The Bristol Volcanology Group: Managing Britain’s volcanic crises

When Professor Steve Sparks moved to Bristol from Cambridge in 1989 to take up the Chair of Geology in the School of Earth Sciences little did he know what was in store for him. His time at Bristol would see him advise the government and become one of the most cited scientists of all time.

Sparks’s extraordinary journey as head of the volcanology group has lead it to study volcanism on every continent and has allowed it to grow from one man to a thriving collective of staff, researchers and students. The world-class science produced by the group has resulted in it receiving the Queen’s Anniversary Prize; the highest accolade in higher education.

Naturally, this evolution has been heavily influenced by volcanoes.  Unlike many sciences, the progress of volcanology can be episodic- driven by key eruptions and crises. For the Bristol group, two events have defined their work which has, in turn, altered the course of the science:

The eruption on the Island of Montserrat lasted from 1995 to 1997, killed 23 people and displaced several thousand.  As Montserrat is a British dependant territory, the British government was closely engaged in managing the crisis and wasted little time roping in Bristol’s volcanic expertise as Sparks explains: “Bristol was a key partner in establishing the Volcano Observatory on the island and several Bristol staff and PhD students were involved in the monitoring effort in the first few years.” This partnership has continued for the past two decades with Professors Sparks and Aspinall acting as directors of the observatory and heading up the advisory committee ever since. In addition, the research resulting from the eruption has contributed invaluable information to the science of volcanology including causes of volcanic cyclicity and eruptions.

More recently in 2010, the Eyjafjallajokull ash crisis cost the European economy $5 billion through the closure of airspace. In the midst of the decision-making surrounding this closure was a SAGE (Scientific Advisory Group for Emergencies) meeting attended by six volcanologists, of which three were from Bristol. Bristol’s Professor Willy Aspinall, was one of the three called to advise, alongside Dr Matt Watson and Professor Sparks. He described the meeting as a ‘spectrum of people working in many areas from civil aviation to defence’.

The role Bristol played was pivotal in the national response and was a turning point for the group as a whole as Watson explains ‘Eyja changed how we operated. Volcanology had previously comprised mostly of research produced for other researchers, but this was the first time we could use it practically in a crisis’.

Indeed, not only did it highlight the need for more applied approach to volcanology, it also prompted whole new field of research on volcanic ash involving analysis of ash deposits and advances in remote sensing techniques.  Such challenges were met head on by the group that has a huge breadth of research capabilities, from geophysics to geochemistry to petrology. 

Looking to the future, the group’s challenge is to be prepared for new eruptions, wherever they may be.  The researchers are working in regions all over the world including countries such as Guatemala and Ethiopia. Bristol volcanologists hope to expand this aspect of their research through opportunities such as the Global Challenges Research Fund which will draw together expertise from all corners of the group to address volcanic challenges in less developed nations.

In recent years, Sparks has stepped down as the head of the group allowing for the appointment of Professor Kathy Cashman as AXA professor of volcanology and the group’s new lead.  Now, 27 years after it began, the group is not showing any signs of slowing down. The question is, when will next episode in the group’s history erupt?

The Diamond Battery – your ideas for future energy generation

On Friday 25th November, at the Cabot Institute Annual Lecture, a new energy technology was unveiled that uses diamonds to generate electricity from nuclear waste. Researchers at the University of Bristol, led by Prof. Tom Scott, have created a prototype battery that incorporates radioactive Nickel-63 into a diamond, which is then able to generate a small electrical current.
Details of this technology can be found in our official press release here: http://www.bristol.ac.uk/news/2016/november/diamond-power.html.
Despite the low power of the batteries (relative to current technologies), they could have an exceptionally long lifespan, taking 5730 years to reach 50% battery power. Because of this, Professor Tom Scott explains:
“We envision these batteries to be used in situations where it is not feasible to charge or replace conventional batteries. Obvious applications would be in low-power electrical devices where long life of the energy source is needed, such as pacemakers, satellite…

A response to Trump's withdrawal from the Paris Agreement

The decision by President Trump to withdraw from the Paris Agreement on Climate Change puts the United States at odds with both science and global geopolitical norms.  The fundamentals of climate change remain unambiguous: greenhouse gas concentrations are increasing, they are increasing because of human action, the increase will cause warming, and that warming creates risks of extreme weather, food crises and sea level rise. That does not mean that scientists can predict all of the consequences of global warming, much work needs to be done, but the risks are both profound and clear. Nor do we know what the best solutions will be - there is need for a robust debate about the nature, fairness and efficacy of different decarbonisation policies and technologies as well as the balance of responsibility; the Paris Agreement, despite its faults with respect to obligation and enforcement, allowed great flexibility in that regard, which is why nearly every nation on Earth is a signatory.

What happens when you let PhD students and post-docs organise a meeting?

As plant science PhD students, we feel it is vital to share our research with other scientists to generate new ideas for collaborative projects. For this reason we decided to organise the ‘Innovations in Plant Science to Feed a Changing World’ workshop, which was held in the University of Bristol Biological Sciences department in February 2017. The delegates included early-career scientists from Kyoto University, Heidelberg University and of course the University of Bristol.

The University of Bristol has a long-standing partnership with Kyoto University and more recently, Heidelberg University, as our plant science groups share overlapping research areas. The main aim of the workshop was to encourage novel collaboration opportunities between the plant science groups, which would give rise to future projects, publications and ultimately funding.

Last year, Kyoto University hosted a highly engaging and productive workshop (see Sarah Jose’s blog post last year) for early-career scientist…
