Sediment data and Nd data from fish teeth in samples from IODP Site 1490. NERC grant The Late Miocene Climate Enigma: Insights from Expedition 363.
Pictures of sulphides and trace element concentrations from ore minerals in the El Teniente porphyry Cu-Mo deposit, Chile. Samples were picked for analysis from the Natural History Museum London’s ore collection. This data contains petrological photographs and trace element concentration of ore minerals. This data was collected as part of the TeaSe consortium NERC grant in order to determine the concentration and hosting of critical and precious metals in various types of ore deposits and barren rocks from different geological environments. This data was collected and interpreted by researchers at Cardiff University.
Geochemical and field data collected from samples from ore deposits hosted in the Troodos ophiolite, Cyprus by Dr Andrew Martin during his PhD. File T1 contains sample names, locations and description and file T2 contains photographs and field observations for sample localities. File T3 contains portable x-ray fluorescence (XRF) data from powdered Troodos ophiolite samples. Files T4 - T8 contain sulphide trace element data from laser-ablation inductively-coupled-plasma mass-spectrometry (LA-ICP-MS) analysis of samples from various deposits in the Troodos ophiotlite. Files T9 and T10 contain bulk sample geochemistry from aqua regia digest and ICP-MS for deposits from the Troodos ophiolite. File T11 contains results from conventional ä34S analysis of sulfide minerals from Troodos deposits and file T12 contains x-ray diffraction analysis data from silica-rich deposits in the Troodos ophiolite. Data is used in papers available at https://doi.org/10.1016/j.oregeorev.2019.01.024, https://doi.org/10.1180/mgm.2018.81 and https://doi.org/10.1016/j.chemgeo.2019.119325 and in Dr Andrew Martin's PhD thesis, available at http://orca.cf.ac.uk/124346/.
Conventional power generation in the UK faces a significant challenge in the face of decarbonising and maintaining a reliable, secure and cost effective electricity supply. The requirement for fossil-fuel based systems to integrate smoothly with CCS technologies has led to the realistic consideration of oxyfuel based generating plant for CCGT-CCS processes. For CCS to become more technically and economically feasible, it has been suggested that the CO2 scrubbing component of the CCS process will work more effectively if the CO2 concentrations in the exhaust gas were higher. Hence, enhancement of oxygen in the combustion process and the enhancement of CO2 concentration in the plant exhaust via Exhaust Gas Recycling (EGR) can dramatically increase the net efficiency of CO2 scrubbers. Whilst oxyfuel and EGR are known to be potentially very promising technologies for integration with CCGT-CCS processes, there exists a significant lack of fundamental data on the design and reliable operation of industrial burner systems with this technology.

Sediment % coarse fraction (>63 microns), and abundance of fish teeth in coarse fraction. 2016 has been a record breaking year in terms of global temperatures. The high temperatures have resulted from a combination of elevated atmospheric pCO2 coupled with the global impacts of a strong El Nino event. There are many important components of the climate system, and the El Nino phenomenon demonstrates the importance of the low latitude Pacific Ocean. The warm pool of water in the western Pacific Ocean has not always had the same characteristics as it has today, and it has been proposed that its evolution over the past 15 million years has had a major impact on global climate. In order to understand how the warm pool might respond to future climate change, it is important to understand the drivers behind its past evolution. Did it respond simply to the changing shape of ocean basins through time? Or did it respond to other components of the climate system, such as sea level or latitudinal temperature gradients? The changes in warm pool structure may also have impacted the biological ecosystems, and hence the cycling of carbon in this region. The carbon cycle is another key component of the Earth's climate system. Understanding the causes and consequences of these long-term changes in the Pacific warm pool requires a two-pronged approach, using modelling in conjunction with proxy records for different parts of the climate system. This proposal aims to generate some key records of past high latitude temperature and ice volume that can be directly compared with changes in the warm pool through time. These records will be derived from geochemical analyses of microscopic marine fossils collected by the International Ocean Discovery Program (IODP).
Atmospheric Burner Tests With Oxygen, Nitrogen And Carbon Dioxide. Excel File. Testing undertaken May / June 2014. Data used is detailed in report: Oxyfuel And Exhaust Gas Recirculation Processes In Gas Turbine Combustion For Improved Carbon Capture Performance. August 2014. Grant number: UKCCSRC-C1-26.
This dataset contains data from two publications investigating mackinawite FeS in an aqueous environment. The first includes the derivation and validation of the force field parameters necessary to model the system (http://link.springer.com/article/10.1007/s00214-015-1782-8). In the second publication, the force field is employed to predict the structural and dynamical properties of water at the interface with the (001) surface of mackinawite (http://scitation.aip.org/content/aip/journal/jcp/144/9/10.1063/1.4942755).
Pulleniatina sample weights U1486. Grant abstract: This grant supports the participation of UK scientists Professor Paul Pearson in Expedition 363 of the International Ocean Discovery Program which plans to study the history of the 'Indo-Pacific Warm Pool' over the last 15 million years. It includes costs to cover his time while on board ship (2 months at sea) and post-expedition scientific study. Sea surface temperatures exceed 28oC across a huge area of the tropical western Pacific and Indian Oceans. Known as the Indo-Pacific Warm Pool (IPWP), this area is fundamental to the global atmospheric circulation and hydrologic cycle. The IPWP is intensifying with global warming, but modelling its likely future is challenging. Expedition n363 aims to study its temperature and climatic history over the past 15 million years, including through glacial to interglacial climate cycles and back to the globally warm Miocene epoch. Understanding its past history will help determine if its current temperature is near to its likely maximum or if global warming can cause much greater intensification in the future. Professor Pearson is a specialist in the study of microscopic fossils called planktonic foraminifera. He will study the evolution of the ocean plankton in the region over the study period, in relation to climatic change and sea level fluctuations which greatly affect the distribution of land masses and shallow seas and hence ocean current patterns. The foraminifera are also used to determine the age of the sediments drilled (called biostratigraphy) and providing other expedition scientists with a high quality planktonic foraminifer biostratigraphy will be one of the main features of this project. In additional there is a particular focus on an evolutionary lineage of foraminifera called Pulleniatina which has considerable untapped potential for stratigraphic work and also as a case study in the detailed speciation and extinction of a group of plankton. Study of this group will be facilitated by the large populations and varying morphology exhibited by them and because, like snails, they can be left or right handed and the pattern of coiling through time and across space is highly complex and potentially very informative.
