Thousands of artificial (‘human-made’) structures are present in the marine environment, many at or approaching end-of-life and requiring urgent decisions regarding their decommissioning. No consensus has been reached on which decommissioning option(s) result in optimal environmental and societal outcomes, in part, owing to a paucity of evidence from real-world decommissioning case studies. To address this significant challenge, we asked a worldwide panel of scientists to provide their expert opinion. They were asked to identify and characterise the ecosystem effects of artificial structures in the sea, their causes and consequences, and to identify which, if any, should be retained following decommissioning. …

Complex Erosional Response To Uplift And Rock Strength Contrasts In Transient River Systems Crossing An Active Normal Fault Revealed By 10Be And 26Al Cosmogenic Nuclide Analyses, Sarah J. Boulton, Ángel Rodés, Derek Fabel, M. Cihat Alçiçek, Alexander C. Whittaker Feb 2024

Complex Erosional Response To Uplift And Rock Strength Contrasts In Transient River Systems Crossing An Active Normal Fault Revealed By 10Be And 26Al Cosmogenic Nuclide Analyses, Sarah J. Boulton, Ángel Rodés, Derek Fabel, M. Cihat Alçiçek, Alexander C. Whittaker

School of Geography, Earth and Environmental Sciences

Understanding the influence of bedrock lithology on the catchment-averaged erosion rates of normal fault-bounded catchments and the effect that different bedrock erodibilties have on the evolution of transient fluvial geomorphology remain major challenges. To investigate this problem, we collected 18 samples for 10Be and 26Al cosmogenic nuclide analysis to determine catchment-averaged erosion rates along the well-constrained Gediz Fault system in western Türkiye, which is experiencing fault-driven river incision owing to a linkage event ~0.8 Ma and has weak rocks overlying strong rocks in the footwall. Combined with existing cosmogenic data, we show that the background rate of erosion …

A Relational Approach To Knowledge Exchange In Higher Education, Harriet Dismore, Verity Campbell-Barr, Rachel Manning, Paul Warwick Feb 2024

A Relational Approach To Knowledge Exchange In Higher Education, Harriet Dismore, Verity Campbell-Barr, Rachel Manning, Paul Warwick

School of Law, Humanities and Social Sciences

Reference to Knowledge Exchange (KE) in UK Higher Education Institutions (HEIs) has become common place, reflecting the continued changing role of universities within society. Arguably, KE draws together notions of HEIs as purveyors of knowledge, with students helping to create a tripartite relationship with HEIs and the wider community as well as a civic responsibility to contribute to the wider public good. Realising the potential benefits of this inter-relationship required a problematising of the meanings of both knowledge and the notion of an exchange, drawing on the work of Dewey and Bernstein. Our paper offers an analysis of the different …

Cigarette Filter Fibres As A Source And Sink Of Trace Metals In Coastal Waters, Andrew Turner, Abigail Louise Cundell Feb 2024

Cigarette Filter Fibres As A Source And Sink Of Trace Metals In Coastal Waters, Andrew Turner, Abigail Louise Cundell

School of Geography, Earth and Environmental Sciences

Cellulose acetate fibres from cigarette filters represent a form of microplastic that has received little attention in the environment. In this study, a ground composite of spent, smoked filter material (FM) has been used to investigate the role of cellulose acetate fibres as a source and a sink of trace metals (Cd, Co, Cu, Ni, Pb and Zn) in coastal waters. FM suspended in river water and seawater and mixtures thereof representative of an estuarine gradient resulted in the leaching of pre-existent metals derived from the combustion of tobacco, with mean percentages of release ranging from about 40 for Pb …

A healthy marine ecosystem is a fully functioning system, able to supply ecosystem services whilst still maintaining resilience to human-induced environmental change. Monitoring and managing the health of resilient marine ecosystems requires indicators that can assess their biodiversity state and food web functioning. Plankton are crucial components of pelagic habitats, occupying the base of the pelagic food web. Larger plankton have long been used to monitor ecosystem productivity and biodiversity due to their identification via traditional light microscopy. In contrast, the regular monitoring of pico- and nanoplankton (<20 µm; hereafter called “tiny plankton”) only started with the development of flow cytometry techniques, which has limited their inclusion as ecosystem health indicators. Four UK plankton surveys have sampled and identified these tiny plankton for up to 14 years, providing an opportunity to test their suitability as indicators of ecosystem state. We investigated six groups of tiny plankton, including heterotrophic nanoeukaryotes, photosynthetic nanoeukaryotes, photosynthetic picoeukaryotes, and Synechococcus cyanobacteria, and two groups of heterotrophic bacteria. Flow cytometry and light microscopy data from an inshore Western English Channel station revealed that 99.98 % of plankton abundance and 71 % of plankton biomass was derived from tiny plankton cells too small to be quantified accurately under a light microscope and thus not adequately considered in assessments of pelagic habitats. Different UK marine and coastal regions showed consistency in peak abundances of these tiny plankton. We used a novel wavelet coherence method to identify time-based relationships between tiny plankton and environmental variables linked to human pressures. Relationships were found between nitrogenous nutrients and all tiny plankton groups, most commonly at sub-annual to annual time scales. Photosynthetic picoeukaryotes, heterotrophic nanoeukaryotes, and HNA-bacteria were associated with high sea surface temperatures. Given the here established relationship between tiny plankton and environmental variables, and their importance in the full plankton assemblage, we recommend that, alongside existing microplankton lifeforms, tiny plankton groups can be used as plankton lifeforms, either individually or in combination, to inform biodiversity indicators that meet policy obligations under the EU Marine Strategy Framework Directive (MSFD), (Oslo-Paris Convention) OSPAR strategies, and the UK Marine Strategy.

Microplastic Trapping Efficiency And Hydrodynamics In Model Coral Reefs: A Physical Experimental Investigation, F Mendrik, Rc Houseago, Cr Hackney, Dr Parsons Feb 2024

Microplastic Trapping Efficiency And Hydrodynamics In Model Coral Reefs: A Physical Experimental Investigation, F Mendrik, Rc Houseago, Cr Hackney, Dr Parsons

School of Biological and Marine Sciences

Coastal ecosystems, such as coral reefs, are vulnerable to microplastic pollution input from proximal riverine and shoreline sources. However, deposition, retention, and transport processes are largely unevaluated, especially in relation to hydrodynamics. For the first time, we experimentally investigate the retention of biofilmed microplastic by branching 3D printed corals (staghorn coral Acropora genus) under various unidirectional flows (U = {0.15, 0.20, 0.25, 0.30} ms −1) and canopy densities (15 and 48 corals m −2). These variables are found to drive trapping efficiency, with 79–98% of microplastics retained in coral canopies across the experimental duration at high flow velocities …

Nutritional Requirements And Effect Of Culture Conditions On The Performance Of The African Catfish (Clarias Gariepinus): A Review, Sandra Langi, Sahya Maulu, Oliver J. Hasimuna, Veronica Kaleinasho Kapula, Martin Tjipute

School of Biological and Marine Sciences

Aquaculture is crucial for global food and nutrition security due to the inability of wild harvests to meet increasing demand. Africa’s contribution to aquaculture is generally low, despite its potential for economic development, food security, and reduced unemployment. The study focuses on the African catfish (Clarias gariepinus) a freshwater fish species that is widely farmed for food in Africa and other parts of the world. Proper nutrition is essential for the growth and development of the fish, and understanding their nutritional requirements is critical for producing healthy and high-quality fish.

Microplastic Transport And Deposition In A Beach-Dune System (Saunton Sands-Braunton Burrows, Southwest England), Rachael J. Anderson, Andrew Turner Jan 2024

Microplastic Transport And Deposition In A Beach-Dune System (Saunton Sands-Braunton Burrows, Southwest England), Rachael J. Anderson, Andrew Turner

School of Geography, Earth and Environmental Sciences

Although microplastics (MPs) are ubiquitous contaminants that have been extensively studied in the marine setting, there remain gaps in our understanding of their transport and fate in the coastal zone. In this study, MPs isolated from surface sediments sampled from a large beach-dune complex in southwest England have been quantified and characterised. Concentrations above a detectable size limit of 30 to 50 μm ranged from about 40 to 560 MP kg−1 dry weight but, despite local sources of plastics such as an estuary and seasonal tourism, there were no significant differences in median concentrations between different orthogonal foreshore transects and …

Locked Out? Navigating The Geographies Of Precarity On Britain's Waterways, Agatha Herman, Richard Yarwood Jan 2024

Locked Out? Navigating The Geographies Of Precarity On Britain's Waterways, Agatha Herman, Richard Yarwood

School of Geography, Earth and Environmental Sciences

Motivations for living on the UK's waterways range from lifestyle to financial, but increasing numbers have been pushed aboard in response to current, and longstanding, cost-of-living and housing crises. However, while more affordable than living on land, our qualitative investigation reveals a diversity of practices and experiences of marginalisation on the waterways, drawing out the impacts of temporal and spatial fluidity to inform our understanding of precarity in a mobile world. The waterways are a contested and politicised space with diverse actors seeking to delineate legitimate practices and users. Liveaboard boaters practice residential subjectivities in what others designate as leisure …

Switching from fossil fuels to renewable energy is key to international energy transition efforts and the move toward net zero. For many nations, this requires decommissioning of hundreds of oil and gas infrastructure in the marine environment. Current international, regional and national legislation largely dictates that structures must be completely removed at end-of-life although, increasingly, alternative decommissioning options are being promoted and implemented. Yet, a paucity of real-world case studies describing the impacts of decommissioning on the environment make decision-making with respect to which option(s) might be optimal for meeting international and regional strategic environmental targets challenging. To address this …

Large explosive volcanic eruptions from island arcs pour pyroclastic currents into marine basins, impacting ecosystems and generating tsunamis that threaten coastal communities and infrastructures. Risk assessments require robust records of such highly hazardous events, which is challenging as most of the products lie buried under the sea. Here we report the discovery by IODP Expedition 398 of a giant rhyolitic pumice deposit emplaced 520 ± 10 ky ago at water depths of 200 to 1000 m during a high-intensity, shallow submarine eruption of ancestral Santorini Volcano. Pyroclastic currents discharged into the sea transformed into turbidity currents and slurries, forming a …

Moral Mobilization In The Digital Space: Seafarers Exercising Agency During The Pandemic, Lijun Tang

Plymouth Business School

The agency of casualized and spatially isolated workers has recently received increased research attention. This paper extends this line of research to seafarers, a traditional but also casualized and spatially isolated workforce. More specifically, it examines cases of collective action by Chinese seafarers on WeChat, a social media platform, in response to problems and grievances caused by COVID-19 control measures during the pandemic. It shows that seafarers, building on the WeChat platform and together with other maritime stakeholders, have established a socio-technological infrastructure that enables them to mobilize their peers to take action when they experience injustice at work. Their …

Sea Ice-Ocean Coupling During Heinrich Stadials In The Atlantic–Arctic Gateway, Naima El Bani Altuna, Mohamed M. Ezat, Lukas Smik, Francesco Muschitiello, Simon T. Belt, Jochen Knies, Tine L. Rasmussen

School of Geography, Earth and Environmental Sciences

The variability of Arctic sea-ice during abrupt stadial-interstadial shifts in the last glacial period remain poorly understood. Here, we investigated the millennial-scale relationship, with a focus on Heinrich Stadials (HS), between sea-ice cover and bottom water temperature (BWT) during Marine Isotope Stages (MIS) 3 and 2 (64–13 ka) in the Fram Strait using new molecular sea ice biomarker data and published benthic foraminiferal BWT records. Widespread spring sea-ice cover (SpSIC) dominated the studied interval, especially in mid-late MIS 3 (45–29 ka). Yet, warm interstadials were characterized by relatively more open-ocean conditions compared to cold stadials. At the transition between a …

Steeper Size Spectra With Decreasing Phytoplankton Biomass Indicate Strong Trophic Amplification And Future Fish Declines, Angus Atkinson, Axel G. Rossberg, Ursula Gaedke, Gary Sprules, Ryan F. Heneghan, Stratos Batziakas, Maria Grigoratou, Elaine Fileman, Katrin Schmidt, Constantin Frangoulis Jan 2024

Steeper Size Spectra With Decreasing Phytoplankton Biomass Indicate Strong Trophic Amplification And Future Fish Declines, Angus Atkinson, Axel G. Rossberg, Ursula Gaedke, Gary Sprules, Ryan F. Heneghan, Stratos Batziakas, Maria Grigoratou, Elaine Fileman, Katrin Schmidt, Constantin Frangoulis

School of Geography, Earth and Environmental Sciences

Under climate change, model ensembles suggest that declines in phytoplankton biomass amplify into greater reductions at higher trophic levels, with serious implications for fisheries and carbon storage. However, the extent and mechanisms of this trophic amplification vary greatly among models, and validation is problematic. In situ size spectra offer a novel alternative, comparing biomass of small and larger organisms to quantify the net efficiency of energy transfer through natural food webs that are already challenged with multiple climate change stressors. Our global compilation of pelagic size spectrum slopes supports trophic amplification empirically, independently from model simulations. Thus, even a modest …

Characteristics Of Active Deformation, Fault Interaction, And Earthquake Triggering In A Rapidly-Deforming Complex Normal Fault Network (South-West Türkiye), Manuel-Lukas Diercks Jan 2024

Characteristics Of Active Deformation, Fault Interaction, And Earthquake Triggering In A Rapidly-Deforming Complex Normal Fault Network (South-West Türkiye), Manuel-Lukas Diercks

School of Geography, Earth and Environmental Sciences Theses

Despite often being overshadowed by disastrous earthquakes on subduction zones and continental transform faults, normal faulting earthquakes frequently cause severe destruction and casualties. Understanding earthquake occurrence and determining those faults most at risk of rupturing in destructive earthquakes is crucial to prevent disasters. A key approach to understanding earthquake occurrence is to understand how stress and strain develop through a fault system over the earthquake cycle. In this thesis, Coulomb stress modelling, SAR interferometry, and field work are combined with a comprehensive literature review to study active deformation, fault interactions, and earthquake triggering mechanisms in complex normal fault networks, with …

Landscapes Of Play: An Exploration And Illumination Of Children’S Unsupervised Play Close To Home And A Researcher’S Journey To Becoming Posthuman., Mandy Andrews

School of Law, Humanities and Social Sciences Theses

Title: Landscapes of Play: An exploration and illumination of children’s unsupervised play close to home and a researcher’s journey to becoming posthuman. Author: Mandy Jo Andrews This thesis explores children’s play experiences and engagements out of doors close to home. Adopting a Deleuzian informed posthumanism the researcher’s journey towards immanence prompts re-thinking about play, childhood-nature entanglements, and play-space-place-player generation. Children’s unsupervised play outside of organised settings such as school or adventure playgrounds is less researched than that of organised settings. This thesis puts to work Deleuze’s process philosophy and Barad’s agential realism, together with Haraway’s biology informed multispecies manifesto, Bennett’s …

Contrasting Species-Specific Stress Response To Environmental Ph Determines The Fate Of Coccolithophores In Future Oceans, Nishant Chauhan, Craig J. Dedman, Chloë Baldreki, Adam A. Dowle, Tony R. Larson, Rosalind E.M. Rickaby

School of Geography, Earth and Environmental Sciences

Molecular mechanisms driving species-specific environmental sensitivity in coccolithophores are unclear but crucial in understanding species selection and adaptation to environmental change. This study examined proteomic and physiological changes in three species under varying pH conditions. We showed that changing pH drives intracellular oxidative stress and changes membrane potential. Upregulation in antioxidant, DNA repair and cell cycle-related protein-groups indicated oxidative damage across high (pH 8.8) and low pH (pH 7.6) compared to control pH (pH 8.2), and correlated with reduced growth rates. Upregulation of mitochondrial proteins suggested higher metabolite demand for restoring cellular homeostasis under pH-induced stress. Photosynthetic rates generally correlated …

A Delicate Matter: The Madhouses Of The South West Of England, 1770 – 1851, Emma Barrett Jan 2024

A Delicate Matter: The Madhouses Of The South West Of England, 1770 – 1851, Emma Barrett

School of Law, Humanities and Social Sciences Theses

This thesis examines the private madhouses of Somerset, Dorset, Devon, and Wiltshire during a period of great transition within the existing lunacy care landscape. Many madhouses pre-dated county asylums in provision for the pauper mentally ill, including in the south west. Madhouses operated as an enterprise, unlike the parish overseen county asylums. This led to a lack of regulations in care. The Lunacy Commission was formed as part of the 1828 Madhouse Act. This led to a series of inspections of all asylums throughout England for the first time. At this time, Devon and Somerset had disproportionally high rates of …

Microalgae are the main source of the omega‐3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), essential for the healthy development of most marine and terrestrial fauna including humans. Inverse correlations of algal EPA and DHA proportions (% of total fatty acids) with temperature have led to suggestions of a warming‐induced decline in the global production of these biomolecules and an enhanced importance of high latitude organisms for their provision. The cold Arctic Ocean is a potential hotspot of EPA and DHA production, but consequences of global warming are unknown. Here, we combine a full‐seasonal EPA and DHA dataset …

The deposition of volcanic ash into the ocean initiates a range of chemical and biological reactions. During diagenesis, these reactions may enhance the preservation of organic carbon (OC) in marine sediments, which ultimately promotes CO2 sequestration from the ocean-atmosphere system. However, this interpretation is reliant on a small number of studies that make a link between tephra and OC burial. Here, we compare organic and inorganic geochemical data from tephra-bearing marine sediments from three sites that differ widely in their location, age, and composition. We show that OC is buried in, and proximal to, tephra layers, in proportions higher than …

Quantifying interseismic deformation of fault networks which are predominantly deforming in a north-south direction is challenging, because GNSS networks are usually not dense enough to resolve deformation at the level of individual faults. The alternative, interferometric synthetic aperture radar (InSAR), provides high spatial resolution but is limited by a low sensitivity to N-S motion. We study the active normal fault network of Western Türkiye, which is undergoing rapid N-S extension, using InSAR. Since most faults in the study region are normal faults, we overcome the low N-S sensitivity by focusing on the vertical deformation component, which presents its own challenges. …
