Rapid atmospheric warming, especially at high altitude, leads to alpine mountain landscapes becoming more vulnerable to mass movements and consequently unstable. For example, decay of mountain permafrost contributes to rockfalls, landslides and debris flows; glaciers are retreating and losing mass at alarming rates, exposing unstable slopes that are more likely to fail; and meltwater, which collects in a growing number of glacial lakes, can pose an outburst flood hazard, putting communities and infrastructure downstream at risk of damage. Occurring now with increasing frequency, these natural phenomena often combine to create complex multi-hazard cascades that are more powerful and have a …
Migration Kinetics Of Cadmium And Lead From Ceramic Mugs, Andrew Turner
Migration Kinetics Of Cadmium And Lead From Ceramic Mugs, Andrew Turner
School of Geography, Earth and Environmental Sciences
Cadmium and Pb are heavy metals of high concern owing to their impacts on human health. In this study, the migration of Cd and Pb from both the interior and exterior (lip area) surfaces of new and second-hand ceramic mugs has been measured as a function of time over a 24-h period using 4 % acetic acid. Via regression analysis, data were fitted with a diffusion equation, yielding reaction rate constants and 24-h migratable concentrations. Migration was more significant from the external surfaces for both metals, and especially where the rim area was overglazed with decorative Cd sulphoselenide pigments. Here, …

Introduction To The Special Section On Earthquakes In Slowly Deforming Mountain Belts And The High Atlas Earthquake Of 8 September 2023, Fida Medina, Youssef Timoulali, Mustapha Meghraoui, Sarah Boulton, Eric Fielding
School of Geography, Earth and Environmental Sciences
Earthquakes in slowly deforming mountain belts result from low‐tectonic loading and occur on individual fault segments. Although most of the significant seismic strain rate concentrates along the plate boundaries, large earthquakes with may still be generated along faults in regions at a distance (≫100 km) from plate boundaries. Intraplate regions, or continental interiors, exhibit active deformation characterized by relatively low tectonic and seismic strain rates (<5 mm/yr; Johnston, 1996), consistent with geodetic strain rates and models of plate motions that predict comparable velocities (Kreemer et al., 2014). Active faults in continental interiors...
Small Scale Analysis Of Urban Air Quality And Public Health In London, Uk, Provides Insights For Targeted Interventions, Alan Smith, Tim Daley
Small Scale Analysis Of Urban Air Quality And Public Health In London, Uk, Provides Insights For Targeted Interventions, Alan Smith, Tim Daley
School of Geography, Earth and Environmental Sciences
Understanding the impact of scale and zonation is critical for accurately assessing population health in relation to air quality and demographic data. Using existing census geographies, we analyse spatial clustering and statistical associations across different census scales, focussing on vulnerable sociodemographic groups and temporal exposure patterns. This study aims to assess how different spatial resolutions affect the strength and interpretation of associations between air pollution, sociodemographic variables, and self-reported health. It also evaluates whether finer-scale, health-need-based zoning provides a more accurate basis for public health analysis. Exposure to higher PM2.5 concentrations, and having an undrlying disability, or long-term illness shows …
A Potential New Sea Surface Temperature Proxy Based On Isomeric Highly Branched Isoprenoid Lipid Biomarkers: Ez25, Simon T. Belt, Lukas Smik, Katrine Husum, Jochen Knies
A Potential New Sea Surface Temperature Proxy Based On Isomeric Highly Branched Isoprenoid Lipid Biomarkers: Ez25, Simon T. Belt, Lukas Smik, Katrine Husum, Jochen Knies
School of Geography, Earth and Environmental Sciences
Two tri-unsaturated and isomeric (E/Z) highly branched isoprenoid (HBI) diatom lipid biomarkers were quantified in 228 water column samples collected from the English Channel, West Svalbard (Arctic), the Scotia Sea (Southern Ocean) and East Antarctica. We found that the relative amounts of the two HBIs correlate well with water temperatures taken at the time of sampling. Based on these findings and some other HBI data reported previously, we suggest that the proportion of the HBI E-isomer (termed EZ25) may serve as a new proxy for palaeo sea surface temperatures, including in the polar regions. Next steps will involve determination of …

Microplastics And Other Plastic-Like Microdebris In Sediments From The Dart River And Estuary, Southwest England, Maia Killian, Andrew Turner
School of Geography, Earth and Environmental Sciences
Surficial sediment samples (n = 10) collected from a transect of a river-estuary (Dart) in southwest England have been analysed for geochemical characteristics, anthropogenic metals (Cr, Cu, Sn, Pb, Zn), and microplastics (∼50 μm–5 mm) and other microplastic-like debris. Results indicated the finest grains towards the lower river and upper estuary, a seaward increase in sedimentary Ca, and loss on ignition ranging from about 0.7 to 4 %. Anthropogenic metals were heterogeneously distributed throughout the catchment with maximum concentrations in the river or lower estuary. Microplastics were dominated by fibres, with concentrations ranging from 110 to 1800 kg−1 and composition …
Big Ugly Lumps? (Counter)Terrorism And The Everyday Atmospheres Of Hostile Vehicle Mitigation, Carrie Benjamin, Sam Berlin, Sara Fregonese, Paul Simpson
Big Ugly Lumps? (Counter)Terrorism And The Everyday Atmospheres Of Hostile Vehicle Mitigation, Carrie Benjamin, Sam Berlin, Sara Fregonese, Paul Simpson
School of Geography, Earth and Environmental Sciences
Adopting an atmospheric lens on the everyday and open-ended crisis of contemporary terror threats in cities in Western Europe, this article unpicks the contemporary logics, desires, and effects of the State in matters of urban counterterrorism by exploring the felt qualities and dispositions of the public around Hostile Vehicle Mitigation (HVM) measures in Birmingham (UK). It argues that the atmospheres around counterterrorism that security officials and business representatives aim to produce, which seeks to reassure the public rather than cause alarm, has led to ambivalent acceptance of HVM by city centre users. The paper shifts away from discursive and socio-technical …

Subseafloor in situ temperatures in a drilled hole in the Anhydros Basin, Aegean Sea, measured during International Ocean Discovery Program (IODP) Expedition 398, yielded a low heat flow (<0.023 W/m2) despite active magmatism and rifting in the region. The coldest and highest temperatures were 13.9°C at 52.5 m below seafloor (mbsf) and 15.5°C for the deepest measurement at 360.4 mbsf, respectively. Comparison of a heat transfer model with measurements suggests that sea bottom temperatures during the last glacial period were up to 10°C cooler than Holocene temperatures. The magnitude of Holocene warming co-varies with the geothermal heat flow: if …

2.5% of global carbon emissions result from air travel, underscoring the need for sustainable aviation fuels (SAF) derived from second-generation lignocellulosic biomass to enhance the green credentials of the aviation sector. This study demonstrates the first solvent-free photocatalytic conversion of furfural (FAL) and cyclopentanone (CPO) to produce 2,5-bis(2-furylmethylidene)cyclopentanone (F2Cp), a jet fuel precursor, using Ti-SBA-15 catalysts, synthesized via alkoxide grafting and controlled titanium surface coverage. Sub-monolayer titania films on SBA-15 supports are achieved with tuneable Ti content, confirmed by XPS (X-ray photoelectron spectroscopy), UPS (ultraviolet photoelectron spectroscopy), REELS (reflectance electron energy loss spectroscopy), ISS (ion scattering spectroscopy), and Raman analysis. …

Biomass-derived diols are key chemical building blocks for the sustainable chemical manufacturing of textiles and plastics, however their synthesis by a selective, scalable process from holocellulose is challenging. Furfuryl alcohol (FALC) is a potential precursor to 1,5-pentanediol (1,5-PeD) through acid-catalysed hydrogenolysis, and hence the impact of oxide support acidity on this reaction over Pt nanoparticles was investigated under batch and continuous flow in toluene. Platinum dispersed over weakly acidic fumed silica and mesoporous SBA-15 supports was almost inactive towards furfuryl alcohol at 150 °C and 10 bar H2 and promoted decarbonylation and hydrodeoxygenation of FALC to furan and methyltetrahydrofuran, respectively. …

Alkylamines, volatile organic nitrogen compounds with low molecular weight, are present in the surface ocean and participate in the marine biogeochemical nitrogen cycle, atmospheric chemistry and cloud formation. Alkylamines have been detected in polar regions, suggesting that these areas constitute emission hotspots of these compounds. However, knowledge of the sea surface distribution patterns and factors modulating alkylamines remain limited due to their high reactivity and low concentrations, which hamper accurate measurements. We investigated the presence and distribution of alkylamines in seawaters around the Antarctic Peninsula and the northern Weddell Sea during the late austral summer and explored their potential links …

School of Geography, Earth and Environmental Sciences
The past occurrence of an extreme ~1-kilometer–thick Arctic Ocean–Nordic Seas ice shelf has been inferred from submarine landscape features and geochemical records, although fundamental aspects of its characteristics, impacts, and timing remain highly debated. Here, we challenge this pan-Arctic glaciation hypothesis by investigating two sites from the Arctic-Atlantic gateway (AAG) and the Nordic Seas. Suborbital to millennial-scale surface water bioproductivity changes provide no evidence for a continuous ice shelf in the AAG and the Nordic Seas over the past ~750,000 years. Instead, proxy data and model simulations reveal the persistent presence of seasonal sea ice cover and open water phytoplankton …

The Theoretical Role Of The Wind In Aerosolising Microplastics And Nanoplastics From Coastal Combined Sewer Overflows, Lauren Biermann, David Moffat, Clive E Sabel, Thomas E Stovin
School of Geography, Earth and Environmental Sciences
Inhaled microplastics and nanoplastics (MNPs) have shown bio-persistence in the body, with concerning implications for human health. Airborne MNPs primarily originate from terrestrial sources, but sea air may contribute when onshore 'aerosolising' winds coincide with high concentrations of MNPs in surface waters. From the thousands of cities worldwide with Combined Sewer Overflows, millions to billions of MNPs can be discharged daily into rivers, estuaries, and the sea. To assess the possible links between water pollution and air quality, we analysed two years of Combined Sewer Overflows (spills) off Plymouth, UK, alongside same-day and long-term meteorological and satellite data. Winds exceeding …

School of Geography, Earth and Environmental Sciences
Offshore produced water (PW) is one of the largest and most chemically complex effluents of waste directly and intentionally discharged into the marine environment. Although it is well known that PW can be severely toxic to marine organisms, the mechanisms of toxicity remain poorly understood, contributed by the lack of comprehensive chemical characterization of the PW. In this study, we applied elements of effects-directed analysis with the aim to identify organic chemical drivers of toxicity in PW towards fish early life stages. A solvent extract of a PW was fractioned based on compound functionality and chemically characterized by a concert …

The Ross Ice Shelf, Antarctica’s largest by area, may face increased instability under future warming, threatening the Antarctic Ice Sheet. Understanding its past response to climate change is critical for anticipating future sea-level rise. We present a multi-proxy reconstruction of ocean and cryosphere conditions in the Ross Sea over the past 40,000 years. Our data show that warm Circumpolar Deep Water reached the JOIDES Trough in the western Ross Sea shortly after the Last Glacial Maximum, coinciding with the retreat of an ancestral ice shelf. This oceanic warming aligns with a southward shift of both the westerly and easterly wind …

Characteristics, Behaviour And Fluxes Of Microplastics In The Coastal Boundary Zones Of The Persian Gulf And Oman Sea, Sajjad Abbasi, Andrew Turner
School of Geography, Earth and Environmental Sciences
Relatively little is known about microplastics (MPs) in the atmosphere of the coastal zone, including their interaction with the sea surface. In this study, MPs have been determined and characterised in the lower atmosphere, advecting air, depositing dusts, coastal sediments and seawater of the Persian Gulf and Oman Sea using a variety of sampling techniques (including filtration of water and pumped air and deployment of a vertical array of sediment traps). MPs were detected in all samples and were dominated by fibres that were, in most cases, small (<100 μm) and black. MP numbers captured in advecting air showed no trends with height or differences between locations or deployments over land and sea, but a clear increase was observed during strong winds. MPs in atmospheric suspension and in deposited dusts, sediments and seawater were also heterogeneously distributed. Environmental or transport pathway fractionation was evident according to morphology and particle size (% fibres and % small fibres) and to polymer density. Regarding the latter, relatively low-density polymers (e.g., polyethylene, polypropylene) were more abundant in the atmosphere, advecting air and seawater, whereas higher density polymers (e.g., regenerated cellulosics, polyethylene terephthalate) were more abundant in settling dusts and sediments. Fluxes, based on particle counts and converted MP m−2 h−1, revealed advection (up to ∼ 1.2 × …

The snow and glaciers of the Peruvian Andes provide vital water supplies in a region facing water scarcity and substantial glacier change. However, there remains a lack of understanding of snow processes and quantification of the contribution of melt to runoff. Here we apply a distributed glacio-hydrological model over the Rio Santa basin to disentangle the role of the cryosphere in the Andean water cycle. Only at the highest elevations (>5000 m a.s.l.) is the snow cover continuous; at lower elevations, the snowpack is thin and ephemeral, with rapid cycles of snowfall and melt. Due to the large catchment …

Seasonal vertical migration of large lipid-rich copepods is often described as a mass descent of animals when primary production ceases, with important implications for mesopelagic food webs and global carbon sequestration. This view ignores the existence of surface-resident individuals, but here we show that non-migrants can form a substantial part of the populations of polar migrant species. In the Central Arctic Ocean, the biomass-dominant Calanus hyperboreus was evenly distributed throughout the water column from November 2019 to March 2020, with ~20% of subadults and adult females remaining in the upper 200 m and ~41% migrating to 1000–2000 m. These vertical …

Because of the ubiquity of microplastics (MPs) in the environment there are concerns regarding human exposure. In this study, MPs have been determined in three physiological fluids: urine, sputum and bronchoalveolar fluid (BALF); from 30 adult patients in Iran with respiratory conditions. A total of nine small (20–100 μm) and mainly green and red fibres of polyethylene, polypropylene and polystyrene construction were detected in urine samples of eight participants. By contrast, 358 MPs that were dominated by small, white and transparent fibres, but also included larger (100–500 μm) fibres and fragments and spherules of various sizes, were detected in sputum …
The Density Of Virgin, Consumer And Environmental Plastics: An Investigation Using Gas Displacement Pycnometry, Andrew Turner, Katie Jones, Montserrat Filella
The Density Of Virgin, Consumer And Environmental Plastics: An Investigation Using Gas Displacement Pycnometry, Andrew Turner, Katie Jones, Montserrat Filella
School of Geography, Earth and Environmental Sciences
Density is a fundamental property of plastics and is particularly significant in determining the transport and fate of waste plastics that enter aquatic systems. However, densities are rarely determined in the environmental literature and values employed for modelling or impacts are often unsourced or derived from secondary databases. In this study, we employ helium displacement pycnometry to determine the skeletal densities of non-porous plastics whose polymer composition had been established from manufacturer's data, resin codes or Fourier transform infrared spectrometry. Two independent, collaborative laboratories, providing measurements within 3.5 % of each other and with precisions of <1 % (as relative standard deviation), analysed a total of 42 virgin, consumer and environmental plastics consisting of ten common polymer types. Measured densities of plastics in all categories, and most notably for polybutylene terephthalate, polyethylene terephthalate, polypropylene and polyvinyl chloride, were often outside the ranges reported by a comprehensive online resource. Possible reasons for discrepancies include the occurrence of dense additives (evaluated by X-ray fluorescence analysis), the presence of inaccessible microscopic pores below a laminated surface, contamination of the main polymer by a secondary one, and structural changes on weathering. Regardless of precise causes, most results suggest that individual polymers have a broader range of densities than is generally published or considered in the literature. Accordingly, and in particular where buoyancy is critical, more precise, sample-specific measurements are recommended.

International Ocean Discovery Program (IODP) Expedition 399 collected new cores from the Atlantis Massif (30°N; Mid-Atlantic Ridge), an oceanic core complex that hosts the Lost City hydrothermal field (LCHF). Studies of the Atlantis Massif and the LCHF have transformed our understanding of tectonic, magmatic, hydrothermal, and microbial processes at slow-spreading ridges. The Atlantis Massif was the site of four previous expeditions (Integrated Ocean Drilling Program Expeditions 304, 305, and 340T and IODP Expedition 357) and numerous dredging and submersible expeditions. The deepest IODP hole in young (<2 My) oceanic lithosphere, Hole U1309D, was drilled ~5 km north of the LCHF and reached 1415 meters below seafloor (mbsf) through a series of primitive gabbroic rocks. A series of 17 shallow (<16.4 mbsf) holes were also drilled at 9 sites across the south wall of the massif during Expedition 357, recovering heterogeneous rock types including hydrothermally altered peridotites, gabbroic, and basaltic rocks. The hydrologic regime differs between the two locations, with a low-permeability conductive regime in Hole U1309D and a high- (and possibly deep-reaching) permeability regime along the southern wall.

The February 6, 2023 Kahramanmaraş earthquake doublet resulted in a range of devasting impacts on the built and natural environments. Here the macroseimic intensity of the event is assessed using the Environmental Seismic Intensity Scale (ESI 2007), which considers a range of primary and secondary earthquake environmental effects (EEEs) resulting from the causative earthquakes. These features were documented as part of the hybrid Earthquake Engineering Field Investigation Team (EEFIT) mission and by numerous other studies in the aftermath of the earthquakes. The primary fault ruptures along segments of the East Anatolian Fault Zone exceeded 350 km along the Pazarcık segment …

Encountering Coasts: The Contested Geographies Of Young People's Coastal Citizenship[S], Mark Holton
School of Geography, Earth and Environmental Sciences
This paper examines the contested geographies of young people's citizenship practices and performances in marine and coastal environments. This is important in developing original knowledge of how encounters with new and different coastal places, practices, people, morals and ethics can affect young people's citizenship practices and performances and how young people relate meaningfully with[in] coastal environments. Using a novel digital scrapbooking technique and qualitative interviews, conducted with 22 young adults aged 18–30 in Plymouth, UK, this paper examines how and why young people's everyday engagements and encounters with coastal environments can shape their understandings of environmental and social care. In …

The European Union's goal of achieving climate neutrality by 2050, outlined in the European Green Deal, is supported by numerous studies providing insights into pathways and emission reduction strategies in the energy sectors. However, model comparisons of such pathways are less common due to the complex nature of climate and energy modelling. Our study brings together integrated assessment models and energy system models under a common framework to develop EU policy scenarios: a Current Trends scenario reflecting existing policies and trends and a Climate Neutrality scenario aligned with the EU's emission reduction target. Both scenarios project reduced final energy consumption …
