Heterogeneity and evolution of the Miocene Iceland mantle plume
(The University of Edinburgh, 2020-11-30)The North Atlantic Igneous Province (NAIP) is unique in that it presents a complete magmatic history from ~62 Ma to today. This provides an unrivalled opportunity to study the geochemical and thermal evolution of a mantle ... -
Post-orogenic topography and sediment flux of mountain-foreland basin systems: Miocene erosion and sediment yield from the Pyrenees
(The University of Edinburgh, 2021-07-31)Considerable research has been focused on the syn-orogenic evolution of mountain belts in order to explore interactions between tectonic, climate and surface processes. Comparatively, limited work has been carried on the ... -
Catchment subsurface water storage, mixing and flowpaths: implications for land cover change as a natural flood management strategy
(The University of Edinburgh, 2020-11-30)Efforts are increasing globally to harness the potential of forests to alter catchment water runoff and storage dynamics as a ‘natural flood management’ (NFM) strategy, particularly given a projected rise in the frequency ... -
Disentangling composite forcings on river channel steepness in heterogeneous landscapes
(The University of Edinburgh, 2020-11-30)Early geomorphological studies quickly realised the close relationship between the geometrical characteristics of river networks with the geological, tectonic and climatic context of the regions the river crosses - the ... -
Nitrous oxide emissions from grazed grasslands: novel approaches to assessing spatial heterogeneity
(The University of Edinburgh, 2020-11-30)Nitrous oxide (N2O) is a potent greenhouse gas mainly produced by microbial processes in the soil. Anthropogenic N2O is principally emitted from soils after nitrogen fertiliser and manure applications on agricultural land. ... -
Oilseed rape and pollinators: the impact of variety on resource availability and pollination resilience
(The University of Edinburgh, 2020-11-30)Mass-flowering crops help support the nutritional demands of insect pollinators in agricultural environments. With an estimated 70% of crops experiencing increased yields through animal pollination, recent declines in ... -
Understanding changes to food environments and diet through trade liberalisation: a study at three scales
(The University of Edinburgh, 2020-11-30)Although obesity has been commonly considered an individual problem (including unhealthy behaviours and genetic component), the steep rise of overweight and obesity prevalence in the last three decades holds a strong ... -
Nitrogen fluxes in forests from atmospheric deposition to soil: use of water flux monitoring and stable isotopes to close gaps in nitrogen transfers
(The University of Edinburgh, 2021-07-31)Temperate forest ecosystems are significant sinks for atmospheric nitrogen (N) deposition (Ndep) yielding benefits such as protection of waterbodies from eutrophication and enhanced sequestration of atmospheric CO2. ... -
Mechanisms of climate variation in the broader Mexican-United States region: the role of atmospheric circulation and anthropogenic forcing
(The University of Edinburgh, 2021-07-31)The climate of the region comprising Central America, Mexico and the United States (US) has undergone important temperature and precipitation changes in the recent decades. For instance, a rapid warming has been identified, ... -
In pursuit of just forest governance: lessons from the everyday practices of environmental impact assessment in Indonesia
(The University of Edinburgh, 2021-07-31)This thesis explores the role of “intermediary actors” in the inclusion (or exclusion) of environmental justice concerns (distributive, procedural and recognitional justice) within the Indonesia’s Environmental Impact ... -
Earthquake nucleation: small signals from Big Data
(The University of Edinburgh, 2020-11-30)Catastrophic failure events, such as earthquakes, volcanic eruptions and landslides, are linked by material failure processes. Seismicity and strain data can be used to track the failure processes that might be occurring ... -
Impact of intra-layer velocity and density variations on seismic characterization of a thin layer
(The University of Edinburgh, 2020-11-30)Seismic exploration has progressed greatly in the past 75 years due to advances in seismic acquisition and processing. One interpretation technique used by geoscientists is measuring amplitude-variations-with-offset (AVO). ... -
Evaluating competition, interactions and trait differences between vulnerable marine ecosystem taxa in climate changing ocean: laboratory studies on flow and feeding responses by gorgonians (Condor seamount) and cold-water scleractinian corals, sponges and bivalves (Norwegian shelf).
(The University of Edinburgh, 2021-07-31)Cold-water corals reefs, gardens and sponge grounds are vulnerable marine ecosystems (VMEs) as defined by UN resolution 61/105. These VMEs are protected from destructive fishing practices and are recognised due to the ... -

Identifying river geodiversity in Lower Mekong tributaries using supervised classification of Sentinel-2 imagery
(The University of Edinburgh, 2021-11-01)This project aims to improve the environmental data available for river basin managers when deciding Freshwater Protected Area (FPA) location. Due to the absence of information on critical habitat location and difficulty ... -
Time evolution of the electric field by the rapid expansion method in controlled-source electromagnetic (CSEM) applications
(The University of Edinburgh, 2021-07-31)I address the problem of modelling the low-frequency, time-domain controlled-source electromagnetic (CSEM) data by the rapid expansion method (REM). The CSEM method is an active EM exploration method that is recognized as ... -
Fragile dreams: exploring narratives of support, widowhood & caring in later life migration
(The University of Edinburgh, 2021-07-31)My ethnographic work in the Costa del Sol region of Spain explores the complex social relationships that constitute and shape the daily lives of older British migrants. Through individual narratives and ethnographic ... -
Mafic rock perspective on the magmatic maturation of a large scale silicic system: a multidisciplinary study of basalt in the Taupo Volcanic Zone, New Zealand
(The University of Edinburgh, 2021-07-31)Large-scale silicic systems are characterised by eruption of rhyolite composition magma in caldera-forming events. This often produces pyroclastic flows, which can travel >100km from the vent. A key question in volcanology ... -
Quetrupillán volcanic complex, Chile: Holocene volcanism, magmatic plumbing system, and future hazards
(The University of Edinburgh, 2021-07-31)The Quetrupillán Volcanic Complex in the Southern Andes of Chile (39°30’ S, 71°43’ W) is a composite volcanic system that has been active since the Pleistocene (>15 ky). It consists of a truncated and eroded stratocone ... -
Chronometers and chronometry on British Voyages of Exploration, 1819-1836
(The University of Edinburgh, 2021-07-31)This thesis demonstrates how a historical geography of the chronometer can inform our understanding of the production and circulation of scientific knowledge at sea. The history and development of the marine chronometer ...
