This fully funded PhD position at Northumbria University, as part of the Net Zero Polar Science Doctoral Training Partnership (NZPS DTP), offers a unique opportunity to investigate the feedbacks between Antarctic ice sheet retreat and volcanic activity, with a strong emphasis on reducing the carbon footprint of polar research. The project aims to clarify the mechanistic links between ice loss and enhanced volcanism in Antarctica, a process that could have significant implications for global climate models and future climate projections. Supervised by Dr. Jack Longman (Northumbria University), Prof. Hugh Tuffen (Lancaster University), and Dr. Ronja Reese (Northumbria University), the research will combine state-of-the-art ice sheet modelling with the analysis of sedimentary core-based records of volcanic activity. The successful candidate will have the opportunity to visit core repositories, create a database of volcanic ash layers in Southern Ocean sediments, and compare these records to modelled data on Antarctic ice sheet extent and thickness over the last deglaciation (~20,000 years). The project will focus particularly on the West Antarctic ice sheet and Pine Island Glacier, using model simulations and mantle melting models to clarify the feedbacks between ice retreat and volcanic activity. Technical approaches include constructing ice sheet load histories from existing modelling data (Parallel Ice Sheet Model coupled to 3D Viscoelastic Lithosphere and Mantle model), applying novel methods for identifying ash layers in sediment cores, and developing magma chamber models tuned with actual ice load data. The project will also quantify the carbon footprint reduction achieved by re-using model output data and already-collected samples, as opposed to traditional carbon-intensive fieldwork and supercomputer-based modelling. Training opportunities are extensive, including collaboration with PISM modellers at the Max-Planck-Institute for Geoanthropology (Germany) and the possibility to develop magma chamber modelling with colleagues at Brown University (USA). Fieldwork will focus on describing already-collected sediment cores, and the student will gain skills in numerical modelling, data analysis, and environmental science. Applicants should hold a first or upper second (2:1) class honours undergraduate degree in geology, physical geography, physics, mathematics, or a related field, or an equivalent international qualification. A relevant master’s qualification or equivalent professional practice is also accepted. While prior knowledge of volcanology or glaciology is advantageous, it is not required. International applicants and those from non-English speaking countries must meet the minimum language requirements for their Home institution. Funding is available to Home/UK and international (including EU) students, subject to quality assurance and UKVI compliance. The studentship includes a full stipend at UKRI rates (£20,780 per year for 2025/26), full tuition fees, and an annual Research Training and Support Grant (RTSG). Part-time studentships are available for Home applicants. Additional costs may apply for international applicants. The application deadline is 12th January 2026 (09:00 GMT). Interested candidates should contact Dr Jack Longman ([email protected]) for informal enquiries, complete the online NZPS Application Form, and submit any additional documents to [email protected] by the closing date.

This fully funded PhD opportunity at Northumbria University, as part of the Net Zero Polar Science Doctoral Training Partnership (NZPS DTP), aims to advance our understanding of the feedbacks between Antarctic ice sheet retreat and volcanic activity, while reducing the carbon footprint of polar research. The project addresses a critical gap in climate science: how the loss of ice in Antarctica may trigger increased volcanic activity, which in turn could accelerate atmospheric warming and further ice loss. Despite evidence for over 100 potentially active volcanoes beneath the West Antarctic ice sheet, this feedback mechanism is not yet considered in major climate models such as those used by the IPCC. The research will combine state-of-the-art ice sheet modelling with the analysis of sedimentary core records to reconstruct past volcanic activity and its relationship to ice volume changes over the last deglaciation (~20,000 years). You will have the opportunity to visit core repositories, create a database of volcanic ash layers in Southern Ocean sediments, and compare these records to modelled ice sheet data. The project will focus on the West Antarctic ice sheet, particularly the Pine Island Glacier, using model simulations and mantle melting models to clarify the mechanistic links between ice retreat and volcanism. Technical approaches include constructing ice sheet load histories from existing modelling data (Parallel Ice Sheet Model coupled to 3D Viscoelastic Lithosphere and Mantle model), applying novel methods for identifying volcanic ash layers in sediment cores, and developing magma chamber models tuned with actual ice load data. For the first time, future projections with ice sheet models will be analysed in relation to volcanic activity, providing new insights into potential climate feedbacks. Importantly, this project will quantify the carbon footprint reduction achieved by re-using model output data and already-collected samples, as opposed to traditional carbon-intensive methods such as ship-based fieldwork and supercomputer modelling. Training will be provided in numerical modelling, in collaboration with PISM modellers at the Max-Planck-Institute for Geoanthropology (Germany), and there is potential to develop magma chamber modelling with colleagues at Brown University (USA). Fieldwork will focus on describing existing sediment cores rather than new sample collection. Applicants should have a strong academic background in geology, physical geography, physics, or mathematics. Experience in volcanology or glaciology is beneficial but not essential. Entry requirements include a first or upper second class honours degree (or equivalent international qualification) in a relevant subject, or a relevant master's qualification or equivalent professional practice.
