UKOA is a five-year, £12 million research programme that began in 2010. It involves 27 research institutes in the UK, has close links with other ocean acidification programmes around the world and is co-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).
Ocean acidification occurs as carbon dioxide (CO2) dissolves in seawater and forms carbonic acid. The oceans absorb roughly half of human CO2 emissions and, if we continue emitting CO2 at the same rate, the acidity (hydrogen ion concentration) of the upper ocean is predicted to increase by about 150% by 2100. This pH change has other important implications for ocean chemistry – and marine life.
UKOA aims to better predict the chemical changes involved and their knock-on effects for organisms and ecosystems and thereby help provide effective policy advice on the potential size and timescale of risks.
BODC's role involves the quality control, dissemination and stewardship of UKOA data, as well as facilitating data exchange within the UKOA community and providing advice on data management best practice. Our data management web pages provide background information about the UKOA programme, as well as inventories of research cruises and associated datasets.
The pages are designed to promote data sharing and collaboration between programme participants and the wider scientific community.
