The effect of cooling rate on immiscible silicate liquid microstructure: An example from the Palaeogene dykes of Northeast England
(2019)The migration and accumulation of immiscible silicate liquids may play a significant role in the differentiation of crustal magma bodies and the formation of some economic mineral deposits. However, our understanding of ... -
Neoproterozoic crystalline exotic clasts in the Polish Outer Carpathian flysch: remnants of the Proto-Carpathian continent?
(2019)Crystalline exotic boulders within the sedimentary sequences of the Outer Carpathians likely represent Proto-Carpathian basement, which was exposed and eroded during the Mesozoic and Cenozoic evolution of the Western ... -
Spatial and temporal trends in exhumation of the Eastern Himalaya and syntaxis as determined from a multitechnique detrital thermochronological study of the Bengal Fan
(2019)The Bengal Fan provides a Neogene record of Eastern and Central Himalaya exhumation. We provide the first detrital thermochronological study (apatite and rutile U-Pb, mica Ar-Ar, zircon fission track) of sediment samples ... -
Regional-scale structure and dynamics of the crust, upper mantle and transition zone from waveform tomography with massive datasets
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2020)In the last decade, the number of seismic stations deployed globally increased dramatically, allowing to construct tomographic models with increasing resolution. Seismic data coverage however, is not homogeneous across the ... -
Understanding the Lived Experiences of Gender Minority Students in Irish Third-Level Education: Steps Towards Achieving Safety and Inclusion
(National LGBTQI Federation (NXF), 2020)This policy brief provides an overview of the findings in “Understanding the Lived Experiences of Gender Minority Students in Irish Third-Level Education: A National Survey of Transgender, Non-Binary, and Gender Non-Conforming ... -
A comparison of sampling methods for seawater microplastics and a first report of the microplastic litter in coastal waters of Ascension and Falkland Islands
(2018)To date there is no gold standard for sampling microplastics. Zooplankton sampling methods, such as plankton and Neuston nets, are commonly used to estimate the concentrations of microplastics in seawater, but their ability ... -
Importance of reporting ancillary site characteristics, and management and disturbance information at ICOS stations.
(2018)There are many factors that influence ecosystem scale carbon, nitrogen and greenhouse gas dynamics, including the inherent heterogeneity of soils and vegetation, anthropogenic management interventions, and biotic and abiotic ... -
Development of a Climate Forcing Observation System for Africa: Data-Related Considerations
(2019)In the case of the African continent, the estimates of most climate forcing components are associated with large uncertainties, above all the greenhouse gas budget. The EU-funded SEACRIFOG project is designing an observation ... -
Do Results based management frameworks frustrate or facilitate effective development practice? Experiences of the Irish International Development Sector
(2019)Utilising a case study methodological approach to analyse the Irish practitioner experience, this article examines if the introduction of results-based frameworks (RBFs) have led to greater impact and accountability to ... -
The marine isotope stage 1 to 5 cryptotephra record of Tenaghi Philippon, Greece: Towards a detailed tephrostratigraphic framework for the Eastern Mediterranean region
(2018)The iconic climate archive of Tenaghi Philippon (TP), NE Greece, allows the study of short-term palaeoclimatic and environmental change throughout the past 1.3 Ma. To provide high-quality age control for detailed palaeoclimate ... -
The ecology and evolution of endemic shrimp in Lake Tanganyika
(Trinity College Dublin. School of Natural Sciences. Discipline of Zoology, 2019)An exceptionally diverse group of shrimp species in the genera Atyella, Caridella, Limnocaridina and Macrobrachium is found in Lake Tanganyika, Africa, while the region is otherwise relatively poor in shrimp species. In ... -
Combined zinc-lead isotope and trace-metal assessment of recent atmospheric pollution sources recorded in Irish peatlands
(2019)Atmospherically-fed Earth surface archives such as ombrotrophic peatlands, lake sediments, and ice consistently show an upward increase in Zn concentrations of hitherto unclear origin. Here, we present a combined stable ... -
Co-existing fluid and silicate inclusions in mantle diamond
(2006)We document the compositions of co-existing silicate macro-inclusions and fluid micro-inclusions in the fibrous coats of eight coated diamonds from the Panda kimberlite (Canada). The mineral inclusions in the diamond coats ... -
Quartz-bearing C-O-H fluid inclusions diamond: Retracing the pressure-temperature path in the mantle using calibrated high temperature IR spectroscopy
(2007)Infrared spectra of C–O–H micro-inclusions were collected from a micro-inclusion bearing diamond during step-heating and freezing experiments to examine fluid speciation as a function of pressure and temperature. The ... -
Does Large Igneous Province Volcanism Always Perturb the Mercury Cycle? Comparing the Records of Oceanic Anoxic Event 2 and the End-cretaceous to Other Mesozoic Events
(2018)Mercury (Hg) is increasingly being used as a sedimentary tracer of Large Igneous Province (LIP) volcanism, and supports hypotheses of a coincidence between the formation of several LIPs and episodes of mass extinction and ... -
Broadband Surface Wave Tomography of Ireland, Britain and Other Regions
(Trinity College Dublin. School of Natural Sciences. Discipline of Geology, 2019)Over the last decades, seismic surface-wave studies have produced increasingly detailed images of the Earth s structure at a regional scale. In this study, we have tuned well-established techniques and when required ... -
Localization of YAP activity in developing skeletal rudiments is responsive to mechanical stimulation
(University of Edinburgh (datashare), 2020)Background: Normal skeletal development, in particular ossification, joint formation and shape features of condyles, depends on appropriate mechanical input from embryonic movement but it is unknown how such physical stimuli ... -
Trace element and Pb isotope fingerprinting of atmospheric pollution sources: A case study from the east coast of Ireland
(2018)Unravelling inputs of multiple air pollution sources and reconstructing their historic contribution can be a difficult task. Here, new trace metal concentrations and Pb isotope data were combined for a radionuclide ... -
An exsolution origin for Archean mantle garnet
(2017)It is well established that the cratonic subcontinental lithospheric mantle (C-SCLM) represents a residue of extensively melted peridotite. The widespread occurrence of garnet in C-SCLM remains a paradox because experiments ...
