Carbon dioxide flux and isotopic composition from sedimentary rock weathering, Draix-Bleone Critical Zone Observatory, France

The measurements and data were obtained to study the release of carbon dioxide during the chemical weathering of sedimentary rocks, and how these CO2 fluxes were related to environmental parameters (temperature, hydrology). Weathering of sedimentary rocks can result in CO2 release from the oxidation of rock organic carbon oxidation, but also due to the oxidation of sulfide minerals, production of sulfuric acid and subsequent release of CO2 from carbonate minerals. The rock-derived carbon sources are understudied, and form an important part of the geological carbon cycle. The CO2 flux measurements were made on 5 rock chambers (H4, H6, H7, H8 and H13) installed in the Draix-Bleone Critical Zone Observatory, France, on outcrops of Jurassic marls. Measurements and data were collected from December 2016 to May 2019. Regular visits to the site (~4 per year) returned data on total CO2 flux (Total-CO2-flux.csv). This was explored as a function of temperature and ambient hydroclimate (precipitation). The datasets include the total CO2 flux measured at each visit to a chamber, and measurements of the internal chamber temperature. To determine the source of CO2 measured in the chambers, we trapped the CO2 using zeolite sieves and recovered it in the laboratory. The radiocarbon activity (reported as fraction modern, F14C) and its stable isotope composition (d13C) were measured from CO2 collected from chambers H4 and H6 over the sampling period (Radiocarbon-data.csv). These were used in a mixing analysis to partition the source of CO2 using a mixing model approach (Partitioned-CO2-fluxes.csv) as explained in full in the published paper Soulet et al., 2021, Nature Geoscience. We also measured the geochemical characteristics of the bedrocks being measured (rock-geochemical-composition.csv), including the organic carbon concentration, inorganic carbon concentration and their isotopic composition. Finally, we measured environmental variables of interest - the chamber temperature and the air temperature at the Draix-Bleone observatory (chamber-temperature.csv and Air-temperature-at-laval-le-plateau-weather-station.csv, respectively). This research was funded by a European Research Council Starting Grant to Robert Hilton (ROC-CO2 project, grant 678779) and radiocarbon and stable isotope measurements were funded by the Natural Environment Research Council (NERC), UK, (NERC Environmental Isotope Facility NEIF Radiocarbon Allocation 2074.1017) to Guillaume Soulet, Robert Hilton and Mark Garnett.

BGS GeoIndex - Hydrogeology data theme (OGC WxS INSPIRE)

The hydrogeological map indicates aquifer potential in generalised terms using a threefold division of geological formations: those in which intergranular flow in the saturated zone is dominant, those in which flow is controlled by fissures or discontinuities and less permeable formations including aquifers concealed at depth beneath covering layers. Highly productive aquifers are distinguished from those that are only of local importance or have no significant groundwater. Within each of these classes the strata are grouped together according to age or lithology. The 1:625 000 scale data may be used as a guide to the aquifers at a regional or national level, but should not be relied on for local information.

Marine Aggregate Sustainability Fund (MALSF) Geology and Geophysics Survey Data (2003 to 2010)

The Marine Aggregate Levy Sustainability Fund (MALSF) commissioned a series of Regional Environmental Characterisation (REC) surveys via the Marine Environment Protection Fund (MEPF) to develop understanding of submerged habitats and heritage in Britain. The aim was to acquire high quality data to enable broad scale characterisation of the seabed habitats, their biological communities and potential historic environment assets. The surveys were conducted in the following areas - Outer Bristol Chanel (2003 – 2005), Eastern English Channel (2005 – 2006), South Coast (2007 - 2010), Outer Thames (2007), East Coast (2008 - 2009), Humber (2008 - 2009). The Geology and Geophysics component of the data are archived by British Geological Survey (BGS) in the Marine Environmental data and Information Network (MEDIN) Data Archive Centre (DAC) for Geology and Geophysics. The data includes bathymetry, sidescan sonar, sub-bottom profiler, magnetometer, seabed video and photographs, Particle Size Analysis (PSA) data, vibrocore (logs and images). Data are delivered via the BGS Offshore GeoIndex www.bgs.ac.uk/GeoIndex/offshore.htm. Additional data are available on request enquiries@bgs.ac.uk. Other data types have been archived with the other MEDIN DACs as appropriate (UKHO DAC for bathymetry data and DASSH DAC for biological data). The MALSF ceased operation at the end of March 2011 (http://www.marinealsf.org.uk/).

Strategic Environmental Assessment (SEA) Data and Related Information (1999-)

The SEA portal is managed by the BGS on behalf of DECC and provides free access to downloadable data, information and reports which have been produced through the SEA process. The Department of Trade and Industry (now DECC) began a sequence of sectoral SEAs of the implications of further licensing of the UK Continental Shelf (UKCS) for oil and gas exploration and production in 1999. The SEA Process subdivided the UKCS into eight areas shown; beginning in 2008, integrated Offshore Energy SEAs have been undertaken that cover the whole UKCS. An integral part of the SEA programme has been a series of research and monitoring surveys commissioned to acquire new data about the offshore environment and used to help inform the relevant SEAs. Many files can be downloaded directly from portal. Those that are too large to download can be ordered via the website for postal delivery from BGS.

BIRPS (British Institutes Reflection Profiling Syndicate) Faeroe-Iceland Ridge Experiment (FIRE) seismic data (1994)

Faeroe-Iceland Ridge Experiment (FIRE) was acquired by BIRPS (the British Institutions Reflection Profiling Syndicate). The primary target was anomalously thick oceanic crust along the Faeroe-Iceland Ridge that was possibly formed by underplating due to the proximity of the Iceland hotspot. FIRE made use of 110 land seismometers to record the airgun shots. The resulting velocity models and reflector geometries have proved critical in interpretation of variations in crustal volumes along the ridge. The data were recorded to 23 s two-way time.

BIRPS (British Institutes Reflection Profiling Syndicate) Banda seismic data (1992-1993)

In 1992, BIRPS joined with the Indonesian Marine Geological Institute to record two long multichannel normal-incidence reflection profiles, one of which is DAMAR, the other TIMOR, and one short profile (API) close to the volcano Gunung Api. The survey provides a modern analogue to tectonics hypothesized to have occurred across the Iapetus suture zone of northern England 450-400 Ma. The Banda Arc of Indonesia near the island of Timor is widely recognized as the premier example of the active subduction of continental crust and lithosphere beneath oceanic lithosphere. The crossing of a modern island arc and close passage to active volcanoes was intended to image reflections associated with magma in the crust and uppermost mantle.

BIRPS (British Institutes Reflection Profiling Syndicate) 3DEPR-ARAD seismic data (1997)

The 3D multi channel seismic data were acquired as part of a collaborative investigation into models of magmatic segmentation between the Scripps Institute of Oceanography and BIRPS (the British Institutions Reflection Profiling Syndicate). The 3D EPR (East Pacific Rise) ARAD (Anatomy of a Ridge Axis Discontinuity) EW9707 cruise was undertaken in September and October 1997 to provide both refelction and wide-angle seismic data for the study of the overlapping spreading centre (OSC) at 9 degrees 3 minutes N on the East Pacific Rise. The data were acquired with a single source and a single streamer with a nominal line spacing of 100 m. The 3D-EPR ARAD survey was a joint NERC/NSF (US National Science Foundation) funded project and the copyright for this survey is held jointly. Reference: Bazin, S. Harding, AJ. et al.

Seismic first breaks for Syczyn seismic survey

The dataset contains condensed results of seismic refraction survey, that can be regarded as “hard data”. Data files Syczyn-1_P.ASC and Syczyn-1_S.ASC represents tables obtained for line Syczyn-1, wave P and wave S respectively; Data files Syczyn-2_P.ASC and Syczyn-2_S.ASC represents tables obtained for line Syczyn-1, wave P and wave S respectively. Each file contains 4 columns: Record No. – sequential record identifier; Source location – distance from the beginning of the line to the (current) source point (in meters); Receiver location – distance from the beginning of the line to the given receiver (in meters); First Break – delay time between emission of the wave to its arrival at the given receiver point (seconds). Dataset is formatted in simple table, that can be imported to other seismic software for modelling velocity field. Different computing algorithms generate slightly different velocity models, so it can be useful to have hard data for comparison.

Characterization of shale gas wells for well integrity simulations

The dataset is on characterization of shale gas wells for well integrity simulations. Basing on raw data and other information pertaining to two shale gas wells, acquired from Polish Oil and Gas Company (PGNiG) input to the well integrity simulations carried out by TNO was supplied by PIG-PIB. The input consisted in elaborating generalized models of the wells and their surroundings as wells as characterization of the target formations. Well construction schemes including the production casing sizes and depths and generalized lithostratigraphy of the geological formations in question were composed. Raw data acquired from PGNiG included wireline logging data (and interpretation results) together with results of laboratory measurements of drill core samples (e.g., on geomechanical properties). Regarding characterization of the target formations the most important information created were distributions of in situ stresses within particular formations in both wells, assessed on the base of results of wireline, density logging (vertical stress – based on weight of the overburden at a certain depth) and laboratory measurements of geomechanical parameters (horizontal stress – based on pressure values measured within rock sample in tri-axial chamber at reservoir conditions). Temperature values within formations in question were assessed assuming local geothermal gradient and information from PGNiG reports. The dataset was created within SECURe project (Subsurface Evaluation of CCS and Unconventional Risks) - https://www.securegeoenergy.eu/. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 764531

Formation confinement analyses based on available results of laboratory geochemical measurements of brine samples for selected sites

The dataset is on analyses on formation confinement based on available results of laboratory geochemical measurements of brine samples for several field sites (shale wells, acidic gas storage within a depleted gas field and a saline aquifer structure – a possible CO2 storage site). The goal of these analyses was to assess the presence of relic brine within reservoirs/aquifers in question or brine exchange between reservoirs/aquifers within these sites. Results of these analyses can be used to evaluate caprock integrity for they could be indirect evidence of possible migration paths (faults, fractures) and hence possible leaks within the site currently, in the not-too-distant geological past, or no migration or fluid exchange at all (relic brine). The dataset was created within SECURe project (Subsurface Evaluation of CCS and Unconventional Risks) - https://www.securegeoenergy.eu/. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under grant agreement No 764531
