Sustainable Geoscience, I Stewart
School of Geography, Earth and Environmental Sciences
To the editor – Humankind is using more natural resources than ever before. The way we are using these materials has already started to affect our ecosystem irreversibly. Overuse of the Earth’s natural wealth has the potential to impact our ability to sustain the economy, protect national security and preserve the natural environment. Geoscientists are well placed to make critical contributions to contemporary sustainability issues. Yet, most geologists have little or no direct involvement in the growing societal shift towards sustainable development. Humans are now a dominant geological force on the planet. The cumulative impacts of anthropogenic changes are sufficiently …

Extreme Wave Activity During 2013/2014 Winter And Morphological Impacts Along The Atlantic Coast Of Europe, Gerd Masselink, Bruno Castelle, Tim Scott, Guillaume Dodet, Serge Suanez, Derek Jackson, France Floc'h
School of Biological and Marine Sciences
AbstractStudies of coastal vulnerability due to climate change tend to focus on the consequences of sea level rise, rather than the complex coastal responses resulting from changes to the extreme wave climate. Here we investigate the 2013/2014 winter wave conditions that severely impacted the Atlantic coast of Europe and demonstrate that this winter was the most energetic along most of the Atlantic coast of Europe since at least 1948. Along exposed open‐coast sites, extensive beach and dune erosion occurred due to offshore sediment transport. More sheltered sites experienced less erosion and one of the sites even experienced accretion due to …

Shaping The Role Of 'Fast' And 'Slow' Drivers Of Change In Forest-Shrubland Socio-Ecological Systems, Agostino Ferrara, Claire Kelly, Geoff A. Wilson, Angelo Nolè, Giuseppe Mancino, Sofia Bajocco, Luca Salvati
School of Geography, Earth and Environmental Sciences
The temporal speeds and spatial scales at which ecosystem processes operate are often at odds with the scale and speed at which natural resources such as soil, water and vegetation are managed those. Scale mismatches often occur as a result of the time-lag between policy development, implementation and observable changes in natural capital in particular. In this study, we analyse some of the transformations that can occur in complex forest-shrubland socio-ecological systems undergoing biophysical and socioeconomic change. We use a Multiway Factor Analysis (MFA) applied to a representative set of variables to assess changes in components of natural, economic and …

Lead In Exterior Paints From The Urban And Suburban Environs Of Plymouth, South West England, Andrew Turner, Kevin R. Solman
School of Geography, Earth and Environmental Sciences
The dry weight concentrations of lead in paints on a variety of structures in the urban and suburban environs of a British city (Plymouth, south west England) have been determined in situ and ex situ by field-portable x-ray fluorescence spectrometry. Lead was detected in 221 out of 272 analyses, with overall median and mean concentrations of 4180 g g-1 and 29,300 g g-1, respectively, and a maximum concentration of 390,000 g g-1. The highest concentrations were observed in extant paints on poorly maintained, metallic structures, including railings, gates, telephone kiosks and bridges, in various yellow road line paints, and in …
Understanding The Planning Challenges Of Brownfield Development In Coastal Urban Areas Of England, Craig Leger, Christopher Balch, Stephen Essex
Understanding The Planning Challenges Of Brownfield Development In Coastal Urban Areas Of England, Craig Leger, Christopher Balch, Stephen Essex
School of Geography, Earth and Environmental Sciences
Coastal settlements, whether rooted in port, defence or tourism economies, have experienced considerable economic, social and environmental change over the last 30–40 years, which has often resulted in building obsolescence and vacant land. Brownfield sites, especially on the waterfront, are strategically valuable, but can be constrained by costs of treatment, the fragmentation of available plots, complex landownership and declining property values. This paper addresses the need for a better understanding of the characteristics of brownfield land in English coastal communities and the challenges faced by planning in the regeneration of these sites through an analysis of the National Land Use …

The Miocene – Pliocene Boundary And The Messinian Salinity Crisis In The Easternmost Mediterranean: Insights From The Hatay Graben (Southern Turkey)., Sarah J. Boulton, Christopher W. Smart, Chiara Consolaro, Avalon Snider
School of Geography, Earth and Environmental Sciences
The Hatay Graben is one of three easternmost basins in the Mediterranean that preserve sediments that span the Miocene-Pliocene boundary, including gypsums from the Messinian Salinity Crisis (MSC). Here we integrate existing data and present new sedimentological and micropalaeontological data to investigate the palaeoenvironments of late Miocene to early Pliocene deposits and place this important area into a regional stratigraphic framework. Six sections are described along a ~ W – E transect illustrating the key features of this time period. Late Miocene (Pre-MSC) sediments are characterised by open marine marls with a benthic foraminiferal fauna suggestive of water depths of …
Jointness In Farmers' Decision To Apply Pesticides In Multiple Crops And Its Determinants At The Farm Level In Bangladesh, S Rahman
School of Geography, Earth and Environmental Sciences
Decision about pesticide application for pest control is an issue of major concern, but research on factors affecting decision-making is limited. This study investigates jointness in farmers' decision to apply pesticides in multiple crops and socio-economic determinants of pesticide use across crops using a survey of 2083 farms from 17 districts in Bangladesh applying a multivariate Tobit model. Overall, 75.4% and 12.7% of the farmers applied pesticides in one and two crops, respectively. The decision to apply pesticides in multiple crops was found to be negatively correlated, providing evidence of jointness. Also, individual socio-economic factors exerted variable influences on pesticide …

AbstractBiologically active, fine‐grained sediment forms abundant sedimentary deposits on Earth's surface, and mixed mud‐sand dominates many coasts, deltas, and estuaries. Our predictions of sediment transport and bed roughness in these environments presently rely on empirically based bed form predictors that are based exclusively on biologically inactive cohesionless silt, sand, and gravel. This approach underpins many paleoenvironmental reconstructions of sedimentary successions, which rely on analysis of cross‐stratification and bounding surfaces produced by migrating bed forms. Here we present controlled laboratory experiments that identify and quantify the influence of physical and biological cohesion on equilibrium bed form morphology. The results show the …

An Evaluation Of Extraction Techniques For Arsenic In Staple Diets (Fish And Rice) Utilising Both Classical And Enzymatic Extraction Methods, Bashdar A. Sadee, Mike E. Foulkes, Steve J. Hill
An Evaluation Of Extraction Techniques For Arsenic In Staple Diets (Fish And Rice) Utilising Both Classical And Enzymatic Extraction Methods, Bashdar A. Sadee, Mike E. Foulkes, Steve J. Hill
School of Geography, Earth and Environmental Sciences
Enzymatic extraction methods were evaluated with classical extraction approaches for the determination of arsenic in food. The extraction efficiency for total arsenic was determined by analysing CRM materials DORM-3 fish protein, NIES 106 rice flour and GBW10015 spinach. These were compared with total arsenic concentration determined using microwave-assisted acid digestion and ICP-MS. The total arsenic concentrations in the CRM materials were in good agreement with the certified values. Enzymatic hydrolysis using trypsin has been successfully employed to extract arsenic species in DORM-3 and fish samples. Whilst this method of hydrolysing the proteins worked well for the fish samples, an alternative …

Ecological communities that experience stable climate conditions have been speculated to preserve more specialized interspecific associations and have higher proportions of smaller ranged species (SRS). Thus, areas with disproportionally large numbers of SRS are expected to coincide geographically with a high degree of community-level ecological specialization, but this suggestion remains poorly supported with empirical evidence. Here, we analysed data for hummingbird resource specialization, range size, contemporary climate, and Late Quaternary climate stability for 46 hummingbird–plant mutualistic networks distributed across the Americas, representing 130 hummingbird species (ca 40% of all hummingbird species). We demonstrate a positive relationship between the proportion of …

Promoting The 3rs To Enhance The Oecd Fish Toxicity Testing Framework., Th Hutchinson, Jr Wheeler, A Gourmelon, N Burden
School of Geography, Earth and Environmental Sciences
Fish toxicity testing has been conducted since the 1860's in order to help define safe levels of chemical contaminants in lakes, rivers and coastal waters. The historical emphasis on acute lethality testing of chemicals has more recently focussed on long term sublethal effects of chemicals on fish and their prey species. Fish toxicity testing is now embedded in much environment legislation on chemical safety while it is recognized that animal use should be Replaced, Reduced and Refined (the 3Rs) where possible. The OECD Fish Toxicity Testing Framework provides a useful structure with which to address the needs of environmental safety …

A New Method For The Rapid Analysis Of 1h-Pyrrole-2,5-Diones (Maleimides) In Environmental Samples By Two-Dimensional Gas Chromatography Time-Of-Flight Mass Spectrometry (Gc×Gc-Tof-Ms), S Naeher, Sk Lengger, K Grice
A New Method For The Rapid Analysis Of 1h-Pyrrole-2,5-Diones (Maleimides) In Environmental Samples By Two-Dimensional Gas Chromatography Time-Of-Flight Mass Spectrometry (Gc×Gc-Tof-Ms), S Naeher, Sk Lengger, K Grice
School of Geography, Earth and Environmental Sciences
Maleimides (1H-Pyrrole-2,5-diones) are monopyrrolic pigment derivatives with specific alkyl side chains that can be directly linked to their tetrapyrrole precursors, most notably chlorophylls and bacteriochlorophylls. These compounds can be used as palaeoenvironmental indicators such as, for instance, algal productivity and redox conditions in ancient and modern aquatic systems. Here, we present a new method using two-dimensional gas chromatography time-of-flight mass spectrometry (GC×GC-ToF-MS), which enables the rapid analysis of maleimides in complex mixtures and different matrices (e.g. sediments and soils), therefore largely simplifying the previous intricate maleimide purification protocol. This method also reduces the potential for bias associated with partial losses …

Student Geographies And Homemaking: Personal Belonging(S) And Identities, Mark Holton, Mark Riley
School of Geography, Earth and Environmental Sciences
Studies of the ‘geographies of students’ have become increasingly prevalent across the social sciences and are particularly concerned with the predilection for young UK University undergraduates to be mobile in their institutional choice. A more recent focus within this work has been upon student identities, with attention given to how the spaces to which students move and in which they settle can have both positive and negative consequences for the evolution of the student identity, and how such identities are often framed within the context of social activities; learning environments; friendship networks; or other sociocultural factors. This paper contributes to …

School of Geography, Earth and Environmental Sciences
Pollution is a global issue at the frontier between ecology, environmental science, management, engineering and policy. Legislation requires experiments to determine how much contamination an ecosystem can absorb before there are structural or functional changes. Yet, existing methods cannot realistically simulate regimes of chemical disturbance and determine impacts to assemblages in ecosystems. This is because they lack ecologically relevant species and biotic interactions, are logistically difficult to set up and lack environmentally relevant regimes of chemical and abiotic disturbance that organisms experience in polluted areas. We solved these long-standing environmental, logistical, experimental and ecological problems by developing a programmable dosing …

Denitrification As A Source Of Nitric Oxide Emissions From Incubated Soil Cores From A Uk Grassland, N Loick, Er Dixon, D Abalos, A Vallejo, Gp Matthews, Kl Mcgeough, R Well, C Watson, Rj Laughlin, Lm Cardenas
School of Geography, Earth and Environmental Sciences
Agricultural soils are a major source of nitric oxide (NO) and nitrous oxide (N2O), which are produced and consumed by biotic and abiotic soil processes. The dominant sources of NO and N2O are microbial nitrification and denitrification. While N2O emissions have been attributed to both processes, depending on the environmental conditions such as substrate availability, pH and water filled pore space (WFPS), NO emissions are thought to predominantly derive from nitrification. Although attributing gaseous emissions to specific processes is still difficult, recent findings challenge the latter of those assumptions. Using the gas-flow-soil-core method, i.e soil cores incubated under a He/O2 …

The early Holocene cooling, which occurred around 8200 calendar years before present, was a prominent abrupt event around the north Atlantic region. Here, we investigate the timing, duration, magnitude and regional coherence of the event as expressed in carbonate oxygen-isotope records from three lakes on northwest Europe's Atlantic margin in western Ireland, namely Loch Avolla, Loch Gealáin and Lough Corrib. An abrupt negative oxygen-isotope excursion lasted about 200 years. Comparison of records from three sites suggests that the excursion was primarily the result of a reduction of the oxygen-isotope values of precipitation, which was likely caused by lowered air temperatures, …

Historic mine sites are a major source of contamination to terrestrial and river environments. To demonstrate the importance of determining the significance of point and diffuse metal contamination and the related bioavailability of the metals present from abandoned mines a case study has been carried out. The study provides a quantitative assessment of a historic mine site, Wheal Betsy, southwest England, and its contribution to non-compliance with Water Framework Directive (WFD) Environmental Quality Standards (EQS) for Cd, Cu, Pb and Zn. Surface water and sediment samples showed significant negative environmental impacts even taking account of the bioavailability of the metal …
