Novel methods in applied physical volcanology, such as expert elicitation, and hazard and risk assessment, developed mostly during the ongoing volcanic crisis at Soufrière Hills Volcano (Montserrat), continues to inform decision making, worker and public safety, and management of administrative hazard zones that control access. These methodologies have been adopted worldwide using Montserrat Volcano Observatory (MVO) as an exemplar by the World Organisation of Volcano Observatories (WOVO). Bristol researchers have advised on institutional programmes and informed international agencies, such as the United Nations and the World Bank, to reduce risk presented by volcanic hazards, and save lives. Such is the impact of Bristol's work at MVO it has been studied by up to nearly one million school children in the UK since 2008.
The Zambian Copperbelt is the largest known repository of copper on Earth. Research at the University of Southampton has transformed the exploration landscape in the region, providing the world's mining companies with new opportunities for mineral exploration in Zambia and other sedimentary basins in Africa. This inward investment has contributed to rapid economic growth in Zambia and boosted local employment. Southampton's research model has contributed to the discovery of two world class copper deposits, impacted on the earnings of global mining companies, as well as ensuring a flow of highly skilled geologists from academia to industry.
Platinum Group Elements (PGE) are critical strategic metals because of their unrivalled applications in catalysts, fuel cells and electronics and cancer therapies. Research and analytical methods developed at Cardiff have impacted on exploration for new PGE deposits, and more efficient processing of PGE ores by international mining companies. A key milestone between 2009 and 2012 was the discovery of a 3 billion year old giant impact crater in West Greenland. This discovery is of major economic significance because all craters previously found in this size class are associated with multi-billion dollar mineral and/or hydrocarbon resources. It led to an intellectual property transaction worth CDN$ 2.1 million and discovery of nickel and PGE deposits in Greenland by North American Nickel Incorporated.
The ash cloud from the eruption of Iceland's Eyjafjallajökull volcano in 2010 caused the cancellation of over 100,000 flights and cost an estimated £3 billion. The much larger eruption of Grimsvötn (also in Iceland) the following year caused only 900 flights to be cancelled and its economic cost was around one per cent of that associated with the Eyjafjallajökull eruption. A key factor in this huge reduction was the improved understanding of ash clouds provided by researchers at the University of Bristol. Drawing on research conducted over two decades and immediately after the Eyjafjallajökull eruption, the Bristol team were able to inform and advise airlines and major decision-makers such as the Civil Aviation Authority, the UK Government and the European Space Agency. The input has since had a beneficial impact around the globe and has directly affected decisions and research strategies made by the Met Office and Rolls-Royce regarding operational developments associated with volcanic ash monitoring and forecasting.
Measurements of sulphur dioxide emissions from volcanoes provide critical evidence for forecasting eruptions. From 2001 the research team led by Clive Oppenheimer (Department of Geography, University of Cambridge: Lecturer 1994-2003; Reader 2003-12; Professor 2012-) has shown that a new technique based on UV spectroscopy can revolutionise such measurements. The approach (awarded a US patent in 2006) has since 2008 come to underpin the state-of-the-art in operational surveillance of volcanic emissions worldwide, contributing significantly to hazard assessment and emergency management at over thirty volcanoes, and helping to save lives by providing early warning. The team has trained and supported volcanologists around the world in the methodology (in Costa Rica, 2008; Java, 2010; Iceland, 2012), and has helped in collecting data during volcanic crises (e.g. Merapi, 2010), contributing to planning decisions and the safety of local populations.
Durham research on hydraulic fracturing was an important part of the UK government's reasoning for lifting the ban on hydraulic fracturing to recover gas and oil from shale, which has an estimated commercial value in the UK of £1500 billion. We demonstrated that hydraulic fractures will not be tall enough to cause contamination of water supplies where there is a sufficient vertical separation (> 600 m) between the shale reservoir and the drinking water aquifer. Durham research has also provided critical data needed by national environment agencies setting regulations, oil and gas companies seeking permission from regulators to drill wells and for local communities that are objecting to hydraulic fracturing.
Impacts: I) Operational decision making during the 2010 Eyjafjallajökull eruption, including that of the UK Civil Aviation Authority to relax airspace restrictions over Europe. II) Strategic planning for future volcanic hazards, including the 2012 classification by the UK National Risk Register of Civil Emergencies of Icelandic volcanic eruptions as a `highest priority risk'.
Significance and reach: The relaxation of airspace restrictions over Europe affected up to ten million travellers and mitigated on-going airline industry costs of up to £130 million per day.
Underpinned by: Research into the size, frequency and dynamics of Icelandic volcanic eruptions, undertaken at the University of Edinburgh (2006 — January 2013).
Cranfield's work on ethylene supplemented storage is now exploited in the supply chains to major supermarkets in the UK, including Waitrose and Tesco, reducing waste and avoiding volatility in supply for fresh food products such as onions and potatoes. By prolonging storage life by up to six weeks it is also having a positive impact on the UK's self-sufficiency in these products, displacing imports from overseas.
Complementary work has also led to commercial ethylene scrubbing technologies for packaging, which typically save around 50% of in-store waste and add two days to the product life for a range of fruit and vegetables. Such packing is now in use in most mainstream UK supermarkets, and in the USA where it has created a new export market for the manufacturer.
Cardiff University's research in acoustic emission monitoring and refined data analysis has been applied to large, complex structures and has subsequently transformed the inspection processes of concrete and steel bridges. This has been commercialised by Mistras Group Ltd. to provide a safer, more reliable and progressive means of bridge monitoring, enabling the company to acquire a global reputation and increase its turnover to £7.5M per year — £5M relating to Cardiff research. Cardiff's innovations have had major international impacts (in UK, Europe, India and USA) through:
Innovative geochemical research led by Selby at Durham has permitted savings of up to $70M in global mineral and petroleum exploration programmes (e.g., Andes of S. America; West of Shetlands oilfields). Selby's research has developed a unique geochemical toolbox using rhenium, osmium, platinum and palladium that constrain more accurate geological models leading to better reserve predictions. The toolbox provides previously unavailable geological time constraints and source identification of resources (e.g., copper, gold, crude oil) that gives mineral and/or petroleum companies an enhanced economic advantage by improving reserve estimates and/or reducing exploration budgets and/or minimising the environmental impacts of exploration.
