Water quality is a key consideration for both socio-economic and environmental sustainability (UN Sustainable Development Goal 6: Clean Water and Sanitation). However due to both natural and anthropogenic pressures, water quality is known to be threatened in many regions around the world. In this GCRF funded project, Nuestro Rio (“Our River”), we focus on water quality across the Santa River basin in Peru. To gain insights into water quality perspectives in upstream rural regions as well as downstream, urban regions in the Santa Basin, we designed and launched a citizen science app to assess community perceptions and collect images of …

Since the Millennium Ecosystem Assessment in 2005, interest has increased in cultural ecosystem services (CESs) research to understand the complexity of the non-material benefits that people obtain from ecosystems. The intangible and interactive characteristics of CESs present many challenges regarding how to approach, quantify and even define CESs. In this paper, we suggest looking at CESs through the lens of embodied and situated cognition theories. We advocate that such an approach should be applied to the development stage of CES research projects, as the embodied and situated experience of the site aids the development of research questions and future interventions. …

Samples of fresh snow (n = 34) have been collected from 29 locations in various urban and remote regions of northern Iran following a period of sustained snowfall and the thawed contents examined for microplastics (MPs) according to established techniques. MP concentrations ranged from undetected to 86 MP L−1 (mean and median concentrations ~20 MP and 12 MP L−1, respectively) and there was no significant difference in MP concentration between sample location type or between different depths of snow (or time of deposition) sampled at selected sites. Fibres were the dominant shape of MP and μ-Raman spectroscopy of selected samples …

Pbdes In The Marine Environment: Sources, Pathways And The Role Of Microplastics, Andrew Turner
School of Geography, Earth and Environmental Sciences
Brominated flame retardants (BFRs) are an important group of additives in plastics that increase resistance to ignition and slow down the rate of burning. Because of concerns about their environmental and human health impacts, however, some of the most widely employed BFRs, including hexabromocyclododecane (HBCD) and commercial mixtures of penta-, octa- and deca- (poly)bromodiphenyl ethers (PBDEs), have been restricted or phased out. In this review, the oceanic sources and pathways of PBDEs, the most widely used BFRs, are evaluated and quantified, with particular focus on emissions due to migration from plastics into the atmosphere versus emissions associated with the input …

School of Geography, Earth and Environmental Sciences
Analysis of state identity constructions can provide important insights into the ideologies, values, ambitions and policies of influential state actors. Existing research on state identities has focused mainly on how such identities are constructed and utilised within domestic politics or conventional inter-state/international relations but limited attention has been paid to how states construct their identities in relation to, and through, overseas territories that occupy liminal positions of sovereignty. This article addresses this gap by investigating how state actors have discursively constructed the UK’s identities through the lens of environmental protection in the UK’s overseas territories. It analyses UK parliamentary debate …
The Occurrence Of Monoclinic Jarosite In Natural Environments, N Stephen, A Whitworth
The Occurrence Of Monoclinic Jarosite In Natural Environments, N Stephen, A Whitworth
School of Geography, Earth and Environmental Sciences
Jarosite and related subgroup minerals are of high importance in mineral processing, as sources and sinks for metals and acidity in the environment, and they have the potential to preserve elemental and isotopic biomarkers relevant to the search for life in the solar system. The crystal structures and chemistry of jarosite minerals affect their stability and reactivity and thus the roles they play in natural and engineered systems. Rhombohedral symmetry has been documented in natural and synthetic jarosites, whereas monoclinic symmetry has only been documented in synthetic jarosites. This research reports the occurrence of monoclinic symmetry in a natural natrojarosite …

The Southern Ocean paleoceanography provides key insights into how iron fertilization and oceanic productivity developed through Pleistocene ice-ages and their role in influencing the carbon cycle. We report a high-resolution record of dust deposition and ocean productivity for the Antarctic Zone, close to the main dust source, Patagonia. Our deep-ocean records cover the last 1.5 Ma, thus doubling that from Antarctic ice-cores. We find a 5 to 15-fold increase in dust deposition during glacials and a 2 to 5-fold increase in biogenic silica deposition, reflecting higher ocean productivity during interglacials. This antiphasing persisted throughout the last 25 glacial cycles. Dust …

Abstract. Quantitative reconstructions of past land cover are necessary to determine the processes involved in climate–human–land-cover interactions. We present the first temporally continuous and most spatially extensive pollen-based land-cover reconstruction for Europe over the Holocene (last 11 700 cal yr BP). We describe how vegetation cover has been quantified from pollen records at a 1∘ × 1∘ spatial scale using the “Regional Estimates of VEgetation Abundance from Large Sites” (REVEALS) model. REVEALS calculates estimates of past regional vegetation cover in proportions or percentages. REVEALS has been applied to 1128 pollen records across Europe and part of the eastern Mediterranean–Black Sea–Caspian …

Abstract Swamps are a highly significant wetland type in North America both in terms of areal extent and their role in terrestrial carbon cycling. These wetlands, characterized by woody vegetation cover, encompass a diverse suite of ecosystems, including broad-leaved, needle-leaved, mixedwood or shrub/thicket swamps. Uncertainties in the role of swamps in carbon uptake and release continue to be substantial due to insufficient data on variabilities in carbon densities across diverse swamp types and relatively few flux measurements from swamp sites. Robust measurements of rates of vertical accretion of swamp soils and the associated long-term rates of carbon accumulation, alongside measurements …

Dust storms are common events in arid and semi-arid regions that have a wide range of impacts on the environment and human health. This study addresses the presence, characteristics and potential sources of microplastics (MPs) in such events by analysing MPs deposited with dust particles in the metropolis of Shiraz, southwest Iran, following an intense storm in May 2018. At 22 locations throughout the city, MP concentrations on a number basis ranged from 0.04 to 1.06 per g of dust (median = 0.31 MP g−1). Particles were mainly fibrous, with a mean diameter of about 20 μm and >60% under …

Airborne particulate matter (PM) with an aerodynamic size cutoff of 10 µm (PM10) has been collected using a high volume air sampler at two locations (urban and residential) in the city of Ahvaz, Iran, for sixteen 24-hour periods over four months (late summer to early winter). Microplastics (MPs) in the PM were isolated after sample digestion and were subsequently characterised by established techniques. All MPs sampled (n = 322) were of a fibrous nature, with polyethylene terephthalate, nylon and polypropylene being the dominant polymers and consistent with textiles and fabrics as the principal source. Despite a distinct seasonality (temperature and …

Anchoring Policies, Alignment Tensions: Reconciling New Zealand’S Climate Change Act And Emissions Trading Scheme, Tor Håkon Jackson Inderberg, Ian Bailey
School of Geography, Earth and Environmental Sciences
Climate Change Acts (CCAs) seek to anchor national climate policy by establishing long-term targets and lines of accountability that guide the development of other climate policy instruments. However, counter-pressures to modify CCAs can occur where tensions exist with the provisions of already-established policies that enjoy substantial political and stakeholder support. Such tensions can be especially pronounced where CCAs necessitate major changes to emissions trading schemes (ETSs) that have formed the mainstay of efforts to reduce national emissions. This article employs a novel anchoring policy framework to examine the dynamics of aligning ETSs with CCAs. We investigate debates on reforms to …

School of Geography, Earth and Environmental Sciences
Editorial on the Research TopicRe-Purposing Universities for Sustainable Human ProgressHumanity is confronting the most acute and urgent threat it has ever consciously faced. Soaring inequality, accelerating climate crises, ecological collapse, and social and psychological breakdown represent a multi-faceted socio-ecological crisis that is threatening viability of life on Earth. The undeniable evidence of this is fueling a growing global recognition that something has gone badly wrong with the ways in which our society has sought to optimize its wellbeing and that of non-human life which it brings into its ethical sphere of care. But what is the culpability of universities in …

Subaerial Volcanism Is A Potentially Major Contributor To Oceanic Iron And Manganese Cycles, Jack Longman, Martin R. Palmer, Thomas M. Gernon, Hayley R. Manners, Morgan T. Jones
School of Geography, Earth and Environmental Sciences
Surface ocean availability of the micronutrients iron and manganese influences primary productivity and carbon cycling in the ocean. Volcanic ash is rich in iron and manganese, but the global supply of these nutrients to the oceans via ash deposition is poorly constrained. Here, we use marine sediment-hosted ash composition data from ten volcanic regions, and subaerial volcanic eruption volumes, to estimate global ash-driven nutrient fluxes. Using Monte Carlo simulations, we estimate average fluxes of dissolved Iron and Manganese from volcanic sources to be between 50 and 500 (median 180) and 0.6 and 3.2 (median 1.3) Gmol yr−1, respectively. Much of …

School of Geography, Earth and Environmental Sciences
This study analyses the morphological changes induced by eruptive activity at Stromboli volcano (Italy) during and after events occurring during July–August 2019. This period was characterized by intense eruptive activity (two paroxysmal explosions, a two-month-long lava emission, and more intense and frequent “ordinary” explosive activity) that produced significant changes within the region known as Sciara del Fuoco, located on the most unstable, north-western flank of the volcano. Since September 2019, the eruptive activity waned but remained intense, and erosive phenomena continued to contribute to the re-shaping of the Sciara del Fuoco. The morphological changes described here were documented by integrating …

Abstract. The Collisional Orogeny in the Scandinavian Caledonides (COSC) scientific drilling project aims to characterise the structure and orogenic processes involved in a major collisional mountain belt by multidisciplinary geoscientific research. Located in western central Sweden, the project has drilled two fully cored deep boreholes into the bedrock of the deeply eroded Early Paleozoic Caledonide Orogen. COSC-1 (2014) drilled a subduction-related allochthon and the associated thrust zone. COSC-2 (2020, this paper) extends this section deeper through the underlying nappes (Lower Allochthon), the main Caledonian décollement, and the upper kilometre of basement rocks. COSC-2 targets include the characterisation of orogen-scale detachments, …

AbstractThe Black Death (1347–1352 ce) is the most renowned pandemic in human history, believed by many to have killed half of Europe’s population. However, despite advances in ancient DNA research that conclusively identified the pandemic’s causative agent (bacterium Yersinia pestis), our knowledge of the Black Death remains limited, based primarily on qualitative remarks in medieval written sources available for some areas of Western Europe. Here, we remedy this situation by applying a pioneering new approach, ‘big data palaeoecology’, which, starting from palynological data, evaluates the scale of the Black Death’s mortality on a regional scale across Europe. We collected pollen …

Climate change has great impacts on forest ecosystems, especially with the increasing frequency of heatwaves. Thermal safety margin (TSM) calculated by the difference between body temperature and thermotolerance threshold is useful to predict thermal safety of organisms. It has been widely used for animals, whereas has rarely been reported for plants. Besides, most of the previous studies used only thermotolerance to estimate thermal safety or used thermotolerance and air temperature (Ta) to calculate TSM. However, leaf temperature (Tl) is the real "body" temperature of plant leaves. Tl decoupling from Ta might induce large error in TSM. Here, we investigated TSM …

Occurrence And Chemical Characteristics Of Microplastic Paint Flakes In The North Atlantic Ocean, Andrew Turner, Clare Ostle, Marianne Wootton
School of Geography, Earth and Environmental Sciences
Non-fibrous microplastics sampled by the Continuous Plankton Recorder (CPR) Survey throughout the North Atlantic Ocean during 2018 have been recorded and a selection (n = 17, or 16.7%) physically and chemically characterised. The average abundance of non-fibrous particles captured by the plankton silks and detectable by microscopy was estimated to be around 0.01 m-3, with the highest concentrations evident in shelf seas of northwest Europe. Amongst the samples analysed, median size was 180 μm and, based on visible properties (e.g., brittleness, layering) and infra-red spectra, all but one were identified as flakes of paint. Semi-quantitative analysis by energy-dispersive X-ray fluorescence …

Poleward range shifts are a global-scale response to warming, but these vary greatly among taxa and are hard to predict for individual species, localized regions or over shorter (years to decadal) timescales. Moving poleward might be easier in the Arctic than in the Southern Ocean, where evidence for range shifts is sparse and contradictory. Here, we compiled a database of larval Antarctic krill, Euphausia superba and, together with an adult database, it showed how their range shift is out of step with the pace of warming. During a 70-year period of rapid warming (1920s–1990s), distribution centres of both larvae and …
Endotyping Asthma - Profiling The Metabolic Dimension?, Michael J. Wilde, Salman Siddiqui
Endotyping Asthma - Profiling The Metabolic Dimension?, Michael J. Wilde, Salman Siddiqui
School of Geography, Earth and Environmental Sciences
Asthma has long been recognised as a heterogeneous disease, and the notion of discrete endotypes of asthma has been prevalent for over a decade [1]. However, despite the success in identifying and targeting type-2 inflammation in asthma, the identification of tractable endotypes - has remained elusive; with not a single endotype defined with certainty. Here, Kelly et al, have reported putative novel asthma endotypes, defined using metabolomics (metabo-endotypes), in childhood asthma [2]. The metabolomics included unbiased multi-platform, metabolic profiling, using liquid chromatography and tandem mass spectrometry (LC-MS). The metabolic endotypes generated, were replicated against clinical outcomes in an independent cohort, …
