Underwater lands that were submerged following the last Ice Age could yield vital clues about our current approach to climate change. Global experts in archaeology, climate change, history and oceanography are discussing how we can unlock these secrets at a prestigious Royal Society meeting on 15 May 2017.
Among the speakers will be Dr Eugene Ch’ng, an expert in modelling and visualization of large ancient terrestrial and marine landscapes from the University of Nottingham Ningbo China. Dr Ch’ng heads the NVIDIA Joint-Lab on Mixed Reality and is project lead for complex systems modelling and simulation of the European Research Coucil’s (ERC) ‘Lost Frontiers’ research project.
Dr Ch’ng said: “The modelling, mapping and analysis of massive ancient terrestrial and marine landscape ecology, environmental change, population movement spanning hundreds of thousands of square kilometres and hundreds of millions of agents – such as the flora, fauna, people and environmental factors - have implications for real-world discovery and applications. However, the greatest barrier to realising massive agent-based modelling is the computational resources required to store and simulate these detailed interactions within 3D terrains. We need to develop strategies for scalable agent-based modelling, simulation and visualisation in time and space of large ancient landscapes.”
After the last Ice Age, which ended around 20,000 years ago, global warming caused many populated landscapes to sink beneath the sea. Vast areas of land were lost around the world as ice caps melted and sea levels rose. These included the stretch of land between Britain and mainland Europe, known as Doggerland, but also even larger areas in South East Asia and the lands around and between modern Siberia and Alaska - areas known respectively as Sundaland and Beringia.
Although we know that climate change occurs periodically throughout history, we know relatively little about how our ancestors coped with such changes, and what effects a warming climate might have had on colonisation and migration. Research in these areas could help inform climate change debates in our current geological age – the Anthropocene – which is defined by the permanent and overwhelming impact of humans on the environment.
In his talk Dr Ch’ng will propose and discuss high performance computing techniques that can potentially simulate hypothetical models of massive ecological scenarios spanning landscapes up to 100,000 square kilometres and going back as far as 20,000 years.
The Royal Society’s 2017 Theo Murphy International Scientific Meeting, is organised by archaeologists at the Universities of Bradford, York, St Andrews and Warwick, and the University of Nottingham Ningbo China. It will bring together world class scientists in this trans-disciplinary project to explore how the latest technologies can be used to model and analyse underwater landscapes, many of which have, until recently, been inaccessible to researchers.
Samples taken from marine sediment cores are now yielding detailed data about the flora and fauna within these areas, but a more co-ordinated approach is needed to draw together this new wealth of information. The Theo Murphy Meeting will enable experts to start to develop large-scale projects and ways of studying these lost lands and understand their contemporary relevance.
Vince Gaffney, Professor of Archaeology at the University of Bradford, who is co-ordinating the meeting said: “These submerged landscapes have so far been inaccessible to archaeologists. The data that has been gathered has often been fragmentary, and many areas of interest are sealed beneath marine sediments. But modern technologies are now enabling archaeologists to mine these sites and extract new information about how these landscapes responded to huge environmental, cultural and technological changes. The opportunity to bring together specialists working on these landscapes will yield new insights and approaches to current climate change debates.”
The Royal Society’s 2017 Theo Murphy International Scientific Meeting, ‘Lost and future worlds: marine palaeolandscapes and the historic impact of long-term climate change’ takes place at the Kavli Royal Society Centre, Chicheley Hall, Newport Pagnell, Buckinghamshire, MK16 9JJ on Monday 15 May to Tuesday 16 May 2017.
A programme for the Theo Murphy Meeting is available to download. The meeting is organised by Professor Vincent Gaffney and Dr Philip Murgatroyd, University of Bradford, Professor Geoff Bailey, University of York, Dr Eugene Ch’ng, University of Nottingham Ningbo China, Dr Richard Bates, University of St Andrews, and Professor Robin G. Allaby, University of Warwick.
The NVIDIA Joint-Lab on Mixed Reality, NVIDIA Technology Centre in our China Campus exists as a hub for interdisciplinary research. The lab aims to advance our understanding of the co-existence of the physical and the virtual, and of man and machine. The research is data-driven, with data-mining, machine learning and interactive visualisation as core activities – making data meaningful by bridging the incomprehensibility of raw data with the rationality of our human senses.

Notes to editors: The University of Nottingham has 43,000 students and is ‘the nearest Britain has to a truly global university, with a “distinct” approach to internationalisation, which rests on those full-scale campuses in China and Malaysia, as well as a large presence in its home city.’ (Times Good University Guide 2016). It is also one of the most popular universities in the UK among graduate employers and was named University of the Year for Graduate Employment in the 2017 The Times and The Sunday Times Good University Guide. It is ranked in the world’s top 75 by the QS World University Rankings 2015/16, and 8th in the UK for research power according to the Research Excellence Framework 2014. It has been voted the world’s greenest campus for four years running, according to Greenmetrics Ranking of World Universities.
Impact: The Nottingham Campaign, its biggest-ever fundraising campaign, is delivering the University’s vision to change lives, tackle global issues and shape the future. More news…
