The
UK’s first research programme to investigate the impacts of ocean
acidification has been launched involving 101 scientists from 21 of
the UK’s top scientific institutions. The UK Ocean Acidification
Research Programme consists of several projects working together to
investigate different aspects of this global issue.
The world’s seas are absorbing high levels of carbon dioxide
(CO2) mainly produced by human activities, such as
fossil fuel burning. The absorbed CO2 fundamentally
changes the chemistry of oceans which results in a rise in ocean
acidity. Since the start of the Industrial Revolution ocean acidity
has risen by about 30%. Ocean acidification is estimated to be
currently occurring at a rate faster than has been experienced
during the last 20 million years. If CO2 emissions
continue to rise and the acidity of the World’s oceans and seas
continues to increase at this rate this could have serious
consequences for important cycles that drive the climate as well as
marine life (e.g. corals, shellfish, algae and the plankton that
form the base of the food chain) within this century. Such impacts
could reach far beyond the marine environment, to that of climate,
food provision and human health and well-being.
Richard Benyon, Parliamentary Under-Secretary for Natural
Environment and Fisheries, said:
“The effects of climate change on land have been well documented
yet we are only just beginning to explore the damage that rising
CO2 levels could have on our marine ecosystems.”
“The UK is the world leader in marine science and it is projects
such as this that will help us understand the effects of ocean
acidification on the world’s seas and oceans. This research
programme is vital to help us meet the challenges ocean
acidification presents.”
The need for more knowledge about ocean acidification and how it
will impact upon the oceans environmentally, socially and
economically is recognised as a key issue, and the six new projects
have been designed to answer some of the most pressing questions.
They are funded by the Natural Environment Research Council (NERC),
the Department for Environment, Food and Rural Affairs (Defra) and
the Department of Energy and Climate Change (DECC) under the
auspices of the Living with Environmental Change partnership.
Six research projects have now been funded, each delivering a
key part of the £12 million UK Ocean Acidification Research
Programme, designed to answer the following questions:
- How much variability is there in oceanic
CO2 uptake and what are the trends for the future? Led
by Professor Andrew Watson, University of East
Anglia.
- What are the impacts of ocean
acidification on key benthic (seabed) ecosystems, communities,
habitats, species and their life cycles? Led by Dr Stephen
Widdicombe, Plymouth Marine Laboratory
- How will ocean acidification affect the
biology of surface ocean communities and biogeochemistry, and how
that might feedback to climate? Led by Dr Toby Tyrrell,
National Oceanography Centre
- What are the potential impacts of ocean
acidification on the ocean and how it might amplify rising
CO2 and climate change? Led by Dr Andy Ridgwell,
University of Bristol
- How will ocean acidification impact
ecosystems and chemical cycling in UK and Arctic regional seas? Led
by Dr Jerry Blackford, Plymouth Marine
Laboratory
- What were the effects of rapid ocean
acidification events in the Earth’s past? Led by Professor
Paul Pearson, Cardiff University
These projects are supported by a national analytical facility
led by Professor Eric Achterberg, National Oceanography Centre.
Plymouth Marine Laboratory (PML), uniquely, is leading two of
the programme’s six projects as well as contributing to two others,
a testament to the world class research carried out at PML, and its
reputation in the field of ocean acidification studies.
Dr Steve Widdicombe, a Head of Science at PML, is running a team
looking at how ocean acidification and global warming will impact
upon seabed living organisms and, in turn, how that might affect
the way ocean food chains function, and ultimately dictate how we
use ocean resources in a sustainable way. One of the questions Dr
Widdicombe hopes to answer is whether these plants and animals can
adapt to the changes taking place in valuable coastal habitats.
The second group will be working on developing computer models,
led by Jerry Blackford, built from the best available knowledge and
observations (including UK Met Office future climate scenarios), to
understand the magnitude and timescale of any changes through ocean
acidification and its better known twin phenomenon of climate
change. The project focuses on two regions: the shelf seas of the
UK and Europe, which are a very important provider of resources,
and Arctic regional seas, which will be the first to show
affects.
In addition to the research projects, PML has also been
co-ordinating how the knowledge gained from across the UK Ocean
Acidification Research Programme will be made available to
stakeholders, policy makers, other international research
programmes, and the public.
NERC Chief Executive, Professor Alan Thorpe, said: “Ocean
acidification is an important scientific priority in NERC’s
Strategy as well as in the recently published UK Marine Science
Strategy. I am very pleased that we have been able to address this
critical science and policy issue with Defra and DECC, as part of
the Living with Environmental Change programme. This initiative,
one of the first to be funded by any nation, ensures that the UK
will remain at the forefront of ocean acidification research.”
Professor Robert Watson, Defra’s Chief Science Adviser,
commented: "Ocean acidification may be a relatively recently
identified phenomenon but its potential impact is likely to have
wide ramifications through the ocean. We need to understand how
much of a problem it might be, how quickly we will start to feel
its effects and how we might mitigate any impacts. The UK has been
at the forefront of ocean acidification research and this Programme
will ensure the excellent work continues. By following a
multi-disciplinary approach, looking at a range of aspects of ocean
acidification, we can bring together scientists across disciplines
in order to gain as complete a picture of how the ocean will react
to increasing acidity and how its diverse life forms will cope or
adapt in the future."
