  • 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

  • The dataset contains results of field measurements (temperature, pH, conductivity, redox potential, oxygen content) of groundwater and samples collection details as well as the results of laboratory analysis of the set of dissolved and gaseous parameters performed within the environmental monitoring campaign on 3 Polish shale gas sites where exploration activities including hydraulic fracturing were conducted in 2010-2016 period.

  • Data set is of drill fluid return, settling tank, and bore hole flush fluids sampled during the development of GGC01 seismic monitoring borehole and GGA07 and GGA08 mine water geothermal wells at the UKGEOS - Glasgow site.

  • Global warming during the Palaeocene-Eocene Thermal Maximum (PETM, ~56 Ma) is commonly interpreted as being driven by massive destabilization of carbon from surficial sedimentary reservoirs. If correct, this has important implications for the amplification of future fossil fuel emissions via carbon-climate feedbacks. In our study we provided new paired records of boron and carbon isotope changes in the ocean that questions this long-held interpretation. Our data are implemented in an Earth system model to reconstruct the unfolding carbon cycle dynamics across the event. Strong evidence for a larger (>10,000 PgC) and on average isotopically heavier (> -17‰) carbon source leads us to identify volcanism associated with the North Atlantic Igneous Province as the main driver of the PETM. We also find that although organic carbon feedbacks with climate played a more minor role in driving the event than previously thought, organic matter burial was important in ultimately sequestering this carbon and driving the recovery of the system. Data presented in this data set comprise geochemical elemental, as well as boron, carbon and oxygen isotopic data from surface dwelling foraminifera Morozovella Subbotina. Alongside the boron isotopic data we also provide reconstructed surface water pH with corresponding uncertainties for our preferred pH reconstruction.
