Summary of the impact

The Plymouth University marine carbon team was the first to investigate ecological consequences of ocean acidification, and carbon capture and storage leakage. The findings have impacted on US legislation and are key to the UK ocean acidification research programme. The research is highlighted in the European Science Foundations' Science Policy Briefing on Impacts of Ocean Acidification (2009), the United Nations' Emerging Issues Bulletin on `Environmental consequence of ocean acidification: a threat to food security' (2010), the US `National Strategy to Meet the Challenges of a Changing Ocean' (2010) and the Intergovernmental Panel on Climate Change `Ocean Acidification Report' (2011).

Underpinning research

This case study highlights the impact of a body of research into marine carbon undertaken at Plymouth University by Hall-Spencer (Royal Society University Research Fellow 2002-2008, Professor of Marine Biology Plymouth University) and Spicer (Professor of Marine Zoology 2005-2013 Plymouth University). This research is vital to inform society of the consequences of unprecedented changes to the ecology and chemistry of our coasts. Without this information, policy makers are unable to assess the true costs and dangers of continued carbon dioxide emissions. The first indication that exposure to CO2-rich water could result in biological effects that were not straight-forward to interpret came from a NERC-funded studentship (2006, Spicer as principal supervisor). This found that ocean acidification increased, not decreased, calcification in fish - but that there were trade-offs as we also found evidence of muscle wastage Our team built the first aquaria used to study biological effects of CO2, based on designs Spicer had been using to investigate oxygen and carbon dioxide effects on marine life since 1987. We have used these world-class facilities to show how carbon dioxide affects marine organisms, data that are used to predict future impacts on ecosystems in the UK and worldwide. The award of a major NERC consortium grant has allowed us to investigate the long-term effects of ocean acidification on a range of marine life and to study the evolutionary responses of marine animals to ocean acidification and temperature.

To augment this laboratory work Hall-Spencer spearheaded the use of natural analogues for predicting future effects of ocean acidification on society and to inform policy on Carbon Capture and Storage. He assembled a team of researchers; Dr Rodolfo-Metalpa is his Plymouth University PDRA, Ms Rowley and Ransome were both Plymouth University students who with Dr Martin from CNRS France carried out the fieldwork. Dr Fine from Bar-Ilan University Israel provided expertise on corals, Dr Turner from UEA provided expertise on trace gases, Dr Tedesco from University of Naples provided expertise on volcanology and Dr Buia from Stazione zoological Naples provided seagrass expertise. By studying marine organisms along natural gradients of CO2, he was able to show the ecosystem-level effects of long-term exposure. This resulted in a land-mark publication in Nature (Hall-Spencer et al. 2008), which has set the standard for working with natural analogues, generating considerable public and scientific interest (223 ISI citations). Our natural analogue approach is being adopted worldwide with our team now involved with similar studies in the Pacific (US, Canada, Mexico, Australia, Papua New Guinea) and around Europe (Azores, Greece, Italy). The biological responses observed along CO2 gradients have been used to predict how coasts will change over the coming decades and are being used to inform policy decisions. Our peer-reviewed published studies show the effects of increasing carbon dioxide levels on marine bacteria, algae, plankton, sponges, corals, worms, crustaceans, molluscs, bryozoans and echinoderms as well as fish and the fishing industry. The CO2 gradients around volcanic vents have also been used as an opportunity to train a new generation of professionals from a multitude of different countries and to highlight the importance of reducing carbon dioxide emissions, exploring carbon capture options and increasing protection for coastal habitats (e.g., http://medsea-project.eu/training/co2-vents-training-activity/).

Details of the impact

The main impacts of our research are on marine policy, regulation and guidelines designed to bring environmental improvements and through informing governments and industry on carbon capture and storage leaks as well as threats of ocean acidification to food security.

The research has had international impact. As a result of research into ocean acidification and carbon capture, Hall-Spencer has contributed to the drafting of the science basis of the next round of policy documents for the Intergovernmental Panel on Climate Change (Evidence 1). Through EU FP7 programmes (EPOCA, KnowSeas, MedSeA) he has provided presentations and draft policy documents to staff responsible for informing governing bodies on ocean acidification at the United Nations Environment Programme, EC DG Research and Innovation, the European Science Foundation and the International Union for the Conservation of Nature. As highlighted by the Senior Advisor of the International Union for Conservation of Nature "The influence of the research carried out by the marine carbon group at Plymouth University has ensured that ocean acidification, and the potential of carbon sequestration leaks to cause harm to the marine environment, are now being considered in depth alongside potential solutions to the problem such as improved marine conservation and the role of seagrasses as a Blue Carbon resource."

The research has been used as evidence in drawing up the US FORAM Act in 2008, has been incorporated into the US school curriculum, and has had impact on knowledge and behaviours of practitioners/policy makers having been incorporated into national and international strategies (e.g. National Research Council of the National Academies 2010). As stated by the United States Department of Commerce "The influence of the research carried out by the Marine Carbon Research Group at Plymouth University is international. In the USA there was explicit reference to the Plymouth University ocean acidification work in the U.S. Senate when hearing evidence for the federal Acidification Research and Monitoring Act"

The research on natural analogs for CO2 exposure is being used as evidence for the need to boost `Blue Carbon' IUCN initiatives and the shift from fossil fuels to renewable sources of energy (see Evidence 2-3).

The research contributed substantially to the UK setting up a £12 million Ocean Acidification research Programme (2010-2014). The team a) assist the UK government (via DEFRA and DECC) in their delivery of statutory obligations under national legislative drivers (e.g. UK Biodiversity Action Plan, UK Marine and Coastal Access Bill), provide information to aid the assessment process for the UK Regional Seas via the UKMMAS Charting Progress III (in 2015) and the OSPAR Assessment Framework and support the design and implementation of measures needed to achieve Good Environmental Status in UK Regional Seas; (b) assist overseas governments with similar environmental protection remits; (c) allow government-backed international initiatives such as EPOCA, BIOACID, MedSeA, Mares & UKOOA to contextualise the work they are doing separately on Ocean Acidification (see Evidence 4). As stated by the Knowledge Exchange Coordinator of the UK Ocean Acidification Research programme "The team's work has made a major contribution to a number of key national and international research initiatives to inform policy makers of the future impact of OA on marine ecosystems and society".

More widely the research has had impacts on public discourse and raised societal interest in the effects of ocean acidification. Work by the marine carbon research group has been covered extensively by newspapers and on TV, the National Geographic Magazine, and in several science documentaries that have been shown globally (see Evidence 4). Thus the marine carbon research has intrinsic interest, but is also designed to predict the effects of ocean acidification and marine carbon capture and storage driven by legislative and regulatory considerations.
