This UKCCSRC (UK Carbon Capture and Storage Research Centre) Call 1 project involved the development, testing and validation of a two-fluid transient flow model for simulating outflow following the failure of high pressure CO2 pipelines is presented. The project made use of experimental data and used experimental data available from other UK/EC funded projects. The model developed accounts for thermal and mechanical non-equilibrium effects during depressurisation by utilising simple constitutive relations describing inter-phase mass, heat and momentum transfer in terms of relaxation to equilibrium. Pipe wall/fluid heat exchange on the other hand is modelled by coupling the fluid model with a finite difference transient heat conduction model. This paper describes the model, the details of its numerical solution and its validation as well as parametric analysis of relevant parameters. http://www.sciencedirect.com/science/article/pii/S1750583614002394, DOI: 10.1016/j.ijggc.2014.08.013.

These data are the recorded outcomes of binary male choice experiments. Teleopsis dalmanni males were able to choose to mate with either a large or a small female. Individuals were taken from laboratory stock populations. Also included is information on male genotype indicating if he is a carrier of a sex-ratio distorting or nondistorting X chromosome, and a calculation of male preference. The second dataset additionally contains measures of male eyespan and thorax length obtained by measuring images.

The raw data contain genotype information for offspring collected from controlled crosses of Teleopsis dalmanni. Parents were taken from laboratory stock populations. Offspring genotypes were assigned by sizing a microsatellite, which distinguishes sex-ratio distorting and nondistorting X chromosomes. Also included is information on offspring sex and food treatment. The processed data summarises genotype counts by collection date and cage id (date/food treatment/cage). Also included is a fitness calculation for each genotype in each cage. Full details about this nonGeographicDataset can be found at https://doi.org/10.5285/71529a64-6c1b-4c8f-ae3f-7c4870efd976
The data contain phenotype measures of Teleopsis dalmanni males. Individuals were all taken from a laboratory stock population. Individuals carried either a nondistorting wildtype X chromosome or a sex-ratio distorting X chromosome. Data were obtained by measuring images of testes, accessory glands, thorax and eyespan, and direct counts of fertilised (hatched) and unfertilised egg.

Synchrotron X-radiography (images) and diffraction data collected to measure rheology of Quartz coesite and stishovite.
This dataset contains VASP runs performed on ARCHER to calculate the electrical and thermal conductivities of pure iron and iron alloys at Earth's core conditions using density functional theory with the Kubo-Greenwood formulation. Data are available for both the solid and the liquid phase characterising the inner and outer core respectively. Also included in the dataset the runs for computing the lattice contribution to the electrical resistivity of magnetic bcc iron at ambient pressure and two low temperatures and for computing the melting curve of fcc nickel. These data were also used for the modelling of the geodynamo and the thermal history of the Earth, to calculate the transport properties for silicon-oxygen-iron mixtures and to confirm the saturation of electrical resistivity of solid iron at Earth’s core conditions. The results from this dataset showed that both conductivities are much larger than previously thought with important implications for the geodynamo and the thermal history of the Earth, benefitting the geodynamo community. The results of our research have been recently confirmed by new experimental results obtained at Earth's core conditions. Further details can be found in Alfè et al. (2012); Pozzo et al.

Monthly anomalies (August 2002 to July 2016) of total terrestrial water storage (TWS), soil moisture storage (SMS), surface water storage (SWS), snow water storage (SNS), groundwater storage (GWS) derived from an ensemble mean of 3 gridded GRACE products (CSR, JPL-Mascons and GRGS) and an ensemble mean 4 land surface models (CLM, NOAH, VIC and MOSAIC), provided by the NASA’s Global Land Data Assimilation System (GLDAS). Monthly precipitation (CRU) data, derived from the Climatic Research Unit (CRU), were aggregated over each aquifer system. GRACE, GLDAS and CRU datasets are publicly available at the global scale.

The dataset contains oxygen and carbon isotope measurements from multiple-shell samples of the ostracod Heterocypris punctata, from Core FP2 taken from Freshwater Pond, Barbuda. A chronology for the core is provided by radiocarbon dates. The data, which are further described in Burn et al. (2016) The Holocene, 26(8), 1237-47, provide a proxy for changing rainfall patterns for the period 2000-1555 CE.
