide project to determine the distribution of chemical elements in the surface environment. London Earth focuses on the soil of the capital city, the limits of the survey being defined by the Greater London Authority (GLA) administrative boundary. Chemical elements have been determined by X-ray fluorescence spectrometry (XRFS) at the laboratories of the British Geological Survey (BGS) in Keyworth, Nottingham. These results are presented as a Microsoft Excel file.
