Coupled Mg/Ca - D47 isotope data on foraminifera and calibration samples (NERC grant NE/M003752/1)

We used existing coretop samples from several sites from the Atlantic, Arctic, Pacific, and Indian Oceans (Fig. 1 and Table S1) to test the relationship between Mg/Ca ratios and D47 values in modern foraminifera. In the North Atlantic the cores were the same as those used previously by Elderfield and Ganssen (2000) (Tables S1 and S2). Coretops with the potential to yield large (>5 mg) mono-specific samples of foraminifera were selected from the >300 lm size fraction of the sediment except for Neogloboquadrina pachyderma (sinistral) where the >150 lm size fraction was chosen to obtain sufficient material. After cleaning the samples consisted of _3 mg of foraminiferal calcite and included 8 different species of surface- and deepdwelling planktonic foraminifera: Globigerina bulloides, Globigerinoides sacculifer, Globorotalia hirsuta, Globorotalia inflata, Globorotalia menardii, Neogloboquadrina dutertrei, Neogloboquadrina pachyderma (s), and Orbulina universa. The Godwin Laboratory clumped isotope calibration (i.e., the regression between D47 and temperature) was established using natural cave carbonates that precipitated subaqueously at known temperatures, ranging from 3 to 47ºC (Table 1, Fig. 2). These carbonates grew under conditions that minimize CO2-degassing and evaporation and hence kinetic fractionation effects are negligible owing to an unlimited DIC pool in the water (Kele et al., 2015). All samples consist of calcite, except NAICA-1 which is aragonite.

FIB-SEM and X-ray micro-tomographic images of carbonate rock dissolution during reactive CO2-saturated brine injection under reservoir conditions

The datasets contain FIB-SEM and X-ray micro-tomographic images of a wettability-altered carbonate rock sample before and after dissolution with reactive CO2-saturated brine at reservoir pressure and temperature conditions. The data were acquired with the aim of investigating CO2 storage in depleted oil fields that have oil-wet or mixed-wet conditions. Our novel procedure of injecting oil after reactive transport has revealed previously unidentified (ghost) regions of partially-dissolved rock grains that were difficult to identify in X-ray tomographic images after dissolution from single fluid phase experiments. The details of image files and imaging parameters are described in readme file.

Planktonic foraminiferal census counts and counts of Ice Rafted Debris (IRD) from sediment samples collected during Ocean Drilling Programme (OPD) leg 162 site 983 (NERC grant NE/L006405/1)

These data are described fully in the following publication: S. Barker, J. Chen, X. Gong, L. Jonkers, G. Knorr, D. Thornalley, Icebergs not the trigger for North Atlantic cold events. Nature 520, 333-336 (2015). The dataset comprises planktonic foraminiferal census counts and counts of Ice Rafted Debris (IRD) from sediment samples collected during Ocean Drilling Programme (OPD) leg 162 site 983 in the Northeast Atlantic (60.48°N, 23.68°W, 1,984m water depth). The data were collected between Jan 2011 and Dec 2014. The dataset includes values every 2cm from 2 to 51.5m (metres composite depth) along the ship-board splice. Before counts were performed bulk sediments were spun overnight in distilled water, before sieving over a 63µm sieve. All portions were dried, weighed and stored. Counts were performed on a split of the >150µm fraction. The dataset can be employed to assess changes in surface temperature and presence of rafted ice over the site over the past 440kyr or so. This information is of interest to paleoceanographers and paleoclimatologists. The dataset was created and interpreted by a team at Cardiff University, with additional input from other authors named in the publication. The dataset is complete except for one or two samples that were not received from the repository.

IODP Expedition 352 (Bonin Forearc) Pb isotope data (NERC grant NE/M012034/1)

We provide here Pb isotope data for the basement rocks cored during IODP Expedition 352 (Bonin Forearc). The data are reported as 206Pb/204Pb, 207Pb/204Pb and 208Pb/204Pb ratios together with their errors. The overall accuracy of the data was determined using international standard NBS SRM 981. Values for this standard achieved during the measurement period were 206Pb/204Pb = 16.9404 ±32,207Pb/204Pb = 15.4969 ±32, 208Pb/204Pb = 36.7149 ±90 (2sd; n=44). The data are separated into four parts one for each drill site that cored basement. Sites 1440B and 1441A both sampled a basalt type known as FAB (Forearc Basalts), whereas Sites 1439C and 1442A both sampled boninites (Mg-rich andesites). Both rock types are typical of the forearc setting and contain information needed to understand the process of subduction initiation. A summary of the Expedition, and hence the petrography and setting of the samples as well as the various scientific objectives for the project to which these analyses contribute) may be found in: Reagan, M.K., Pearce, J.A., and Petronotis, K., Expedition Scientists, 2015, Izu-Bonin-Mariana Fore Arc: Proceedings of the International Ocean Discovery Program, 352.

Groundwater vulnerability data for Wales

The Environment Agency and Natural Resources Wales have updated its groundwater vulnerability map to reflect improvements in data mapping, modelling capability and understanding of the factors affecting vulnerability. Two new maps are available which show the vulnerability of groundwater to a pollutant discharged at ground level. The potential impact of groundwater pollution is considered using the aquifer designation status which provides an indication of the scale and importance of groundwater for potable water supply and/or in supporting baseflow to rivers, lakes and wetlands. This dataset for Wales has shared intellectual property (IP) between Natural Resources Wales and British Geological Survey.

Experimental and numerical data for "Characterising Drainage Multiphase flow in Heterogeneous Sandstones" by Jackson, Krevor et al, 2018

The data presented here contains the experimental X-ray CT dataset used for the paper "Characterising Drainage Multiphase flow in Heterogeneous Sandstones" by Jackson, Krevor et al (DOI 10.17605/OSF.IO/WCXNY), along with CMG IMEX modelling files. Core averaged pressure data and saturations, along with 1D saturation profiles are available in the supporting information fle. CT data is provided in the four '..._scans' folders. These contain reconstructed .dicom tomographs from X-ray CT imaging with native resolution 0.234375mm x 0.234375mm. The image thickness is 5mm for the Bentheimer and 3mm for the Bunter. Each files contains 3x scans for each fractional flow. Dry, water, brine equilibrated with CO2 (labelled SW), nitrogen and CO2 background scans are also provided, which are obtained after single phase core flooding. CMG IMEX .dat files contain the necesary input files for CMG IMEX to run the numerical core flood simulations (the low flow rate core flood examples are included). These have associated .inc files for the 3D capillary pressure scaling (the end point of the capillary pressure curve at irreducible water saturation) and the 3D porosity map. These are read into the simulation files on execution. The porosity and capillary pressure files are for the final, full length rock cores used to produce the main figures in the paper (Figure 5 onwards). The outputs from the CMG IMEX simulation can be read into the 3D results viewer where 3D saturations and pressure drops are obtained. This work was funded by the Natural Environment Research Council (Grant number: NE/N016173/1).

Modelled depth and thermal history for sediments offshore Sumatra (NERC grant NE/P012140/1)

The thermal state of marine sediments controls a range of potential dehydration reactions as sediments are subducted. In thick sediment sections it is possible that reactions that would normally occur within a subduction zone start offshore of the deformation front. This scenario may be occurring at the Sumatra subduction zone (e.g. Geersen et al., 2013; Huepers et al., 2017). We have investigated this possibility by modelling the thermal and depth history of sediments offshore Sumatra. We have used a range of different assumptions about how the sediments decompact with depth, as well as testing the dependence on the seismic velocities used for depth conversion of the horizons.
