Big Ugly Lumps? (Counter)Terrorism And The Everyday Atmospheres Of Hostile Vehicle Mitigation, Carrie Benjamin, Sam Berlin, Sara Fregonese, Paul Simpson Jul 2025

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. …

School of Geography, Earth and Environmental Sciences

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 …

Seasonal Sea Ice Characterized The Glacial Arctic-Atlantic Gateway Over The Past 750 000 Years, Monica Winsborrow, Pengyang Song, Simon Belt, Jochen Knies, Henning A. Bauch, Lukas Smik, Gerrit Lohmann Jul 2025

Seasonal Sea Ice Characterized The Glacial Arctic-Atlantic Gateway Over The Past 750 000 Years, Monica Winsborrow, Pengyang Song, Simon Belt, Jochen Knies, Henning A. Bauch, Lukas Smik, Gerrit Lohmann

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 Jul 2025

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 …

Coastal communities have complex bodies of knowledge around environmental change, resilience, and sustainability, which extractive forms of research are not well suited to understand. This paper outlines an arts-based action research pilot project to understand social-ecological resilience in the Western Indian Ocean. Our project used visual, artistic, and participatory approaches to foster co-learning and action research on: (1) the arts-based methods themselves and (2) resilience building in coastal communities and ecosystems. This paper focuses on the former elements. We present our inherently phenomenological approach as a research assemblage that can be used to bring together different communities and stakeholders, disciplines, …

No One Acts Alone-Unravelling The Compositional Influences Of Organic Compounds In Offshore Produced Water On Zebrafish Embryotoxicity, Lisbet Sørensen, Paul Mccormack, Paul Sutton, Julia Farkas, Sonnich Meier, Steven J. Rowland, Trond Nordtug, Bjørn Henrik Hansen

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 …

Ngo Decision-Making During Typhoon Disaster Response: Towards A Relational Approach, Pamela Gloria Cajilig, Mona Nasser Jun 2025

Ngo Decision-Making During Typhoon Disaster Response: Towards A Relational Approach, Pamela Gloria Cajilig, Mona Nasser

Peninsula Dental School

This paper examines the decision-making processes of a non-governmental organisation (NGO) during Typhoon Odette (Rai) in Palawan, Philippines. The typhoon, which struck during the ongoing COVID-19 pandemic, exacerbated vulnerabilities in the province, leading to the destruction of homes and livelihoods, disruptions in education, fatalities and damage to critical infrastructure. Focusing on a health- and development-centred NGO, the qualitative case study draws from phenomenological approaches to decision-making and studies that emphasise relational ontologies. The discussion employs a framework that categorises decision-making into three types of processes that underscore the latter's entangled nature: ‘knot’ represents situations of confusion and desperation and where …

Distance and remoteness no longer pose barriers to conducting meaningful research, as the adaptation of participatory methods can address these challenges effectively. This article examines the transformation of the UniCDent Toolkit, originally designed to capture patients' perceptions of uncertainty in dental environments, for online participatory interactions with dentists. The toolkit, which uses the walking method, incorporates components such as imagery, gallery walks, quadrant mapping, and trade-offs to explore uncertainty in dental practice. Initially, dentists expressed discomfort in sharing their uncertainty in a group setting, prompting a shift to an online format that maintained participant engagement and created a safe space …

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.

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.

The Density Of Virgin, Consumer And Environmental Plastics: An Investigation Using Gas Displacement Pycnometry, Andrew Turner, Katie Jones, Montserrat Filella Jun 2025

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.

No Escape From Microplastics: Contamination Of Reef Manta Ray Feeding Areas In A Remote, Protected Archipelago, Jessica Savage, Joanna Harris, Heather J. Koldewey, Tom B. Letessier, M Rowcliffe, D Morritt

School of Biological and Marine Sciences

Remote islands receive plastic debris from elsewhere, ranging from microplastics (>5 mm) to macroplastics, which can further breakdown into microplastics. The ingestion of microplastics by marine species has been linked to decreased fitness. Reef manta rays, Mobula alfredi, are liable to ingest microplastics due to their filter-feeding strategy and habitat overlap with plastic hotspots. Their population is in decline due to unsustainable fishing pressures and a slow life history, with potential additional demographic pressure from plastic pollution. This study investigates the concentration and characteristics of microplastics in the top 0.5 m of the water column in reef manta rays …

Redefining The Photic Zone: Beyond The Autotroph-Centric View Of Light In The Ocean, Thomas Davies, Tim Smyth May 2025

Redefining The Photic Zone: Beyond The Autotroph-Centric View Of Light In The Ocean, Thomas Davies, Tim Smyth

School of Biological and Marine Sciences

Traditional measures of the photic zone have remained focused on autotrophs, limiting understanding of how changing marine lightscapes impact heterotrophs that use light as a resource or an environmental cue. We propose a new photic zone definition that encompasses all biological processes influenced by celestial light, and a new measure of photic zone depth, the minimum light intensity that elicits biological responses. This approach allows photic zone measures to be inclusive of all marine photobiology driven by sunlight, moonlight, or starlight, and enables urgently needed exploration of the nature, extent and ecological implications of changing marine lightscapes.

The accelerated development of urban agglomerations in China has resulted in the significant regional expansion of infrastructure and urban spaces, which has led to the fragmentation of habitats and the degradation of ecosystem function. Ecological networks have been shown to reconnect isolated habitat patches within urban agglomerations by identifying ecological sources and constructing corridors, which could enhance regional ecological security. Nature reserves, as critical areas for the protection of key species and ecosystems, play a vital role in this process. Investigating the influence of nature reserves on the ecological networks of urban agglomerations helps to integrate regional ecological resources, optimize …

Background: Diverse populations are more exposed to life course influences on adverse ageing, including brain ageing. Research into dementia in the United Kingdom inadvertently lacks diversity. Therefore, there is a need for more inclusive dementia research, developed in a way to ensure those who are currently missing from standard health data are represented. This may warrant the use of co-creation (emphasising collaborative creation and solution development), drawing on participatory methodologies in healthcare, research and service delivery. Methods: This study presents a scoping review of grey literature using Arksey and O’Malley’s methodology. Literature was sourced from the Patient Experience Library and …
